So almost 2 years ago, I built a solar power station on a folding aluminum hand truck. With 2-125 AH AGM batteries, 400 watts of rigid solar panels, and a 2,000 watt pure sine wave inverter, the whole business weighs about 250 lbs and provides up to 125 AH (1500 watt-hours) of power which is replenished daily on good days.
I'm now building v2.0, which features a 300 AH LiFePO4 battery, 2,000 watt PSW inverter, and 500 watts of flexible solar panels. It will weigh in under 100 lbs, hand truck included.
I put them both on hand trucks to facilitate moving them around. We don't full-time in the RV, but we do experience power outages at the sticks 'n' bricks. Twice this last week, btw. It sure is nice to be able to still have power where we need it even when the other 471 AEP customers who seem to go out with us go dark.
That 300 AH LiFePO4 battery cost only $1079 (plus, of course, tax). This is about what 100 AH lithium batteries cost just 2 years ago when I built v1.0. So I'm here to tell y'all that not everything is suffering the throes of inflation.
