Then on one service call out to diagnose this strange set of partial blackouts, I heard an internal click while standing next to it, after checking every wire in every panel of this large off grid system. The breaker handles didn’t trip though. A very hard one to figure out.

Ever since then they have had intermittent problems with circuits in their house going dead.<br><br>The array is 14 each Sunpower SPR E20 327 C AC. The array is mounted on a corrugated steel roof on their garage, about 20 feet from the house.<br><br>What happens is that a circuit in their house will either go dead or brown out so lights barely glow. This happens to various circuits and at any time of day or night. The rest of the circuits will work fine and the event will last an hour or two. The breakers don't trip. They have had two different electricians there to check the house wiring and it's all solid.<br><br>Any ideas?
