I’ve been experimenting with my newish solar battery Represented here is the end of the charge cycle yesterday at about the same time the sun started to set I’ve been powering the freezer with this 2 kWh battery, and every morning there is ~50% charge left, and so far every day I get it up to 90% (by choice) from solar alone I can also do a load of laundry or two, and some vacuuming, without being even connected to the grid (if I get the timing right) Of course this is clear summer weather, so this won’t be the same all year (This is far from sufficient to power the entire house, it’s just an experiment) Essentially, 1-2 kWh that aren’t drawn from the grid on a daily basis #solar

The experiment has been running smoothly so far (TL;DR for today: was a bit uncertain but still managed 1 laundry and some vacuuming, in addition to the freezer) This photo is from today at 1pm, because this morning the battery was much lower than usual, with a cloudy sky a few days in a row I seemed like it was going well so I started a load of laundry, shown in the output in the photo Two hours and a stretch of clear skies later, the battery was upwards of 70% so I got a little greedy and I did some vacuuming too, and it dropped to 40% (no surprise there) I was hoping to get it back above 50% before the sun rays stop shining on the panels, so that it can last the night for the freezer Seems that I am in luck, it’s now 5:30pm and the battery level is at 60%, cloudy skies again but charging a little regardless, and I only need a half charge to tie it up with tomorrow’s first rays (if they are on time) #solar
