Edward, I just pulled out the lower 110v breaker panel (its still in there behind the door) and just put in another 110v plug but this one is directly hooked up to my inverter/battery system. Less hassle as you would never want the 110v that runs the fridge trying to go from battery 12v to inverter 110v to the heating element, to much voltager drain.

I see the potential for this error to occur: I'm plugged in to shore power and running my battery charger into my aux battery. I flip the switch to the inverter power and forget to turn off the charger. So now I've got a loop with the inverter drawing power from the battery, changing it to 120v AC, the charger is taking that and turning it back into 12v DC and putting it into the same battery. I know this is stupid and a waste of power, but is it dangerous? It seems like I've read warnings about this type of situation or something similar creating some sort of feedback loop or something. The other option is to leave one outlet only and always connected to the shore power, but that is more complicated... Edward |
