You will need a 'transfer switch' to prevent "shore power" Inverter output from reaching 120-VAC appliances at the same time -
unless you are are speaking of a very expensive all-in-one Victron Multiplus II unit, an Inverter converts 12V into a 120-VAC while generating its own 60-cycle frequency.
A simple inverter must never have live "shore power" connected to it's 120V output ports, because the 60-cycle shore power frequency is not "in phase" with the 60-cycle frequency being generated by the Inverter. The Inverter will be destroyed, and other 120-VAC equipment (air conditioner power converter, etc) wi8ll probably be destroyed at the same time. The problem could continue back through the RV park pole and damage equipment in other sites.

A transfer switch assures that only one of two feeding pairs of "hot" + "neitral return" wires is active into the TM's 120-VAC circuit breaker set at a time. If you are not installing a Multiplus, you will need one of those.
