Generator kicked on
Wed night about 11:30, my backup propane generator kicked on. I went out to the solar shed and the SOC was 81%. The generator is programmed to come on when the batteries get down to 50%. After a half hour or so it turned off. I checked the batteries and they were now 80%, so it wasn't charging the system. The next day while flipping through my read outs, it said "last generator use - April 23". That's the day they tested it. Why did it come on? It has been getting down to 19-20 degrees at night. Does it come on occasionally to charge the generator battery?
