We have 2 100w 12v solar panels, 3 12v 100ah lifepo4 batteries, a 3000w inverter, 30a charge controller.
We recently finished our solar set up and at first everything seemed fine. We could use a vacuum, and charge a drill, and a couple other things, and not much of the batteries which were fully charged were used. But the second or third time we used the power, just for a little 1500w space heater, the batteries reached 0%.
Now, while it's dark out, as I use the heater, the battery dies down really fast (like from 82-68 in a split second and then 2% every 5sec), but once I turn it back off, the battery goes back up.
But it also only goes back up to 82-86%. Which I think is the max it went to when the sun was out.
So,.. please tell me the batteries aren't ruined.
What changed, why are they dying so fast? How are they supposedly going back up in charge?
