Hi John,
FYI, I have a huge battery capacity (1400AH not counting the starting battery). I also have two 40A chargers and a Honda 2000. When charging from the Honda after my batteries have been drawn a ways, I have to "de-tune" one of them a bit so it's only supplying 20A or 30A. Otherwise, when both chargers are putting out 40A, combined they pull more 110V current than the Honda can supply. Fortunately, it's very rare that I have to resort to the Honda. Usually, either solar or wind provides enough to supply our needs. It's only after it's been cloudy and calm for several days that I have to use it. Running the engine is my last resort as in the tropics, anything is better than running the engine and pumping more heat into the cabin.
