Relatively simple scenario: I would like to be able to run the A/C in my RV for about 2 hours when I'm at a rest stop, and then recharge it overnight at my destination. The A/C can run on a TT30 (110V / 30 amp), which works out to about 2.64 kW at 80%. So for 2 hours that draws about 5Kwh. According to GM I should be able to make that work for oh, $725, right? Right?? Apparently not... Instead, it looks to be about a $10'000 setup. For starters, here's a 5kWh battery for $7500: MasterVolt 66025000 MLI Ultra 24/5000 And then, you can't actually use a 3kW inverter, because that seems to give you 1.5kW per leg, so instead you need a 6kW inverter. Which is another couple of grand. Is this really that hard of a project? I though it's something I can throw together for a couple of thousand, but apparently not. I'm even fine with AGM instead of Lithium, but it seems you run into issues when you draw down AGM that fast Aside from literally just ordering a Powerwall, and then unmounting it and throwing it in the back of my truck, is there an easier option? PS: I realize I can run a generator. I would prefer not to.
