Ok I need help.
I have a 2015 42' toyhauler. With a onan 5500 Gen. It has 2 6volt interstate AGM battery I think something like 400+ amp hours combined. I also have a solar setup on the roof 400 watt system. And a WFCO 100 amp smart converter charger. Before the last trip I took the converter charger out and tested it. It is working and does put out more when load is on the system or when the battery is low.
Ok here is the problem I am having. Battery drain is not making sense at all. and has begun becoming a problem over the last few trips. Example I went on a 2 day trip this last weekend. I had the battery's taken to Interstate, to be tested and topped off before the trip and the battery's tested perfect and topped off great. Put them in the trailer. It was super cloudy on this trip so the solar was only putting about 2-3 amps out an hour on the trip. I have been a battery **** from the time this problem reared its head. Almost no lights on in the trailer for 95% of the trip nothing used during the night other then the propane heater and fridge. It was cool outside but the heater did not run all that much maybe kicked on 5-6 times total during the night. Woke up the next day and battery's were drained down to 11.5 volts. Was able to get the gen running and it ran ALL DAY from 6am until 7pm The battery's never got back to full around 3/4 full or about 12.3 volts. One of the weird things is even with the Gen running it still shows the battery's are low. The only time I ever see good voltage on the battery's is when it is sunny out and the solar is showing 14 volts and putting in 8-10 volts into the battery bank. When its sunny out with the solar working it I can tell at that time we are running on full solar.
I just don't know what to check at this point. I don't know why the Gen running all day wont bring them back up. And I have no idea how with every single light out on the trailer all day and over night. How just running the heater and fridge can drain 2 6 volts over night. Its starting to get frustrating. Any advise would be greatly appreciated
