One consideration when plugging the shore power cord into the inverter is to turn off the 110 breaker for the converter/charger. If this is not done, the converter will attempt to charge the batteries that supply the inverter. This loop will either use excessive energy at a minimum or trip the inverter. We have labeled our 110 breakers for the converter charger and air conditioning and turn them off whenever plugging into the inverter. Works perfectly. Also may wish to avoid using the microwave.
(Highly recommend a pure sine wave inverter when doing this.)
I agree it is a difficult to remember to disconnect the converter when plugging the shore power into the inverter. I think I have a solution. I intend to install a normally closed relay in the power to to the converter (battery charger). I then will wire the relay to open whenever the inverter is turned on.
The downside to this approach is if I forget to turn off the inverter when I unplug the shore power from the inverter then the batteries will not charge when shore power is plugged into land power.
