Hello,
I’m using a blue solar 75/15 controller to charge a single 100ah AGM battery via a 200w solar panel. The load output is connected to a small 12v circuit that powers around 1a of gear (POE camera and a fan)
If I get a few cloud days, the low voltage disconnect will kick in and protect the battery. This is perfect. I can see via home assistant (I have the bluetooth adapter added) that the controller carries on working, slowly charging the battery.
The issue is that when the battery is recovered, the load output won’t reconnect. If I attempt this via the app (on, then off), it won’t turn on either. My only solution is to turn off the solar input via my breaker and remove the negative battery cable. Wait 10 seconds, then reconnect. Everything comes back to life straight away.
Has anyone seen this before?
Thanks!
