Why don't they include a bus bar when they are selling a 2 pack kit?

28.67 kWh total... close to what an average home uses per day.

"seller pays for return shipping" -- usually a good sign on eBay.

Seems like a great deal....?

And with a Max discharge temperature of 131° F, it means I can keep this in my hot, Arizona garage.

Can someone recommend a decent inverter?
That will at a minimum, power the AC and water heater at the same time.

Also interested in learning what kinds of inverters are best to pair with this/these. Crazy good value it seems, and lifepo4 is super stable compared to the 18650 diy housefires of the past lol

If you're just pairing the inverter to these batteries for high pull loads then the Schneider XW Pro can't be beat at its current $900 price. No MPPT for solar addition but the thing is built like a tank and honestly will last a lifetime.

Srp rates make this hard to justify though. Was considering doing a time of use set up as pure battery backup with no solar, but math makes it hard....even with 30% tax credit it still is over 12 years to break even...

If someone has done a non-solar time of use set up, would love to see the build

Thanks!

Agree, SRP sux. Not sure if anything will ever break even, since my SRP bill is only about $1K/year.

I was hoping to avoid the "demand charge" BS, forgo the 30% fed tax credit, and not even tell SRP about my battery (& possible solar panel) system. It would not be grid tied.
This purchase/setup would be more of a hedge against rising electricity prices & blackouts, brownouts & reliability issues.

Schneider XW Pro is actually on sale for $845. Use code LABORDAY6 here:
