Yeah, lots more choices out there in the 10+ to 30 kW range….but pretty much all of the larger capacity models only come at 480V.

 

Anyone know why?  We have way more 120/208V applications here in Hawaii than 277/480.

Yes those are interesting. But they are only for 480 Wye, not 240 Delta.....

Is the Fronius 11.4-3 the only 3-phase inverter that can work with 240 3-phase with a hi-leg (stinger)?
