Xantrex inveter 1800 with solar

[techsol]

I have a Xantrex 1800 watt hf power inverter in my RV. I have 400 watts of solar coming in and an mppt epever tracer charge controller.. When I'm on shore power, which is not very often, the inverter will show, 3 stages of charge, bulk, absorb, full. On a good solar day I bring in about 22amps per hour, which fills my batteries in no time at all, but the inverter never shows the same 3 states of charge. It fluctuates thought the day, get as high as 14.5v but always by the end of the day the usual 13.3 and by morning 13.0v or 12.9v. Now I'm not complaining as these are good numbers and my batteries are always full, but why 3 states of charge on shore power only? Thx

Real simple, you may think your batteries are getting fully charged on solar, but they are not. There is not enough sun hours in a day to complete a 3-stage charge. Where as commercial power can do it every time because power is available 24 x 7. It takes up to 12 to 16 hours to get all the way through to the third stage.

thanks, makes sense.

Along with not having enough sunlight hours to perform a 3 stage charge, the Xantrex charger is much smarter then the epever tracer charger
