For what it's worth??? We boondock a lot and until last week I had never used shore power to bring my batteries back up... always with the 10K generator. My 100 amp charger has never put out more than 70amps with my batteries at 50% and then only for 10-15 minutes on a 800AH temp regulated bank. Last week I ran them down to 70% and then charged using the generator 30amps and shore power 42amps which explains why I've never gotten 100 amps. Some type of imbalance with the sine wave from the generator and the charger's restive load.
