Looking for inverter generator to fit my needs

I'm looking for the most efficient and quiet generator available too run an air compressor. It is 230v and runs at 36-32 amp. I presume I need something with at least a 40a circuit, but I would also like a 110v connection to run a light and radio. I think something around 8kw would be sufficient. Does this animal exist? Where could i find it?

I think the largest inverter generators are the Yamaha EF6300iSDE 5500/6300W and the Honda EU7000is 5500/7000W. I believe you can parallel two of the Hondas to get almost double the capacity. Pretty pricey, though! I'd probably go for a single quiet diesel unit instead.

Welcome to the forum. That's an awfully big load! Does it draw 32-36A constantly while running? 36A at 230V is 8300W.

But electric motors will draw a brief spike of current as they start spinning, sometimes double the running current. So the generator might, very-briefly, have to supply much more than 8000W. You could ask Honda or Yamaha what they think, but like tabora said, it sure sounds like you'd need 2 of their large inverter units, in parallel.

What's your budget? You can get a ~12,000W-peak (say more like 9,000W continuous) conventional generator for maybe in the range of $1,000-1,500. But to do that with inverter units will be much more expensive. This package is $9,200, for a pair of Honda 7000W inverter generators, and a parallel kit, for 14,000W peak.
