If the continuous amperage output limit is 25 amps for the AC300, in determining how many devices it is limited to, you simply add up their respective Amp consumption.
However, in the case of a refrigerator, for example, which consumes about 5 amps on a continuous basis, but surges up to about 15 amps (or more) when the compressor turns on, do I assume 15 continuous amps or 5 amps for my calculations of how many other devices I can plug into the AC300? For example, if I need to use the 15 amp figure, then I only have 10 amps left for other devices!
I believe the inverter on the AC300 has a surge capacity of 6000 watts, or 50 amps. BUT FOR HOW LONG?
