I've been using this system for about a year with no issues. This morning I woke up with no power. I have 48v trophy batteries that aren't dead but for some reason the inverter shut down. I tried to power it up several times with no success but after about 90 minutes it is working now but now won't except power from my generator. The indicator light comes on but the line showing its charging the batteries isn't showing and I have verified with meter it's not charging. Any ideas? It is charging via solar panels.
