Auto switch from 120V inverter mode to AC with 240V loads on

I have a question regarding the MultiPlus-II 12|3000|120-50 2x120V. When there is no 240V shore power and the inverter is active there will be 120V from AC-out-1 on both L1 and L2 in the same phase which will power all of the 120V loads. In this state, any 240V loads that are powered across L1 and L2 will be off since the differential voltage in this mode is 0V - makes sense.

When the 240V shore power is restores, and the 240 loads are all still on (Air conditioners & Water Heater), will the initial surge cause any faults or overload the Multiplus 2?

Thank you,

Ralph

Ralph all should be fine if there is a surge then the multis will handle it as long as they are setup correctly
