I built my 13kw for $2300. Looked at rack batteries, grade B genfung batteries at 3x the price of mine. My first 24v "tester" pack to make sure the batteries were solid and GTG. This guy on youtube has tested every battery and solar system out there. He said this was the best rack mount.

What type of batteries? I built a 13kw LifePo4 pack with grade A NEW EV packs. Delta on batteries fully charged is .001. I have never seen such a balanced pack before. I run a JK BMS which balances at 2a and keeps the batteries in perfect match...

I run Victron. I think it does what you want. 2 shore powers in. Can run transfer Can pull from battery while charging https://signaturesolar.com/victron-quattro-inverter-48-10000-48v-input-10000w-output-120v-140a-charger-transfer-switch/ How much amps do you need for your battery and what...

Thanks for the 411! I am so glad I didnt bid on the 10k 803. Im scratching my head as to how I can pull 40a. I have a 1 bdrm cabin off grid built around being self sufficient. Maybe I can mine bitcoins with a server array while charging? :)

Ill bribe my neighbor with some fresh butchered red wattle, he has big toys. I only need to move it one time.

The 3000 is rated at 23a at 100% . Im upgrading solar this spring to 48v and doubling battery size and doubling charge rate to 100% gen output, no reserve for other devices to start. Im currently charging at 12a 50%. If my well pump kicks on im at 100%. If then my chest freezer kicks on im at...

OK thanks, thats good info. So, currently Im pulling 12a/120v and that will go to 20-24a/120v when I upgrade. Would the 802a be at 50% with those loads?

What should a ballpark price be for an 802/803 genset? Should I shy away from an 831? Would the 803 be overkill and wasting gas? Occasionally, while charging at 40a/24v and maybe running the 700w microwave on transfer the chest freezer can kick on drawing 23a/110v peak amps and settle at...

Hi and welcome from N Idaho! I watched the OR auction today and wanted to buy 1 of two gensets up for auction. Gen 1 was an 831 air cooled yanmar and gen 2 was an 802a water cooled onan. Gen will be used to charge my homemade Idaho power wall from LifePo4 EV cells. I currently charge at 40a/24...
