My salesman called yesterday and said others have experienced this problem and is sending new DIP switch settings that will lower the inverter current draw which he said would help but would take longer to charge the house batteries. Will post as soon as I'm satisfied.
Strictly speaking, if you've already got 110vAC coming from somewhere (shore power or generator) the inverter shouldn't be drawing anything. The charger should be drawing, and the televisions will be running off the shore power or generator, not the inverter.
When hooking up shore power, or starting the generator, my usual sequence is this:
1 - Turn off all AC appliances that might have been drawing from the inverter.
2 - Turn the inverter/charger to "Off." This is especially important if I'm starting the generator, so that I have maximum available amperage for cranking the generator.
3 - Start the generator or hook up shore power.
4 - Start the air conditioner. Air conditioners have almost double the current draw when they first start up as they do when running, so it's best to start it when nothing else is drawing power.
5 - Once the amperage draw has dropped after starting the AC (usually less than a minute), then I start the water heater and other electric appliances that need to be running.
6 - Then I turn the inverter/charger to "charge only."
Never had a problem with load-shedding since I worked up this routine.
