You're always so good at thoroughly explaining everything! And making it look so simple. Thank you, Jason.
Very good video. I built a 12 volt system like this about 2 years ago using a cart from Harbor Freight. Makes it nice to be able to just roll around the diy solar power station.
I built a system very similar to yours but I used a cart made of composite material that is non-conductive. I enclosed the battery storage shelves with chalkboard material bought at Home Depot for under $10 each. I cut them to cover the sides and back of the open areas pf the cart. I secured them to the cart with strong Velcro. This will prevent items getting into the battery area.
I do not have insulated tools, but I do cover the tools I am working with in heat shrink tubing.
Thanks! Hi - I wanted to thank you for all your help. Thanks for being a team builder! I have learned a lot and it has saved me a lot of grief and dollars!
Thank you so much, Katy!
love the cart setup. an alternative to the resistor is to put a filament light bulb in series on the positive lead when connecting the battery. also there are a lot of 240vac output ups solar inverter chargers. to use one of those you'll have to add a split phase or center tap transformer, but you can get from the ac output lower amperage while delivering the same amount of power.
I'm just getting started in my solar journey and I am looking for informative videos. I like your presentation style. It moves fast, covers the subject well. I appreciate the matter of fact approach. You speak clearly without stammering or pauses. I subscribed and liked. Well done.
Glad it was helpful!
Love the setup, definitely a life saver for any emergency...well explained great channel....!!!
Great build on the modular setup. Power stations are great but these can be fixed or parts swapped and more. Great for the person who likes to build there own..👍🏼
The sparks 🧨 were great to 😅😉
Totally agree! Upgrading or adding batteries is EASY with a setup like this.
wow.. thanks for the tip about the resistor.. really appreciate it.
I own two Bluetti AC200P's, Echoflow Pro, and an off-brand 2000 watt solar generator plus I have 2820 watts of solar input. My solar generators are usually fully charge by around 12:30 pm. I live in Golden Valley, AZ with around 300 full solar days per year. I have excess solar charging capacity on most days. I like to tinker around with stuff. So, this gives me some ideas for my next project. Thanks for the video!
NICE! Rule #1 Nothing is EASY! Some suggestions for safety IMHO to prevent a fire (these things HAVE caught Fire). HEY! it's YOUR home. Think AC panels here. A Main disconnect switch of the proper size at the source (that big battery is the source here). THEN a fuse or breaker of the proper size to carry your load and protect the WIRING within 7 inches of the battery POS post (REQUIRED on a commercial unit I believe). Do maintenance checks often and keep connections clean and TIGHT. Could it pass an inspection? HEY! WHAT CAN GO WRONG? Insurance have disallowed claims because of these things. Do it RIGHT don't just make it work!
Very informative. The fan noise would quite down if you hung the unit on the end opposite the handle thus having top to bottom airflow. That would also free up the top shelf.
Thank you for sharing. I am looking forward in creating my own system.
Hi Jason, I really love your canned food setup in the back. Looks like it's setup so you can see the dates on all the cans.
I made a video about it AWHILE back, you can see it here: czcams.com/video/hSZ0Hh3urvM/video.html
Nice project and well done video. I really like the concept. Since I already had a 24 V home backup system using rack mounted batteries and Victron Multipluses in split phase mode, I didn't need the inverter. So I just built a 24V battery bank on a three tier cart using 2S3P x 12V 230AH TimeUSB batteries which provide an additional 17.6 kWh of battery capacity for about $3,000 including the cart, bus bars, breakers and cabling. I plug it into my system using 2x175A anderson connectors and 2 x #2AWG cabling.. It works great and has become a permanent part of my home backup system. One additional item to consider when putting 12V batteries in series is to make sure the batteries are all top balanced before hooking them up and add a battery equalizer to keep the 12V batteries balanced over time.
Another great job and video. Thank you for taking the time and sharing the info. God Bless.
Stand your inverter up cause heat rises and it rising up into the electronics whilst laying on it back. Great idea and I love that you didn't hide the prices like most people do. I'm looking to do this with a 5kw 240v hybrid growatt to power my house as I'm exporting 20kw a day back to the grid yet still have to but power everyday .
What a great tutorial and super neat build. Really interested in that transfer switch and glad to see you also have a video on that. Will be watching that next. :)
Cheers from Chiang Mai, Thailand.
I used that same cart for a build I did about 4 years ago using Tesla modules. 👍
This is a fantastic video. The info you presented was just outstanding. Very good learning
Thank you very much!
This is one of my favorite diy build videos. Well done, thank you. I'm jealous of all your backups btw. Subscribed, bell rung, commented, upvoted, liked, shared ... may the algorithm gods smile favorably upon your channel friend.
Thanks! :)
Nice informative video. Thanks for sharing and giving us lots of details on this.
Great video, I just made a video with my slightly upgraded setup, still 12V... i want to go 48V soon. your video helped explain some of the aspects of it. thanks!
What up Doe!?
I really like that all in one setup with adding 4 batteries Dr J'
👍🏻👍🏻
Awesome video. I wish I seen it sooner. I’m now to far into my 12v system to make the switch. No pun intended.
Very great build
Quick background, im a marine electrician, and design and install systems on boats like these
One thing i would recommend is using a class t fuse for the inverter
We’ve seen anls break and then re-weld themselves back together and cause a fire
But beautiful system!!
Thanks for sharing your experience, that's helpful!
Excellent video as usual!
Excellent thanks Jason 💐
Thank you! 5ohm 10 watt resitor those huge sparks are always adrenaline dumps😊
I like the thinking outside the box. We have come to be reliant on plug and play, if a single device i.e. solar generator fails, or your generator fails, you are SOL, this has its place. Single items can be replaced to restore the system. Having said that, I am a huge bluetti fan, I have AC200max with 2 b230 batteries. I have 2 EB70 and 1 EB55 in 220v versions. I have spare cables and spare power supplies. But always looking for other ideas. Great video thank you.
Excellent video. Great information.
I think it's totally awesome!
Very nice! Thank You!
Awesome video
Thanks for checking it out!
Agreed 😊
Agreed!
Great video on "Energy"! As an outdoor enthusiast and RV lover, I highly recommend checking out the Segway Portable PowerStation Cube Series. With its massive capacity, fast recharging, and waterproof technology, it's perfect for powering all your devices and appliances during camping trips or in case of a power outage. Plus, the Smart APP Control feature adds convenience and peace of mind. Definitely worth considering for your outdoor adventures!
Great video!! Awesome idea! I am going to copy your system. Thanks for sharing your build!!
You are a great teacher....
Thank you! 😃
Nice one bro
Good stuff 👍
Hi, thanks for the sharing, I have a couple of questions:
1. Can it run my A/C unit on 220V?
2. How many hours it runs at 3000W?
3. I want to build some similar to run automatic when I have power interruption from the grid and keep it charged with the grid not solar (for now)
Excellent video. I have a Delta mini but I think I will build one of these also because I can always add additional batteries later on.
Glad it was helpful!
all in ones are for sure the way to go when it comes to solar input and battery storage cost
if you dont need to be mobile.
I agree, it's super simple to put together! This one is KINDA mobile with the wheels, but nothing like a portable power station haha.
Wow, this is almost what I'm working on in my basement! I saw Survival Lily use a cart in a video a while ago, which I thought was a wonderful idea, and now you. 😁For what its worth, on mine I am using 4x 100Ah batteries that just fit on the bottom shelf. (I used a piece of 1in thick insulation board under the batteries to cover the screw heads for the casters and the ends of the screws holding the uprights.)
Four 100ah batteries is probably the best way to go, then you can pull the full 3000 watts.
Great video! Was looking to something similar l but with the MPP 2724, but I can see the versatility of using a system that plugs directly into a transfer switch.
With a system like this you can take it with you to the next house :)
Question so the power coming out of your inverter is only supplying 120 volts to you transfer switch am I right. If not how did you wire the the connection in the transfer switch box. Why didn't you ground the output from the inverter. Thanks
Older video I know, but... Could I tie two of these inverters together for split phase 240?
I understand this can get complicated... Just wondering if this inverter can do that or if you have a suggestion on a different one to accomplish the goal of a similar cart build but that can provide 240 (split phase). Thanks for the video and simple break down.
I just installed a whole house 26kw NG generator with ATS and am interested in adding a whole house battery pack to sustain for 3-5 days. When batteries are exhausted generator starts, recharges and then shuts off. How do I determine my battery needs for whole house application?
Excellent ideas. Nice to DIY and have a purchased solar unit. Caution with the metal cart 💥
Short circuit = BOOM! haha
Can you connect the ac output to the wall plug to run all the house power
And also connect the ac input to wall outlet to charge the battery when the power come at the same time ?
Great Video Thanks Jasonoid!!
Glad you liked it! Something like this will work great for grid instability.
awesome build👍
Thanks for checking out the video, Mike.
I love the Rack to the Right with the Preps. I see your Prepared. I have a similar setup myself
I was thinking of doing a simple preparedness video. It's good to have food, water, supplies, and energy stored up :)
@@Jasonoid you should, the same kind of people interested in Battery backup will probably have a backup of food stashed away. If I had the means to make a Solar Powered Emergency Bunker I would, lol
@@Jasonoid I have a room in my house I don't use, every time I take a trip to the store I get a couple extra things, little by little without making it look like I'm hoarding
@@Moes_Prep_and_Tech that's the way to do it!
Cool idea, however your fuse amp rating needs to be smaller then the amp rating of the cable. Also solder on cable going under a screw isn't good practice. But well done and good work.
Seeing that you are going to a transfer switch, do you have the neutrals from invertor , line and load tied together. Bonding of neutral and ground at main line panel only. So your inverter should be a floating neutral , not bonded.
The rule being bonding can only at one place only .
Oh, one more thing...I create insulated sleeves with heat shrink tubing. I tape off one end with electrical tape and then I slip one each over the pos and the neg lug. I use a tubing diameter that is snug enough that it will not fall off.
I really need to upgrade my system to LiFePO4 batteries.
I've got a similar setup attached to 2 160W solar panels. Two 115A/h AGMs, a controller/regulator, and a 3000W Pure Sine wave inverter. I feel like it needs more battery capacity because I can lose 10% of my charge in an hour or two in full sun on the two parallel-connected batteries when running a computer, TV, stereo system, a 75 litre dual zone twin-lid camp fridge, a phone charger, and some LED strip lights. I'm wondering if I've set up an inefficient system. Both panels are connected in parallel as well. Maybe I'm expecting too much from the setup, I dunno. I can run the fridge by itself overnight after an hour or two of using the computer system setup, and it only drops to 48/50% . I need to rethink my computer setup though. It's a desktop using a 100cm Tv as a monitor, and a Sony stereo system for speakers. A lot of power just to watch CZcams and catch up with news and social media.
Good thing I have a ULP genset as a backup I guess.
Awesome!!
Great video and I've done a similar setup with a cart in my garage so I can bring power where I need it in my driveway. If I would do it over again, 48v all the way.
Yeah, 48v system with server rack batteries!
@@Jasonoid like you, I wanted to use what I already had on hand and it worked out. 48v would be ideal just from a wiring perspective, especially with the array you have in the driveway.
My setup I made in 2016 uses 4 6v 260Ah AGM batteries (Renogy) due to costs of lithium in 2018. A Renogy 2000w pure sine wave inverter/charger, cables, breakers, and fused properly. An Epever 40amp solar controller, MT50 monitor on an 800lb Gorilla cart. I can grid power, generator, or use the 800watts of solar panels. Tested and routinely used as UPS.
Great setup! That's a lot of power right there!
Thanks for your video, great as always. Wondering if you could do one explaining the pros and cons of 12V vs 24V vs 48 and break down where it would be most beneficial.
Great suggestion!
48 volt is more efficient than 12 or 24. The more voltage step-up the more power is used just for the step-up process. When using a 220 split phase inverter to power central AC unit or other 220 appliances a 48 volt system is pretty much a must.
@@equanimousawareness If all your doing is keeping the fridge running, 12 or 24 volt is better since the inverter doesn't eat as much power sitting around waiting till it needs some energy output. The 48V split phase eats more power if the AC doesn't turn on.
What is the durability of this set up? How often would you need to replace things like the batterys and inverter? I mostly want something like this that i can use as a power source during emergencies so i don't have to run my generator all day and night.
There was no comment about the transfer switch wiring, normally they are wired for 240 split phase, but your invertor was 125V...I know the teansfer switch can be wirred as you want, but I did not hear that mentioned.
do you know of any software for the communication that will work for this inverter. i built the same sort of setup
Thank you once again. 👍🐝🌞
You are very welcome
I've got the same system, except for the batteries. I have two 300 ah 12v power queen batteries. The same sungold 24 volt system. Will see how it works.
Looks like the one silver Stacks Prepper made. Nice 🙂
I haven't seen his channel before, I'll check it out!
NICE!!!!
I bought the 24v kit. The issue I have run into is delayed shipping. They didn't inform me most of the kit is in background. The other issue I ran into is I did manage to get it put together and the batteries won't charge. Tech support is really slow to respond.
Any chance you could do a current remake since prices are cheaper. I'm looking at doing this for an emergency system (with Victron items) Love the videos as always
It’s a floating neutral device, which is good because it will ground to your house via transfer switch. You don’t want 2 ground points at once
Great video and I love the cart idea! What would you say are the main advantages over this system vs a Delta Pro? I know what the retail price of the DP is but they routinely go on sale for close to this systems price.
Will made a similar video and compared it to the DP Pro, I watched it this morning.
czcams.com/video/fdeZz4QvxG0/video.html
👍👍 good vid, thanks.
Thanks for watching!
This is great. I was just talking to Ask Ive Solar about a very similar setup as an alternative to a powerstation. Though it was using an EG4 version of this and server rack batteries. Did you consider the structural foam carts? They are the same though they might not have the middle shelf.
I like that a system based on an all in one tends to have a lot more charging amps, wider voltage range, and programmability. I am trying to figure out home assistant right now so I can make my EG4s turn on AC charging when the forecast and my weather station confirm poor sunlight.
I think for someone looking to build a 'future proof' DIY setup, 48v is the only way to go. I LOVE those 48v LFP server rack batteries! Eventually I want to have a system like that in my home, it's just a fairly large investment. Adding a smart capability would be really cool!
Just make sure you purchase UL listed components since those items have been vetted for safety in your home.
Enjoyed your presentation and certainly a modular, DIY approach to home backup power is in many ways superior to off the shelf products. I forget, was there a monitor for battery SOC in your set up? For camping (and home backup), I built a 12 V 100 ah battery with MPPT charging, various connectors, a charger and a small inverter and find that an EcoFlow Delta 2 does the job better in a smaller package. However, if anything goes bad on the Delta I can’t really know what has gone wrong and will have to wait weeks sending it in for repairs, etc . With a DIY unit, you have more options. Did I mention I really enjoy your videos?
Thanks Jack! The SOC is kinda tracked in the inverter on the screen... It's not amazing though.
I think the portable units have their place, the Delta 2 is so lightweight and compact. It certainly is one of the best current options for a 1000wh device. I personally enjoy DIY and off the shelf options because both have advantages.
Tear downs are good. You really do need to see the quality of the build.
One thing I would be a little weary of though is tinning wires before putting them in a compression style connection like that. Probably will be fine though. Nice video!!
Thank you, I learned that after posting this video.
I bought a 20 amp plug in charger for my big 300ah battery and I used it with a 2000 watt inverter to power my microwave during a power outage. It was also nice to know I have multiple sources of power when the freezing storm with high winds hit n December, especially for my electric blanket. The wind chill was below zero and the power kept failing. Of course the new electric blankets are digital and so are the heaters I had here, so they don`t turn back on when the power goes out for a few minutes.
So I plugged my electric blanket into one of my Bluetti EB70s. I accidentally put it on medium high instead of a lower setting when my foot hit the control switch but only used about half the battery during the night and of course it stayed on. I ran my WIFI and lights from batteries too. My 600 watt manual heater was at my sister`s house since it`s "too cheap" (I`m so dumb, see) so my nephew refused to bring it. I had to use the horrible and way overpriced digital job that`s 1500 watts and is either too hot or too cold and has to be turned on and off every few minutes and turns off when the power fails. It would drain my battery in a couple hours.
So more and more I appreciate having these backup batteries and even have seven various low wattage cookers now that work with them. Six of my cookers work fine with my 500 watt power stations too, and two can be used with some of the smaller ones. I was born in the mid 1960s so these things are like miracles to me and I will never stop being amazed by this technology.
Glad your backup batteries and inverter are working well for you! Have you built up any solar charging yet?
@@Jasonoid No. I`m ordering another 190w HQST panel next month and the bolts to connect the 200 amp fuse to the inverter cable and some switches to be able to disconnect the panels and battery. After that I`m getting one more 100w panel to have four of those in series/parallel with the two 190w ones. Later I`ll either get two more larger panels or two 100w ones. I`d prefer the larger ones but the cost is higher. I need to get two 100w mono panels. My others are poly but the 190w ones will both be mono. The good thing is in a pinch I can dump power into the large battery with my two EB70s and my two 500 watt power stations with the 20 amp plug in charger. I need to learn how to do this with their 12v ports but they only produce about 100 watts.
I`m thinking of getting some cheap MPPT charge controllers to rig up for this. Not sure how to go about it yet though. It would be nice to have that option if needed. I can dump over 1500 kwh into it that way to extend run time. But I also want to be able to get the big battery back up from a very low state of charge at night or on a cloudy day if I happen to drain it too low. I think the higher priced Renogy 500 amp battery meter will prevent that. There`s a less expensive one but it may be more difficult to use and may not be worth the 20 bucks less. I want an accurate meter to avoid surprises.
Love this setup. Would you consider doing remote consulting for a fee to help me on a similar setup?
Thanks!
Thank you so much Erik!
The Danfoss BD50f compressor, for refridgeration, can operate in any power source, it requires 109 watts to operate. You need to purchase the Power Module for your voltage needs, 12/24v, 115v, or 220v.
The Power Modules contain an inverter, transforming the input voltage to the requirements of the BD50f.
If you have a 115v refridgerator with a BD50f compressor, you can swap Power Modules to the 12v version and run the refridgerator directly from batteries without an inverter. Therefore, more efficient battery usage.
That is good to know!
Standing up the inverter will allow maximum cooling. If the fans on the bottom are sucking air in and the vents are on top, having the unit upright will keep the unit cooler via the chimney effect (heat rises).
It actually pulls air in from the sides and shoots it out the bottom. The fans really move the air so I don't think it laying flat is an issue at all. The air coming out is always cool.
💘💘💘💘💘💘. Love your presentation. Thanks
I happened to be watching while on Bluetooth to my home theater receiver with Klipsch dual 12 sub.
When you connected the battery to the inverter, the floor shook🎉 😂
Heck yeah! LOL
I'm going to have to try that out, watching on my phone, but have the same Klipsch sub! It's a beast.
Always surprises thinking something is going on outside in real life 😂
I've always liked the component systems. I guess this is a hybrid component system. I am impressed. Are you going to put the add-on WiFi connection on it? Great concept of the HF cart. Thank you for a very good video Jason.
Thanks Kevin! I like how it has the option for the WiFi module and I have thought about adding that for convenience. I'm just hoping this project is an idea bed for others looking to do the same thing.
Really great video! Very helpful!
Can you use circuits from both 120 volt legs of your house 240v system or is a Transfer Switch limited to just one leg?
You can have both 120v and 240v transfer switches. You can connect to either leg. I have circuits from both sides. Reliance Controls has some really great videos on them on CZcams.
I am in the middle of doing this setup. My question that i have is, the inverter has modes for solar, battery and mains in terms of supplying power to the transfer switch. How does this setup handle MAINS from the main panel going through the inverter and back into the transfer switch? (A scenario is when the power comes back on but your battery runs low so the inverter switches to mains power). I am concerned that having the inverter powered by an outlet will cause an issue because of the neutral not being switched. So do you randomly plug into the wall to charge the batteries and then unplug and wait for an outage or do you leave it plugged in?
Hey Blake,
When you are running an appliance off of the inverter and transfer switch, that circuit is completely isolated from the grid / mains power. Plugging the All-In-One into an outlet to charge shouldn't be an issue since both are completely separate from each other.
I didn't see any issues while charging from the AC wall power at the same time as powering appliances off the transfer switch. Just FYI, I currently use solar charging as my priority and I haven't done a ton of testing with that function yet.
How would this be using in a van?
Hi, thanks for the video. Do the Power Queen batteries have low temp charging protection?
The cheaper model doesn't, but in a house backup situation that shouldn't be an issue. It would take a bit for the house to get down below freezing.
For another budget brand of battery that pulls full capacity, can be connected in series AND has low temp charging protection check out this battery: czcams.com/video/dd1W8_tdl2c/video.html
Hi Can you charge from ac and same time use transfer switch like UPS for your fridge or pc , great video thanks
Yes, this supports UPS functionality
I was wondering how you wired your transfer switch. The inverter output is 120V AC. So you can't wire with 120/240 split phase. Did you just use a jumper off the hot to power both bus bars with 120V? Seems like that is the only way be able to use all six breakers. Thanks.
It's a 120v transfer switch. All circuits are powered by one 120v leg. If it was a 240v it would require two hot legs. They offer many different models.
Great video! I just recently found your channel and have really enjoyed your clear and concise presentation. I am really considering this sungold inverter. Quick question- how big of a battery bank can this take (e.g how many amp hours)? Thanks!
As big as you want! I had 400ah connected before and it worked like a champ!
I have a 2000 watt backup power battery sold by FF Power. It has several 110 v outlets. I'm wondering if I could plug from the 110 to my transfer box, cutting most of the breakers, and run "essential" appliances overnight (sm. space heater + refrigerator)? All I'm tryijg to accomplish is avoiding running the generator (10kw) 24/7 when the power goes out.
Yes, you can run your transfer switch off your 2000w power station. You just can't pull over 2000 watts total.
hi i want to use this diy technique to power my rv using the 50amp plug that I usually plug into the camp site power pole.. is this possible? similar to the new power banks that can do that example: oupes mega 2 , 3 and 5 .. thanks
You'd just need to connect an adapter thats compatible with your connection. I don't see why it wouldn't work.
I am planning to do a similar 24V home backup setup using a transfer switch and possibly the SunGoldPower 3000W Charger Inverter. I have been reviewing videos to understand how to setup a home backup system and I am getting close. I have two questions.
The PV input voltage to the charger inverter states that the operating voltage should be between 120-400V. I understand that the VOC of the PV array should not exceed the maximum PV open circuit voltage of 450V but what if the PV array voltage (VOC or Vmp?) is less than 120V. Does the unit stop charging with solar? Do the PV panels I select, connected in series, need to have their Vmp greater than 120V?
I am planning a battery bank of four 12V 100ah batteries connected in a series parallel configuration. I have seen some videos where the battery bank is attached to bus bars and then to the charger inverter. Is adding a second battery bank (four 12V 100ah batteries connected in a series parallel configuration) to the bus bars the same as connecting the two battery banks in parallel? When adding the battery banks in parallel (no bus bars) I assume the cable size from the battery bank to the charger inverter needs to increase since all the amps are flowing through one set of cables instead of two separate sets when using bus bars.
Thank you for your response.
1) If the solar voltage is less than 120v, the charger controller will not be able to use the voltage. You'll need to wire the panels in series to get a high enough operating voltage to keep the voltage above 120v when in use.
2) You'll want to use a larger enough cable to handle the largest load your inverter will pull. With a 24v system the amps aren't as bad as a 12v system. There are wiring amperage charts online that tell you the size of wire you'll need.
pro tip - never use a metal cart. plastic/resin carts are cheaper, won't ever rust, and avoids any issues with electrical devices
Since you're the Pro, where would I buy a 3 shelf resin cart that can hold 12- LiPO4 batteries, and have the same dimensions of the steel cart? And for cheaper than the $54. I paid for mine at Harbor Freight. It's hen in service for 2 years with no shorts, and no rust yet. I also live in Florida with a high humidity rate and the cart is on the covered back porch. I do have some minimal surface rust starting on the vent covers on the MppSolar LV-6548 charge controllers. I probably should pop them off and shoot some Rustoleum on them this spring
Pro tip put some insulating material between it and the components if you’re worried about it.
@@davebacknolaliki1452PRO TIP: You are right about the insulation.
We're planning on making one of these for our new home.
Do we need solar to charge this, or can we just use the electricity coming in from the power company?
How many batteries can we connect to it so we have longer use?
Also, can we just power our refrigerator, freezer, and lights with this?
Thank you for the video!
You can add as many batteries that you want, just connect them in parallel with your other 24v batteries and you are good. You also can just charge it up from the grid or even from an AC gas generator, no solar needed. The easiest way to power up your appliances would be to wire in a surge protector on the AC inverter with multiple outlets and then just plug them in.
How would this set up compare to a Eco Flow Delta 2 Max? I think it has more storage capacity? Trying to figure out which way to go for a home backup system I would appreciate any help
If I built something like this again, I'd go with a 48v server rack battery. They are just so easy to use. Then I'd chose a 48v all in one charger, inverter. For around $2000 you can get 5120kw of battery and a decent inverter with TONS of solar.
The main benefit of the Delta 2 Max is portability and convenience.
Nice.
Thanks Chris!
Can you add a wind generator with that system
