I'm going to need to watch this video like 10 times to get this.
Haha you made me laugh, thanks for your feedback. I take it that the information is useful then. It always remains a challenge to find the right pace in these videos. Could you tell me which topics went too fast and/or would require more explanation? I will adjust the content accordingly. Looking forward for your reply, Jesse.
😂 me too!
Nice and straightforward content, easy explained👍🏻.
Asklve solar maybe meant that there's a lot if useful infos. so you need to watch it again and again to grab it all, that's what I've personally experienced already.
Excellent info, logically presented, great, clear audio. Thanks!
Thank you for your message Spok, that is great feedback to receive. Live long and prosper! Jesse
Fantastic video. I'm just dipping my toes into the subject and this has been very clear and informative. Thank you.
Glad it was helpful!
This was SO CLEAR and helpful. Thank you 🙏

what about FLYPOWER 12v 100Ah LifePo4 Battery
We are connected to the grid and have enough solar panels that we are accumulating credit on our account. I would like to install a battery/ batteries as a way to use less electricity at night and also as backup in times of blackouts. What would you suggest.
Hello I'm from the UK and I'm very new to understanding these systems. I liked your explanation but I was still confused I'm willing to learn as much as I can. I live with my family in a flat on the top floor and I have long balcony. Fortunately for me I am facing the sunrise directly. I wanted to install solar panels in front of my balcony and because of the length I believe I can easily setup upto six decent sized panels. I would have to make some kind of housing or secure contraption to hold the panels in the desired angle, this is something I can do.
Is it possible to use car batteries in line with a inverter and how can I determine which is the best option. I'm open to all ideas and obviously I wish to gain the best working solution, can you please help me? Many thanks 👍
That sounds like an exciting project! Thanks for sharing. While this video has a focus on batter characteristics and selection approaches, based on your question I believe you might also benefit from the content shared through the following videos:

I am using 24v settings can you tell me what to set my controller on for hi voltage and low voltage and float voltage for lithium batterys
I just put a 15 KW system on my house and Iam total electric and the Battle Born batteries seam to me the best battery out there now. I have 2 100 amp batteries in my truck camper and have no room on my roof for solar panels. But I could have a stainless steel rack on top of all the stuff on my roof. But for now I have a Renorgy DC to DC 50 amp charger when driving and I do have a built in 2500 watt generator and I’ve changed out my converter that came with camper so I changed it out for a lithium one that works fine. I had to stay with the wireing 45 amps so that’s what my converter has wire size I had to go with. Sorry got off track here but how many 100 amp hour batteries would I need to power my house if power would goes out. So normally my power goes out for about 5 hours so I figured I would double that to 10 hours. The salesman said I would be money ahead to get a whole house propane generator and could use propane for a heat source so I got a 30000 btu blue flame ventless heater and I have set up the heater for some test and it does heat the first floor of my house no problem at all it has s pilot light and a thermostat so it kicks on and off as needed and it just sips fuel and I got a 15000 watt generator electric start and it runs on gas or propane so Iam going to put a 250 gallon tank and propane doesn’t degrade like gas or diesel propane last for ever so that’s the perfect fuel for long turn storage and I have a rental house next door so Iam going to pull the propane tank out and poor a concrete pad for both tanks to set on and have to figure a way to get propane to the rental out of my tank if she runs out but need some way to meter it so she can pay for propane she used. So I will run a line to my house for back up heat and to feed my generator and I would be good to go. So would you say that would be as good or better than a back up battery bank as back up ?
Hi Jesse, How to calculate the cycles of the battery if it is charged and discharged several times per day but not discharged till DoD?
So it is better to DOD at 100% or rated discharge before charging , to prolong lifespan , is this correct ?
Thanks for the info maybe one day you could explain where the price difference comes from .400U$ vs 1500U$ with apparently the same power
Is there a difference Lithium polymer ( li-po) ..and other gel batteries..
Hi... I love watching your videos. I have a very odd question. I am living in Italy and the cost per KWH are getting out of hand.
I was thinking of getting a solar system..... ok till now nothing special as of a question.
My father lives next door in an attached home and was thinking of sharing my solar system with my dads house with an ats switch without having 2 set ups.
Is this even possible or am I better off with 2 solar systems?
If I have opt for 2 systems is there some way we can share a huge battey instead of having 2 separate ones?
Respect do your efforts very informative, and I definitely will be on the side of the gas power station it’s more convenient until we see a big shift in the energy industry

Do a video of your recommendation for the ideal solar panel battery power setup for an off grid 3000 sqft house to power two refrigerators, computer, tv, dryer, 3 fans, for 4 hrs a day.
Hello Sean, thanks for your feedback and video topic suggestion. I think it is a great idea to share design recommendations for different systems, I will include your system configuration as one of the setups. I will share it with you when it is ready.
Thanks for the suggestion, Jesse.
Yes,this is the area where I am having a problem understanding the right battery that will work in my micro climate and also has the other traits I need. For there years I did want to go solar and I did buy my first deep cell battery as a learning project. But I did not check and find out if it would deal with the temperature range in the micro climate I want to use it in. It was my big mistake.
Last Friday I was told about Fullriver battery’s and they can deal with temperatures as low as -40 below O.
The first deep cell battery I did buy can not deal with cold temperatures.
I as a newbie I have to have a better understanding and full understanding on Deep cell battery selection and and the micro climate there going to be used in.
I need batteries that can deal with bad winter weather.
Regards
Hope
Hello Hope, thank you for your excellent question. You what, I think I will make a separate video on how to deal with cold weather conditions and how to select the right battery for it. Stay tuned! Jesse.
Hey great video! I have a question. Towards the end you mentioned DOD and completing cycles etc.. With your 1000 cycle example, what if I’m not completing the cycle at all. What if I discharge to 75% instead of 50%, then recharge. Would I maintain that 1000 cycle lifespan indefinitely ?
Hello Thomas, thank you for your [excellent!] question. If only it were true that with a 75% DOD you would get indefinite lifespan, that would change the energy market substantially. Your question makes a lot of sense: In general if you 'use less' of the battery's capacity, you will get substantially more lifetime [=cycles] out of the battery. This in fact is part of the reason why it is recommended not to go beyond the typical 50% DOD point.
If this interests you, you might enjoy downloading a specification sheet of a random battery [Trojan & Rolls have easy websites] look up the DOD vs Cycle graph. Good luck and enjoy! All the best, Jesse
At 50% DoD my Gel batteries would give me 180ah on my 24v system. So why would installers recommend me getting a 100ah Lithium battery, which at maximum 80% DoD would be 80ah? Yes I do get the issue of C-rating but my overall capacity is way lower on Lithium which isn’t sensible. Maybe I’m missing something, please help.
Hi Jesse,
Very good information. Thanks. May i know whether i can parallel two different types of batteries such as 150 ah of C10 and 200 ah of C 20. What will be its efficiency? Will they perform to optimum? Awaiting your valuable reply/ suggestions.
Saji John.
Hi Sajy, thanks for your message. Connecting batteries with different capacities is in general not advisable. One of the important goals in conventional battery bank configuration [without dedicated per-battery BMS systems] is to make all batteries work together as a team, so they will all contribute/work just as hard as the other ones. I hope this helps, it sounds you are on your way of figuring things out!
Good luck with your project, I am sure you are having fun. Jesse.
On a gel battery I have a reading of 13.14 after the battery has not been in use for 4 weeks yet it does not last a full cycle and is 5 years old
Thankyou Jesse, is it a complicated method to choose the best battery to start up a microgrid?, Lets say that someone with money ended up by the coast of Tanzania Africa, and decides to set up their own microgrid station eventually developing it into an self sufficient and self efficient island. Which type of battery would be best for that microgrid station to have? Thank you in advance.

Could you do a video on the eg4 chargeverter please?
That is an excellent suggestion Shaun, thank you and yes I will!
Great video Jesse. I want to move to Cameroon, Africa and initiate a Solar energy Company. In addition to course you provide which other courses would you recommend I take to fully prepare myself for this endeavour. Thanks.
Hello Eugene, it is good to hear from you. What an exciting idea! I do not know what your professional background is, though a basic understanding of electrical engineering might be useful as well. I am sure there are several courses on this topic available as well. Keep me posted about this endeavor! Good luck and all the best. Jesse
Dear Jessie I am looking for a back up solar power battery system for my apartment. That mean I like to keep the batteries charged from the grid until the power is gone. What would be the best type of batteries to use and what kind of charging controller is the right one to also use solar for recharging in case of emergency. Thanks and BR from Hong Kong
Hello Dirk, thank you for your message. Please contact me through the main website:

Jesse.
One of the things I'm trying to figure out and a question I have is if the solar charge controllers really will shut off when the voltage and battery banks have too much power in them? I'm hoping someone might have information on this? They SAY they will. But I've noticed a lot of charge controllers don't work the way they say they should. And I'm worried about this because of fire risk. The cheap little 20 dollar blue one specifically that a lot of people use I found out was garbage. And that one doesn't shut off the way it should, and it wasn't actually pushing power the right way it should into the battery bank when things were clear and energy was going through solar panels also.
This is part of why I ask. I've since gone to a better quality charge controller... but it leaves you with the question, if the higher cost ones will safely shut off at max voltage also still if others are defective?
Thanks.
Hi Jesse, I understand your video, however I have a swimming pool that has a 9kw heater that runs for 7 hours a night, how big would the battery have to be to be able to run this heater ? And how many solar panels would I need to keep the battery charged ? Many thanks Paul Hayter
Go for the max number
I have a small 100watt solar panel kit with a 20amp charger and a 75-1500watt inverter. I just want to run a 700watt coffee maker for 10 minutes once a day. What type or size of battery do I need?

Hi sir really wanna know the best battery appellation right now and that of the company. Not forgetting the cose
Hello Nsah, thank you for your message and question. Can you please further clarify what it is that you would like to learn. And out of curiosity: Where does your family name come from? Zambia or Malawi perhaps? It sounds great. All the best, Jesse.
Thanks for the video Jesse! Maybe a dumb question, but what happens if I discharge my battery 100% each time. I'll still have the 1000 cycles right? In this case with the double of power generated?
Hi Joao, thanks for you message. The only dumb question is the one which is not asked :). Generally speaking, 100% discharge of Lead-Acid based battery is not recommended, since it will severely impact the lifetime of you battery. For the specific lifetime-discharge relationship of your battery, please check you specification sheet. It is often on the second or third page. Good luck! Jesse
@@SolarSolution never discharged a lead-acid battery more than 50%.
Very nice video, but I want to know if the weather can influence on lifetime of the battery, and if yes, how does it work?
Hello Filipe, thank you for your [excellent!] question. The environmental conditions can definitely have an influence on the operation and lifetime expectancy of your battery.

Yes it’s possible to use a car battery, but a car battery really is best suited for quick-fire start up rather than for a lengthy discharge or draw from it. If Lithium isn’t an option, I would advise Gel deep cycle battery(ies) and make sure you place them in a place/location that would not seriously affected by cold or hot weather. Optimally 25°Celcius or as close to that is advisable. Also look to getting an MPPT charge controller rather than a PWM Charge controller, you can research on the reasons and make sure your system has protection for lightning both on the AC & DC side, and run a grounding cable for your panels. Best of luck!
Can i do AHP MACD for the selection of battery(for solar purpose). what are the parameters if so...
Price; technical criteria(cycle life,size and weight,efficiency, DOD; environmental impact...are sufficient ?🤔
My alternatives are flooded lead acid , AGM, gel and lithium ion(LiFePO4) as some vendor are interested on it and setup accordingly..thanks
Hello Bishnu, thank you for your questions. You are welcome to book a consultation through the main website.
Are there any problems using normal lead acid batteries in a boat? The battery acid will certainly leave the lead plates dry again and again in strong waves ... but it is the best price-performance ratio.
Hi Lars, thanks for your message and your question. I would like to draw your attention to the pinned comment at the top. All the best, Jesse.
Dear Jesse
i'am opening solar street light business in my country. As the delivery time is very long (2 months), what do you recommend to help keeping the batteries in good working condition when i receive the good. Also, sometime after the 2 months delivery time, i have to store them before selling them. On some good, the light become poor because of the batteries. Is ther any frequency i have to put them in sun to keep them awake etc...

So I got a little 1k watt inverter, and have an extra car battery right, so if I buy a little solar panel, could I hook up the battery and the inverter and have a self charging never dying inverter?
Hello Adam, thank you for your message and question. The parts you mentioned are indeed some of the core elements of battery-based solar energy systems. You might also want to research topics such as fuses, breakers, wiring, solar charge controllers, and the difference between deep cycle and starter batteries. Enjoy the learning process!
All the best,
Jesse
@@SolarSolution Adam, I had a 50 watt solar panel, 10amp controller and 400 watt inverter. It ran my lights in my shed. My shed had 2 4 door led shop lights. I would just flip the inverter on and the lights would come on. I did not use the lights all night it was only for 15-30 minutes whenever I needed something out of the shed at night. It worked very well.
which one is best, lead acid battery, Li-Ion battery, Redox-Flow battery, Deep cycle battery and shallow cycle battery?
Hi Stephen, thank you for you question. The type of battery which will be the best choice for your setup, is a result of the defined system performance requirements. In other words: What you want to get out of your system, defines which kind of battery is a best-fit for your particular situation. Good luck! Jesse
having 2 batteries of 12volt each 200amp.
which option will give more backup time.
options : connecting both in parallel to get 12v 400 amp.
Option-2 : connecting both in series to get 24volt and 200 amp..
Parallel will give you more backup time, but less power go run bigger appliance, series connection is the opposite!
Yes i think the lithium way is the feature👍
Hi Dana! Lithiums are great, I agree. All the best, Jesse.
Hey Jessie, great videos, if i take your udemy course will it teach me what i need to know to set up the system myself and save on instillation costs?
Hello WhoDaBoss, thanks for your message: I have something better for you then my [possibly biased] answer, if you follow the link in the description, you will be able to preview several lectures for free. I am sure this will answer your question, if not let me know! Enjoy, Jesse.
@@SolarSolution thank you!!!
@@SolarSolution so i watched all the free videos, i did not see anything on self instillation, im guessing it is not covered but what are your thoughts on self instillation in general?
@@SolarSolution (i am still interested in buying the course as this is really interesting and will be really helpful i think)
You are correct, step-by-step self installation is not covered
How many panels do I need and which battery for 160watts of lights that give me 6 hours a day?
czcams.com/video/TJBGbufexEM/video.html this video explains how to size your solar system.
For your case. 160w * 6h = 975Wh. Take backup storage as well. ie. 3-5 days that can power these lights during cloudy days. With backup, you would need total of 2928Wh.
Depending on what type of battery do you have. Lead/acid battery can only use half of its capacity while Lithum battery can offer 100% of its capacity. If you go for Lithium batteries, you could do with 2x 1500Wh batteries or 4x 1500w Lead/acid.
For solar array, as many panels as you get. To charge that amount, take that 2938Wh and divide it per hours of sunshine you get, that gives you an idea of how many panels you need. If you get 5h of sun on average, you need 2928Wh/5h = 585,6W. Bump that up to 800W as solar panels are cheap and thats probably what you need. 2x400W panels would be enough. ROUGHLY
For charge controller, you calculate 800W (Solar array size) / Battery voltage (Usually 12V) = 66,7 A for output. Make it larger for efficiency and safety.
soon we will buy 12v hybrid inverter, 150w solar panel and 2 16ah gel battery is this good enough
Thank you for your message. Please provide more background information to clarify your question, thank you.
Hi Respected sir.
Hello Imran, thank you for your reaching out. I received your message via the main website and have responded to it. Thank you, Jesse.
Respected Sir,
Let Suppose i have 3 Battery Banks, where each Bank/string contain 24 Cells (Series Connected) to make 48Volts, the Voltage & AH Capacity of each cell is 2V, and 1000AH respectively, and Further these 3 Strings are (Connected in Parallel) to make 48Volts and AH Capacity of 3000AH.
Please help me to calculate the following Parameters???
* The Power i need to charge these Battery Banks/Strings?
* What will be the Charging time of the whole Battery Array? Or how much time these 3 strings/banks take to charge?
* Charging Currents/Amps and Charging Voltages of the whole Battery bank?
* Which size of Hybrid Inverter would be used to charge the Battery Bank and Simultaneously run the load?
* Which rating of MCCB and Cables will be used for this battery bank?
* How many PV Panels i need?
Respected Sir, how i can calculate the above following parameters, waiting for your Guidance???
Imran.khan10603@gmail.com
I am looking for something deferential than that . I need batteries that I can charge it quickly in 4 hr with a lot of energy power take . and can give me 20hr time operating in the day with out electricity .
Example : I want a 2 battery 12v that can give me 25A in 20hr and I can charge them completely and safe in 4hr with 150amp 24v .
But I can't find such an ideal battery that can Handel that and can give me what I want .
Wait the C rate does not expect. As I understand 1C for 100AH battery can 100A in one hour. if 2C 100AH battery than means it can draw 200A 30min safely. Please help to provide more info to support the C rating.
Jesse,
It is saji. C 10 means it takes 10 hrs with 15 ampere current to full charge the battery. Since it 150 ah solar battery, it will be faster in getting charged. C 20 batteries are slower in getting charged. It takes 20 hrs with 5 ampere current to get this full charged. For my solar with 750 watts panels, off grid system i use both batteries. C20 battery was already with me. Since two batteries are of different kind in charging and discharging, whether it will be compatible? That is my question.
Hi Saji [is it Saji or Sajy? I am curious now]. Thanks for your feedback again, I believe you have suggested a great topic for a separate video. I will create this video and share it with you. Thanks, Jesse
I live in the Dordogne department in SW France. I have a swimming Pool with a 750watt pump. I would like to have that pump solar-powered. What set-up would I need to provide that amount of power? The house is mainly gas, so it is only the pump that I need powered.
I think that pump is probably too powerful to use solar energy. I mean, anything is possible with enough solar panels and batteries, but motors and heaters use the most power. So a motor or a heater is the most difficult thing to power with solar energy. You could power something like a laptop or a string of lights for much longer than you could power even a small fan which has a motor in it, or something like a hair dryer which has a motor and a heater. So, you could definitely power your pool pump from solar panels and batteries but it would take many many of each to be able to run the pump for even a short while.
@@OFR "motors' dont use much. What you say is nonsense. It FULLY depends on which motor you are talking about. It can be a 1 watt motor or a MW motor and anything in between. ALWAYS look at the power consumption. In general (and you are right wrt that) is that devices that are meant to produce heat, are the biggest users of energy. So that is:
Heaters (obviously), usually come in 1, 2 to 3 KW at 240V in Europe, bc our wiring and fuses are typically designed for and limited to 16 Amps.
P=U*I > 240*16 = 3840 watts, which is 3.8 KW. Those heaters were usually designed when we still were at 220, or 210 V in Europe, which is why they are usually 1, 2, 3 KW, but never more. 220*16 = 3.5 KW (you dont want to be at the top of the range as fuses can trip nearing it.
So apart from heaters; washing machines (2kw), dishwashing machines(2kw), Dryers (2kw), coffee makers (about 1 kw); microwaves (700w); etc. ALL these machines heat.
Lower usage is: Fridge (cooling is by pump) about 100-200w. Freezers (same); computers, stand alone (100-400), laptops are loaded by device, but typically as they are designed for low power usage, 30- 100W. Electric tools; 100, to 1000W , or even higher depending on heay duty. Smart phone loader; couple of W. Lights, led savind type; 1 - 10 W. etc etc
So motors do not use much. A laptop also has a cooling fan, which is a motor, yet uses little energy.
Let me start by giving some general advice and information:
Im guessing you have it connected to the mains now and decided 750W is quite a lot to have continuously running and with increasing energy prices (not by Putin, but by our criminal govs) it might be wise to put it on solar... and thats not a bad idea.
However, 750W is no small amount. Consider that your microwave is typically 700 watt at max power, which means you have a microwave at your pool that is continuously on...
So in general, you should consider this:
Did you buy a pump that is too big for your pool? Im guessing you didnt. Then the next question will be; Does it have to run continuously? I dont think so. Obviously your pump is pushing or pulling the water through a filter, to keep the pool clean. I cannot judge wether or not your pool is easily dirty or not, so youll have to judge that yourself, but i am guessing it doesnt need to be continuously ON. You can have your first moneysaver there!
You might want to calculate the pumps debet (amount of water pumped per time unit) and see how often it needs to pump all the water in the pool.
So, an example:
A typical 500 W pump does about 10 cubic meters of water per hour. It will be less if you have a packed filter unit, specially if its clogged up (always make sure the vents are open!), so lets say you get half of that; 5 cubic meters of water per hour. If your pool is 4 meters, by 3, by an average of 1.5 meters depth, that is: 4*3*1.5 = 18 cubic meters of water.
That means that the pump will have filtered all the water in the pool in about 3.5 hours. 24/3.5= ~7 times the entire pool per day if the pump is continuously ON.
Now, do you need to filter that much? Most likely not. I think i would be completely satisfied with filtering all the water once per day. Ofc that is a theoretical ALL water, as the water isnt taken out entirely and put back in, so it dynamically mixes, but seems reasonable to me.
Lets assume you want it twice per day. That means your pump can be off more than 2/3 of the day! So only on 1/3 of the day. You can simply put a timer on it and immediately lower your cost by 2/3. And that will also make the solar setup a lot more doable...
So, suppose you want to have continuous 750 W power.
That means you will need 8 solar panels of about 1m * 0.5 m to power that. And even worse, that is at maximum energy gain from the panels, which you will not have all the time, and definately not at night. So lets say you need to increase by 1/3 at least, to compensate for lower output and add another 1/3 for nighttime when they bring you nothing. That means the very minimum of ~14 solar powers to even come close to a continuous delivery of 750 Watts...
14 panels of 0.5 m2 is 7 square meters of solar panels... Thats a bit much.
Actually at present, it is very much, now that we are continuously faced with higher energy prices. Just to give an idea:
Your pump, if it is continuously ON, uses 750W/h, which is per day 24*750W = 18 KW/h per day. The price of 1 KWH of energy, in NL (dont know the price in France, which has a load of nuclear plants, so maybe cheaper than NL) is about 50 euro cents. So you are paying 9 euros per day for the pump. That is 9*365 = 3285 euros per year for your pump. quite an amount and i would definately not be able to afford that. But maybe you are ;]
Still, its quite an amount even if you make 5k per month. Right?
So lets assume you decide to cut back on pump use and install a timer on it, as said, that only switched the pump on for 1/3 of the day.
Well then the cost immediately goes down to 1/3 So the 3k plus euros becomes 1k per year. And the pool probably looks just the same.
So lets suppose you want to solar power for the 1/3 ON situation:
Then you still need a bare minimum of about 5 solar panels of 0.5 m2 and i would definately go for 6, minimum. So 3 m2 of solar panels.
Then we get to the amount of batteries you need:
So you need 18 kWH, one third of that in energy storage (see above): That is 6 kWH of storage, bare minimum, which will allow the use of the pump with 1/3 of the time on, for 1 day. That means if you have a week of cloudy weather, the batteries will not be charged and wil be run dry, as the pump still wants that 6 kWH per day, while the solar panels then only deliver maybe 1/4 of max.
So:
A typical car battery is 12V at 40 AH (small to medium size car battery). Which means it can store 12*40 = 480 Watts of energy.
To get to 6 kWH, you will thus need 12.5 car batteries, to power your pump for 8 hours for one day...
Even that doesnt look like an attractive option. And to have it run continuous you would need 3 times that, and still will only be able to span 1 day of practically no loading bc of very little sun. Which is 37.5 car batteries.. ;[
So, you would either have to up the number of solar panels a lot and not store the energy at all, but directly power the pump (with some electronics added) , or limit the pump greatly and go for storing and a regulater amount of pump/filtering.
I think i would go for this:
Directly power your pump from the solar panels. Ofc you do need a solar regulator, which isnt expensive. And a converter to 220V, which is also not expensive. Then you will need those 8 solar panels of 0.5 m2, so 4 m2 of solar panels, to get to some 800 watts at max output of the panels. And skip the timer. Maybe go for 5 m2.
What then will happen is that the pump will be powered whenever the panels deliver enough energy. So if the sun is shining in summer, the pump will be running, but early morning, it wont and in the evening it wont and when a dark raincloud passes, it wont. Obviously not at night aswell. That will provide enough pumping in summer, when you have plenty of sun in France.
It MAY mean, but you'd have to check the electronics, that the pump will ALSO run if the panels do not give enough energy, but it will run slower. That would be optimal, but it depends on the electronics and pump if it can handle it all. I think it will actually. You cant 'draw' too much from a solar panel, as there is no draw, but a push of energy. So they will keep voltage up, but with limitied Amps. The converter should also be able to handle it. And the pump will imo. Normally to have speed control on a for instance drill with variable spin, it limits the voltage, which reduces the rotation of the motor and reduces the amps. But if you reduce the amps, it will also spin slower, while maintaining voltage.
I hope this helped.
To make it a whole lot easier, i think you should consider puting a timer on the pump, and limit its filtering to 1/3 or 1/5 of what it is now. That saves you a lot of headaches and money and your water will most likely still look just as clean as it is now. Bacteria build up will also not be a problem, unless you get pool parties every day with 30 people in the pool.
And it costs some 20 euros for a decent timer, at most.
Good luck!
Lithium is too expensive and AGM batteries are cheaper but won't last more than a year in hot areas. Flooded batteries seem to be the best bet for me as I have tried . Yes flooded ones can't be fully discharged but they last up to 6 years if maintained properly . I have six C20 185aH batteries
I was able to use agm.s for over 2 years at the equator and they were in close to brand new health at the end of that time so I think they do fine in hot weather.
is there any battery that is better than tubular battery?
Yes, Lithium Ion batteries but way more expensive than tubular batteries.
Dont you mean at 3:15 that it should be C 0,5 for emptying in two hours. You take half a Capacity in one hour. Lipo batteries got very high C rating, like C40,60,80 and even C100.. indicating they can deliver high amount of power and literally drain the battery in minutes.
how many 12. wolt battery can you use for 12 /350 wats solar panels
You are asking the wrong question. How do i explain this...
Your panels can produce at max power; 12 * 350 watts = 4.2 kW of energy. Note that there is no time in that number. It is the amount of energy, your panels can deliver at best performance. Obviously, usually lower, depending on sun and other.
So now you are asking how many batteries you need. Well, that completely depends on what you want to do! A battery does not create energy. It merely stores it...
Let me translate this to something visible.
Suppose you live at a small water stream and you throw in some hoses and let the water flow downhill, through those hoses.
Lets say you have 12 of those hoses in there and each hose gives you 35 liters of water per hour. (i take your numbers a bit, but decreased the hoses flow by factor 10, bc thats more realistic). So your total anount of water you get downstream at your house, is 12*35 liters = 420 liters per hour. I dont know what you want to do with all that water, but hey, its your house and your example ;p
So now you are asking, how many buckets do i need? Because the bucket is the equivalent of that battery. It stores water. Where the battery stores energy.
So how many buckets?
Well, that depends on what you want to do with that water. Why do you want to store it? And how much do you want to store?
Suppose the stream doesnt flow for half the time. Thats unrealistic of course, but suppose so.
And suppose we dont have 12 hoses in there, but just one. So that gives you 35 liters of water per hour, downstream, at your house.
Hmm thats still way too much for an average family. So lets assume it is a factor 10 smaller. It is a very small hose... and it gives you 3.5 liters/hour, so 84 liters per day. Thats far more realistic.
Suppose on any given moment, you want to water your plants and need a bucket full of water. Thats 10 liters. But you only get 3.5 liters per hour and you dont want to stand waiting for 3 hours untill the bucket is full. Also, you may want to shower tonight and you will need 2 buckets for that, at least.
So you want to have storage for that water, for when you quickly need a lot.
So you can then calculate, what you will need, taking a maximum you are going to want at a time. So lets say your shower is the biggest amount of water you will use at a time; 20 liters.
Then you need a system that stores at least that amount. So you place 2 buckets. But since you may want to water the plants right before. And you may want to cook right after and clean a few things, you will need to buckets more, for top amount of water used, that should be available at any time. So 4 buckets.
You should regard batteries the same way.
What is the maximum amount of energy you are going to need at a specific time?
Suppose you have a 2kW waching machine. It uses an amount of water and heats that, which is what takes most of that energy. Max draw of the washing machine is 2kW and it runs for an hour, so it uses maximum 2kWH. It will be far less, about 1 kWH, as it is not contantly heating of course. The motor uses far less.
Considering your setup of 4.2 kW, it nears one group of a regular house in western Europe, so you were probably thinking of that. Being able to run all your equipment normally, as you would being on the grid. So capacity wrt that is good.
So now you established your max use.
Now you also need to determine your average daily use. In kWH. You can see that on your electrical bill; what you normally use on a daily basis.
Now you should also consider that you use batteries to span a day of little sunshine. You will never be able to span a week, or more of energy storage in batteries, with normal use of energy. So it is limited to about a day. And far less in winter, depending on where you are, further north, further south, and other.
So
for that spanning of 1 day, it completely depends on your average daily use. In my situation, but i am very 'cheap' i use 2 MW per year.
That is 5.5 kWH per day. (and i dont use electricity for warming the house. If you want that, you will need a LOT more)
So for my situation, if i want to span 1 day without sun, i would need battery storage worth 5.5 kWH.
A typical car battery for a small to medium car is 40 AH at 12 Volts. P (energy) = U (volts) * I (current), so it can store 40*12 = 480 Watts.
So in order to store for a day, i need 5500/480 = 11.4 car batteries to last me one day without sun.
Now, hoping it will never be a day without any sun, or better, without the solar panels giving nothing at all; you might got for average energy delivery from the solar panels. Suppose they give 20% even in winter. And 50% in summer on average.
Then your panels will still give 4.2 devided by 2, bc they wont give anything at night and lets not count early morning and late afternoon aswell, so half; is 2.1. And it is not a sunny day, as were talking about, again half, that means you will still get 1 kWH that day.
You can subtract that from your average use, which in my case is 5.5. - 1 = 4.5 kWH
Divided by 480 watts (1 battery) = still 9 car batteries i would need.
In winter it will be worse even, so maybe just 20% of 2.1 = 420 watts. > 5.5 - 420 > ~5 > 10 batteries.
I hope this helped. Good luck!
alot!
Can you analyze Tesla batteries
Hello Tom, thank you for your question. Excellent suggestion! I have a video lined up about the Tesla Powerwall: I assume this is what you are referring to, is that correct? Thanks, Jesse.
Those "CYCLE vs DOD" charts are for *ESTIMATION* *PURPOSES* *ONLY* !!! - ie use them to compare two batteries from the SAME manufacture, but be very cautious when using those charts to compare batteries between two different manufacturers. You should NOT expect to get as many cycles in the real world. Those charts do NOT include any "Calendar Aging", you cannot simply extrapolate from 2,000 lab test cycles into 2,000 days, when their LAB TESTS were done in a few months
Thanks for sharing your perspective.
So rule of thumb. Dont drop batteries below 60% and greatly extend their service life
Good video explaining basics, but while speaking about power, you said watt hours. Actually power has watts as units. Watt hours that you mentioned in the video is unit of energy. V * I results in watts and not watt hours. I will come back to this video whenever I need to remember some basics. Thank you.
It is good to hear you enjoyed the video Ram, and thank you for your contribution!
Lol 😂
Power is the RATE of using energy so it's per time ⏲️
hello
we have lifepo4 lithium battery with bms.
we put into use 5 days ago
it has now 24 cycles, eventhough it never got under 90% until now
is there any explanation ?
It means that you discharged & recharged it several times in a day. Probably you have put a DOD of maybe 50% on your inverter which is less for a lithium ion battery. They can be discharged more than 95%.
@mirchichamu: I just wanted to give you a thumbs up for the valuable contributions on the channel! All the best, Jesse.
How is it possible that SOC + DOD = 100% ?
solar Battery you must know before you buy
I recently watched a video of a guy making a claim that deep cycle lead acid batteries (golf cart batteries) will last forever if you maintain them. He then goes on to explain his maintenance schedule where he tops the batteries off with distilled water, and attaches each battery to a welder as his charging unit. As he charges the cells for five minutes, he judges everything by the amount of bubbles, and that if there is a cell that does not bubble, he simply keeps charging in his intermittent cycle by adjusting to voltage. he lets the batteries rest for ten minutes, and continues his five minute charge increasing the volts (but never over 200v). Is there any truth to this?
Thank you for sharing this story on the channel Elmer. Very interesting! To answer your question whether there is 'any truth to this': I would definitely agree with the importance of maintenance and electrolyte monitoring. Once any of your cells 'runs dry', you have most likely permanently damaged that particular cell. I can also give credit for the individual monitoring of cells, whereby the visual clue of gassing in a particular cell tells something [but not everything] about the State Of Charge and overall health of that cell. I am not sure what other positive feedback I can add, though it would be great if someone would have figured out how to make a battery last forever! Good luck with your research, all the best. Jesse.
💥💥💥What battery is your favorite for a solar system 💥💥💥 should I use 6 Volt GOLF CART BATTERIES 💥💥💥
Hello Susan, thank you for your question. My favorite battery for your situation would depend on what your system requirements are. The 6V golf cart batteries often provide for good lifetime and financial efficiency for small to medium sized systems. Good luck with finding the best one for you! Jesse.
I think he's a Skynet T800
Haha you got me!
Sometimes I feel like you and I are the only people who feel like lead acid (and I use classic flooded lead acid) are the least expensive battery solution even over time. The lithium needs to about halve in price yet. And no one thinks about how it will be if their batteries fail. For my lead acid I just go visit my retailer and exchange them, no questions asks (had to do it once when I screwed something up that I'll keep secret).
Hello BearChow, thanks for your message. It does indeed seem like the general consensus is that Lithium batteries are the obvious choice over Lead Acid batteries. Let me just respond to your message by saying; thumbs up for your critical thinking! Flooded Lead Acid is still installed in large grid-tied and off-grid energy systems, which is unlikely to change in the near future. Lithium batteries feature incredible performance improvements compared to Lead Acid batteries, and often make sense depending on the design criteria. Now that I am typing this message, I am considering sharing a more in-depth video to separate the Lithium 'sales-pitch' information from the facts. You might also be interested in some of the videos I already shared on Lithium comparisons, here is a playlist I made for you: czcams.com/video/JeVakJhwkis/video.html. Enjoy and all the best, Jesse.
@@SolarSolution Thanks. I will agree that if you ignore cost (short and long term) that Lithium clearly has technical advantages. There will come a time when the advantage is clear. I eagerly await that day.

The best solar panels for Sudan
Hello Garipalla, thank you for your message and question. I have shared a complete video on solar panel selection, called 'The PV Buying Guide'. It think this will useful for you, I will share the link below. Enjoy! Jesse
czcams.com/video/TB7FfgsVn1g/video.html
Try to buy any solar panels which are A+ grade & tier one. Usually they are verifiable online.
The best & relatively cheap options are Jinko solar, JA solar, Longi and Canadian Solar.
There are others like LG and Panasonic but they are more costlier than the Chinese brands.
Cost sorry
Ok thanks.
I am using 24v settings can you tell me what to set my controller on for hi voltage and low voltage and float voltage for lithium batterys
