Hi Skoolie Fam,
Our power sometimes works and sometimes does not. I'm hoping one of you might be able to point out where common issues are. We are seriously scratching our heads.
We have 2 345 watt solar panels running through a 60A Renogy Charge Controller with a AIMS Lithium Battery (12V 200Ah LiFePO4). We have DC (right now only running lights and fridge). AC – keeping it off while we try to figure this out.
We've tried unhooking the battery and charging that with a special lithium battery charger.
What tends to happen before power turns itself off is a flickering between __% battery and battery overdischarged (flashing 0% on our charge controller).
Recently the issues seem to be happening with the setting of the sun. There didn't seem to be a correlation with this before.
I've also noticed that the charge controller does not come on display panel wise with just the battery—once the solar is plugged in the display then comes on. Shouldn't the battery be enough for this to come on? Charge controller issue?
In the beginning, the charge controller was not set to “lithium” as battery type. We fixed this recently. Could we have messed up the battery or the charge controller?
We have warranties/policies on most things but definitely want things stable before winter.
I've attached the original wiring diagram. We haven't hooked up the alternator (as a backup generator) and aren't using shore power.
Thanks so much for taking the time to read this!
