I left every light on and heater going in trailer for about 2.5 hrs with no shore power just batteries. Came out and battery voltage was 11.8 and lights heater still working fine. Turned on shore power and voltage on output of converter was 14.6. Stayed 14.6 for about 15 mins then went down to 13.6. Voltage at battery was 12.2
Kept checking voltages every time converter fan came on and went off. First voltage check output side went back up to 14.6 and battery at 13.1. Fan stayed on for probably 5 mins. When fan turned off Voltage on output side went to 13.54 and battery to 13.12.
Now the voltage on output is holding at 13.54 and battery is holding at 13.12. And that's with lights and heater on. I think it's working good.
Thanks for all the help and I will leave running all night and check in mourning with report.
