AGM Charge Rates and Times
I am interested in knowing how fast AGM deep cycle batteries charge, especially in the upper SOC range. Things to consider: - Ah Capacity of battery/bank - starting SOC or DOD, or Ah's consum...

I have a onboard onan 5500, and a 3000 watt "FREEDOM SW INVERTER/CHARGER". The 3kw I/C charges at (adjustable) up to 150 amps the 2kw at 100 amps. I have the lcd control panel which allows me to program max input from the AC line, so when running off a smaller power source (then 30 amp) it will limit the loads and charger to not trip the braker / overload a small generator. Temperature compensated charging etc.. I usually run the onan until the charger is under ~60 amps, then switch to a 2kw portable inverter/generator, the Costco one. It is quiet, and far cheaper then Blue or Red, and uses less then 1/3 the fuel as the onan for low loads.
