Solar/Inverter Question
Long time RVer, new solar user. Just bought a new fifth wheel that came with solar. Equipment is: One solar panel that I think is around 170 watts, a Zamp Solar Charge 30 amp Controller, a Xantre...

I don't understand how Wh work with inverters. I changed my Trimetric to read watts instead of amps and the initial draw with the small MW was 700 watts but that rose to 900 watts with the voltage getting lower. The Tri only does AH so I never found out what it all came to in Wh.
The inverter tries to maintain the 120v load, so it draws more DC amps or watts to try to keep up as battery voltage falls. So that skews whatever is going on. I don't think it makes it easier to use Wh instead of AH!
I still have not tried that with a DC load and no inverter in the mix, to see what it says in watts instead of amps as voltage falls. Someday maybe. :)
