Battery upgrade

July 7, 2023

Finally upgraded the house battery from lead acid to Lithium!

The new battery is 12v 150ah by Cloud Energy (http://www.cloudnenergy.com). Approx $450.

The old battery, I'd had for 3½ years; I generated 114kwh with my solar panel(s) to it. But it was not powerful enough to keep my refrigerator going through the night, nor to run my heater more than once in the morning; definitely not both.

I do intend to expand my batter and solar bank over the next several months, taking three or four months between each upgrade. My goal will be 24v 300ah battery bank with 1020w solar generation. Four batteries, four solar panels. But to do that, I will be needing a DC to DC converter, and then an inverter of probably 800w. I do want to have more power coming in than I am using. I need to be able to run my refrigerator on the batteries rather than propane. And I don't currently have enough solar power for that; I used to, but my second 255w panel flew off my roof while I was driving...
