If on shore power, Xantrex should switch to grid mode. It will pass thru what it is served up to 30amps from SP unless the charger is programmed to high amperage output.. When on shore power and we want to enjoy high wattage appliances, I turn the charger function down to 10amps from 60amps. This gives the Xantrex a little ďbreathing roomĒ, and relieves it from having to operate at or near max output. Not an expert here, but conscious about over-taxing components.
