    Installing 10kw on a split phase / 2 phase / 480v / single phase, 3 wire (or whatever you want to call it) supply. system is made up of 2 x 5kw arrays with two single phase inverters. Do you meter each inverter separate or can you use one three phase meter and just not use one of the poles?

    Hagar split boards

    In the last 2 weeeks I have fitted 3 5x5 Hagar boards. On testing both pre fitted RCD's failed on all 3 boards. The replacement RCD's worked fine. Be warned. Annoyed over the lost time. First one took a hour and a half round trip to get the replacements.

Everything I read shows the tests being undertaken...
