AGM battery tested
4 days of dry camping and never got below 12.5. I don't use the inverter for 110 volts as I don't do TV or movies. ESCAPE! Happy with my choice of 4 Deka 6 volt. 200 watt portable solar and use the genny a couple hours a day. Unfortunately, my camping season is ending for winter. 1st full year of ownership. These are very nice units!
