Run AC's from Inverters or not

[CC_Guy]

Chuck,

Your inverters will not perform as inverters when good AC power is supplied from the generator or shore power with 2 exceptions. If the total AC load being drawn through the inverters is high, the inverters will augment the supplied AC source. The other exception is when the source voltage is low. In this case, the inverter will augment incoming shore power to maintain a constant AC output voltage.

Marathon is the king of transfer switches. A typical Marathon will have the following:
-- When you are on inverter power some AC loads will be shed from reaching the inverter through transfer switches.
-- When 240V is not present on shore power, a transfer switch will shed high demand, none essential loads.
-- Only 2 air conditioners can be powered through the inverters. Through a transfer switch you can select which 2 on one of the inverters while the other inverter is dedicated to the one air conditioner, if you have 4 roof airs.
