The genset is running (e.g. a convieniently small honda 2000) the microwave and maybe some small lights - then the AC kick in and starts. The start up current is what overloads the little honda - but the onboard inverter (battery powered) in the RV synchs to the honda's unit - et voilá: a small gen can run a relativly big load - or in other words:
The need for drastically oversizing the gen-set just for that fraction of a second when ACs kick in with their big start-up current would be gone / reduced.

best of it:
one would not buy anything new/extra - just some smarter firmware on the inverter (at least if it is a true sine type) would to the trick.

Any electronics gurus tried this before - could not find anything similar so far as a product...

The Yamaha EF3000iSB already uses this technology to provide a 'boost' for motor (air conditioner) starting by utilizing the gen's battery thru the inverter for a boost in starting amperage.

Do any of you guys have an opinion on Onan propane generators? Are they as reliable as the Hondas?
