Why 108 Volts for Watts Ratings?
The specs for various brand converters use 108 volts for their input ratings. If a converter is rated as having a max input draw of 15 amps at 108v, for 1620w, what would be its draw using a Honda ...

Got wondering enough that I called Iota to see if I could answers. I supposedly got their tech. guy - trying to get clarification was like trying to pull teeth. Not exactly the kinda guy to chin wag with.
The input current does indeed go down with voltage, not up and their listed 13.4 amps is correct at 108V. He agreed the voltage would normally be at or around 120V and the current would be less. At 120V he said the input wattage would be 935. As far as selecting a generator he said the inrush current shouldn't cause any problems because it's so short a duration and a little Honda generator should be just fine. He also said the 30 amps max. inrush is correct and also depends on the load on the DC side. Just didn't get the answer I was looking for on how to size a gen. I ended up kinda giving up on getting more anwers...
If you have an EMS that cuts out at 102 or 104 volts, what's going to happen to the input current? Would be nice to see a graph.
If it were me, think I'd rather talk tech. with someone like Progressive Dynamics. Or maybe just go buy a 'lil Honda gennie.
