Yes, I didn't see the connection. The PV is 70kW, the gen is likely in the 50kW range.Well, what kicked off this discussion (300A on the supply side) is hardly a residential PV system.
The biggest inverter gen I've seen is 3kW, The biggest I've heard of is 7kW. **
And I don't know why an inverter gen would be "cleaner" than one with copper, iron, and a rotating magnetic field.
I'm thinking "dirty" involves millisecond to sub-millisecond transients. Slowly changing voltage or frequency swing don't tent to cause any problems. "Slowly changing defined as more than 100milliseconds for a variation not exceeding spec. Which makes me think I need a definition of "dirty". In this context please, I promise I did take a shower this morning.many modern generators are DC generators coupled with an inverter; there's no reason for the power from them to be "dirty".
**Not exactly true. I did see one with a design capability of 40MW for 1/2 hour. But maybe that was a UPS not a generator - it was battery fed. Still, absolutely impressive.
