Folks stating they can't recharge over 90% or that it takes forever on generator to achieve a full charge must have something wrong with their charging system.
Granted the common "converter" installed by Elkhart doesn't do a very good job, but they're not the only charging option available.
My Magnum charger will keep pushing high amps right to a 99% state of charge... With a 2000 watt generator it takes about 4.5 hours to recharge my 800ah bank from 50%.
I'll go about two days on battery, then run the generator a little while and fill em up again. Two gas cans last a long time, I'm not constantly running to the gas station for more petrol.
I could spend 5 or 6 grand on solar, maybe I'll get a full charge in a day, maybe not. I'll still need the generator for the maybe not days. In that case, why carry the solar. Maybe my logic is flawed here.
