Bill, Watch out for the 480 delta with the SMA inverter. Even though the product literature says it works, it doesn't. If there's ever a ground fault (PV system or customer facility wiring) on one of the 480 legs, the other two legs will jump to 480V to ground (with much higher spikes along the

Wrenches,             I'm tackling a huge residential system that requires back-feeding the grid at 480 volts, delta (no neutral, right?). We're going to GT 30-50 KW.  The SMA SB3TL-US-10 is one of the few inverters (apparently) that can do this, which I'm planning to use.  The inverter c

Hola amigos y amigas. We're doing our first projects here on the Big Island of Hawaii using 1000-volt rated inverters. The AHJ is informing us that those electricians working on these circuits require training specific to working on 600+ volt circuits. Anyone know of such training(s)?

Hello, Is there any specific conduit you'd recommend for 1000 volt arrays? I can't find any reference of a voltage rating for EMT, ridged, PVC, etc. in the code or spec sheets. Are these types OK to use? I assume its OK as long as 1000v rated wire is used. Am I correct? Thanks. Kirk Herander
