It’s likely going to come down to the AHJ, James, though the City and County of Honolulu electrical department should already have at least some exposure to up to 1,000-volt DC circuits.
One interesting thing I’ve learned is that the standard Hawaii C-13 electrical license may NOT be adequate to pull permits for projects beyond 600 volts. If the four counties hear decide to make life more difficult and play hardball, a C-63 (high voltage) license may be required. And how many companies have that in house? I don’t. For now, regarding our Hilo project, we will need to erect a fence (7’ tall no less!) around the five SMA Tripowers with the required clearance from the front of the inverters. And since the fence would be taller than 6’, it will require a building permit!

We may have a few here on Oahu in development that may go this way as well. Mahalo Nui Loa, James B.

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)? As in where to go to find/get such training?
