- Today are we discussing the Grape Solar panel array, EG4 10 kW LiFePO4 battery bank and EG4 3000 watt off grid inverter. Links in description below Grape solar panels are 8-100 watt mono panels in series, 5.57 amp output, 23.1 dc volt, 36-cell mono crystalline, 31.89x28.15x1.38 inches. Includes for 12 volt only Grape Solar GS-PWM-10A-IP69 waterproof 10 amp solar charge controller 3-stage charge direct connect mc4 connectors. This would be used to keep AGM/Gel/flooded acid battery charged all the time when not in use. The 10 KWh EG4 LiFePO4 battery bank is 2-5.1 kWh, 100 ah batteries in parallel with an Anderson quick disconnect at end of cable for easy connection to the inverter. The 3000 watt EG4 off grid inverter is able to accept 5000 watts in solar, 500 volt dc input from solar array and can charge 80 amps into battery bank. We already installed the 12,000 btu AUX, 120 volt mini split in the motor home. We will set up and test output from solar panels and inverter to run mini split.

Five years ago, we took an early retirement, sold everything, bought an older MH and hit the road FT. It was the best decision we ever made. We discovered that we enjoy boondocking and it helps stretch our budget too. We quickly learned the advantages of solar and decided to build our solar/battery system in 2 phases, a 12v system for our basic 12v DC needs and a 48v system for our 110v A/C needs. We started with a pair of lead acid golf cart batteries and custom built a 620-watt liftable solar array mounted on the side of our motorhome. We lift the array to the optimal angle to improve their output by 20-30% vs flat mounted panels - even more in the winter, when the sun is lower in the sky. It serves as a nice bedroom window awning too, practically lifting itself to the desired angle with a couple gas struts, and it's easy to clean with a windshield squeegee, standing safely on the ground. This set-up, while far from optimal, allowed us to boondock till we could afford to do better.
We finished the 12v part of our build last January, with the addition of a 560ah LiFePo-4 battery that we built with 8, 280ah "A" grade prismatic cells. We use a Heltec 330amp BMS, and a 5a active balancer to keep the cells synched up. We typically use less than 20% of their capacity daily giving us enough reserve capacity for about a week of bad weather before we have to run our generator for charging. It cost us less than $1,500 to build this 560ah 12v (7.1Kwh) battery, including the high amp BMS and balancer. We chose these cells rather than a pre-built battery because they fit perfectly under the steps of our MH where our old pair of GC-2 golf cart batteries used to reside, saving 35lbs too.
We insulated the battery compartment, cut a 1" hole in our step risers and installed a tiny computer CPU fan to keep this space at close to room temperature, so we don't have to worry about the BMS shutting down charging if they get too cold - or their life reduced from getting too hot. We use an 80A Progressive Dynamics LFP converter/charger, a 1,000w Renogy PSW inverter, an Epever 50a MPPT charge controller and a Lnex battery monitor. This entire 12v system cost us under $3,500 to build and takes care of all of our basic off-grid needs except for air conditioning and microwave use.
By mounting our solar array on the side of our MH, we left the roof free to rack 8, 550W Sungold Power solar panels (4,400 watts) down the length of our 35ft Class A about 15" off our roof, above our AC, fan shrouds, etc. They will cover the entire roof, providing some nice shade with plenty of cooling air underneath, further increasing solar output and reducing the heat load on the air conditioners too. We bought them for not much more than used ones - only 51 cents/watt shipped to our door. We're assembling the components for this build now. We bought our aluminum racking material in Yuma, where we're wintering over this year, for under $400. Our solar panels, wiring, breakers, etc. arrived a few week ago, but we're taking our time to get everything installed over the winter. At 67 yrs old, we're moving much slower these days. Our Sungold Power all-in-one 48V, 5,000W Inverter/100A charge controller/battery charger just arrived last week. Our 48v battery bank will use 16, 320ah grade A prismatic cells which only cost us $1,726 from EEL batteries. So together with our 560ah (7.1 Kwh)12v bank, we will have a total of 23.5 Kwh of batteries onboard - kept charged with over 5,000 watts of solar. We removed our rear 13.5k btu rooftop Dometic AC and filled the hole it left with a powered roof vent. We will be installing an EG4 28.5 seer-2 plug and play 12k btu mini-split heat pump near the roof on the rear which will only draw about 1/3rd the power of our current 14.5k btu rooftop Furrion AC unit. This second phase will provide 24/7 off-grid air conditioning, supplemental heat from the heat pump and allow occasional usage of our front rooftop AC during peak afternoon hours, as well as give us whole house 120v ac power. We'll soon have total off-grid electrical independence on a budget we can afford, reserving our generator for back-up use only.
Very nice set up. Thank you so much for sharing all that with us. Sounds like you have a truly wonderful life in your motor home. You really worked hard and put a lot of thought and planning into your home on wheels. I wish you the best in the new year living your dream. Hope you have a truly wonderful and extremely blessed life.
We will be mounting our array on top of a container and I am trying to figure out the best way to make a pivot point on the rear leg assembly for seasonal tilting - that is a nice little rack system. We will need one to accommodate 38' +/- in length. I would like to be at around 8kw for charging the Absolyte GX 48 volt battery bank. we should be around 7-8kw (average usage) per day for our off grid set up. Great video! Thank you!
I really like the solar array, able to get extra clamps as well. I can get 5-250 watt panels (40 inches wide) or 5-330 watt solar panels on each array ( also 40 inches wide) very easy to assemble array. I might get a few more since they are so easy to put together. Both solar panels I use are around 60 inches long. I also use installed 12-100 watt Grape solar panels on the same array to use on motor home for camping. Can be easy set up at camp site, takes less than 30 minutes to set up and tear down just sitting on ground. With 12 solar panels outed on rack, it Is almost 200 lbs. won’t over with winds. What inverter are you using? Thank you for your input on the video. Hope you have a wonderful and extremely blessed 2024
signature solar also has other ground mounting arrays such as in this linkchiko%20groundflex%20u2v%20solar%20panel%20ground%20mount%20kit%20%7C%20ground%20screws/?ref=oJ3Bgl9hDE3G
@@diy-solar-guy Thank you so very much! 2024 is going to be very, very busy when the snow and weather clear out. Deanna and I are installing an altE Pre-wired Syst, SW4048,CL150, SCP to begin with. We hadn't purchased our batteries beforehand and I wish we had gone the direction of a SW PRO 6848 Schneider (after thought) do to finding a battery bank (Absolyte GX 48v/2,000AH VRLA) that is way larger than we had imagined we would have. Forklift sized (weight wise). I am looking to set up the EG4 Charge Controllers as a primary charging system to the batteries now. A lot more details to figure out before we move to full installation. May just bite the bullet and purchase the XW PRO 6848 and use the SW4048 as a back up in case something should fail down the road. Thank you for taking the time to converse! That hardly happens anymore on here!! Blessings!
@@rongray4118 you are so welcome, I try to respond to everyone with a few hours.
Good seeing you again Pappa do you actually have a video on the mini split install for the RV ?
I have to bring home the motor home from storage. Will be doing an install video. Just to cold right now. Hopefully I will get a warm day to do video. It was pretty easy to install on bumper and inside, a lot easier than I thought.
@@diy-solar-guy oh ok look forward to ur next video 👍
You said "do do". he he he he he
Oh crap, sorry
That;s a Beavis and Butthead reference for anyone who didn't know.@@diy-solar-guy
Sounds to me like you got a bad fuse.
No, not a bad one, just a very poor quality that can not handle 250 amps. Very disappointing in BatteryEvo batteries. Can not recommend. EG4 server rack batteries are less expensive and have much better components inside battery. So far Signature solar has best LiFePO4 batteries that I have found and used. Thanks for your comment and hope you have a truly wonderful and extremely Blessed New Year in 2024.
@@diy-solar-guyYeah, thats what I meant. Low quality.
How much did that cost in total?
Solar panels are $50 each, ground mount solar array was $289, wire is close to $1.00 a foot for black and red. EG4 inverter 3000 watt was $672, EG4 5.1kw LiFePO4 batteries are around $1500 each. Bus bar $35, cable to battery from bus bar around $60 including Anderson 175 amp quick disconnect.
@@diy-solar-guy a battery for $1,500
Wow that's expensive. Is there something more cheap?
@JamesM2000 that is a LiFePO4 battery. I will need 2 of those 100ah, 5120wh batteries in parallel to run my 12,000 btu mini split overnight. AGM batteries will not get you through the night. An AGM battery can only be drained to 12 volts as where a Lithium Iron Phosphate (LiFePO4) can be drained down to 10.5 volts. I have 16-12volt AGM batteries and with all 16 in parallel fully charged I would not get through 1/2 the night before they all reached 12 volts. If you were only looking to run the mini split during the day, you could use the AGM for about 6-8 hours depending on sun angle. I did that at first to cool my downstairs with 2-12,000 btu mini splits during the day and cut my electric bill by 30 percent. I used 8 batteries, 2 sets of 4 in series to make 48 volt battery bank for my 48 volt off grid inverter. AGM and lead acid only will work during the day for solar. Hope this explanation helps.
@@diy-solar-guy thank you for explaining.
I live in Nevada in the desert 🏜 there's too much sunlight here everyday
Usually it's too hot during the day and a little bit cold at night. I was wondering If I could use 5 solar panels of 470watts to turn on an air conditioner during the day with no batteries, Because when the night comes it won't be too hot so I won't need it at night.
@@JamesM2000 you can buy a EG4 mini split that has direct solar input to just run during the day. You can also wire it for grid power to use at night if you wanted to. Also could at inverter and battery bank years down the road if you ever wanted to. Check link in my description of video. Hope that answers your question. Hope you have a blessed day.
