Apparently some generators, the popular Yamaha EF2000iS being one, can under some circumstances produce an MSW signal that can destroy a Progressive Industries EMS unit, and is the reason the company has posted this warranty disclaimer on their website. And BTW, Honda did produce an MSW genset, the EX350 2-stroke. ;)
As for using an inverter, that's exactly what I'd like to do - feed the trailer "whole house" with my PSW inverter by plugging the trailer's main service cable into it's output, the current issue being this isn't advised by Progressive when that main service cable goes on to feed one of their EMS units which in turn feeds the trailer's 120 vac system. Yes, I can physically remove my EMS from the system when using the inverter (or my Honda EU2000i inverter genset) as source power but given a choice I'd rather not if I don't have to. I don't need to "rethink" my electrical setup, I would just like to have clarification from Progressive on exactly what is acceptable, what isn't, and most importantly why not. To date they've not been willing to provide that information. :(
They're easing up on the generator ban I think. Don't know which Honda 2000 they were referring to but they're saying it's "OK" as long as it's ground/neutral bonded. They even sell a plug now to insure that so you don't have to use the EMS bypass switch.
The sharp square surge in a modified sine is what the surge board in the EMS can't handle. Maybe there are too many variables in pure sine inverters for them to KINDA say OK for use with them like they're doing with the generators.
