There's a device in the back EPEVER Tracer series -- looks like the panels wire directly into that. The PV light is not lit. Seems like that might be an issue -- but I'm guessing. There's literally nothing between the panels, wiring, and this EPEVER device, and the wiring is in perfect...

Visual inspection and the wiring appears to be in perfect shape. The only thing it would be would be some kind of animal damage, and there's nothing like that.

Oh now it has a frowny face with an X on the battery icon...

I have an MT50 remote meter (which to be honest, I hate). Starting this morning (I didn't check it over the weekend or yesterday) in full sun, the battery icon in the middle shows empty, the "face" icon shows straight mouth (not a smile) and there are no "charging" indicators. Also the left...

Looking for a way to determine if my battery bank is shot. I had an over-discharge event on my batteries a few weeks ago. Disconnected the inverter, powered everything down except the charge controller, panels, and battery bank. It took a week (middle of winter) but the battery bank did...

I had a trickle charger somewhere but I think I let someone borrow it and didn't get it back. I'll have to buy another one.

The charge controller lights seem to show the batteries on "over discharge."

4 VMAX SLR155 AGM 12V 155ah Deep Cycle SLA Rechargeable Batteries. They worked in the fall. It's like they slowly discharged as the days got shorter, colder, and cloudier. They certainly haven't been able to fully charge in weeks, even with everything disconnected from the inverter. Can I just...

Is my understanding if this device correct? It's just converting the electrical signal for "actual use" and it's safe to turn it off and the battery charge controller will (maybe) continue to allow the batteries to charge, and not overcharge (if they actually charge at all)?

Very, very likely. Which is a little weird because I use the batteries for so few things. But it is certainly winter and colder than it has been, with less sun. But it's like they aren't charging at all. Can I just turn off the inverter so the alarm stops? I know the inverter is used to bring...

Good day all, new to solar -- bought an off grid skoolie here and having my first issues with the solar. Worked great through the fall, now that winter is here I don't know if it's the shorter days or colder temperatures, but the batteries won't charge. Honestly it doesn't even matter, I run an...
