This weekend, a major storm blew through Michigan and knocked out power to almost 200k people. We're still out as I type this.. What a joyous occasion! I got to activate my off-grid system in a real world test for the very first time..... and discovered a strange glitch I can't seem to figure out.
Every few hours, the Sunny Island SI6048 inverter will trip out and stop making power for about 3 seconds.. then reactivate again on their own. A review of the event codes shows the Master is throwing error code (W331 Grid/generator disconnected due to anti-islanding).
My system isn't connected to any grid or generator, it is a stand alone grid. All it does is take battery power, convert into 120/240 split phase, and send it into the breaker panel through a double pole breaker on an interlock. The main breaker in the house's circuit breaker panel (150 amp) is off to isolate the house from the grid. There is no generator connected, no other inverters except the Slave unit. The only other source of power generation that is currently connected is the AC Coupled solar array which uses two Sunny Boy inverters.. and since its after midnight and very dark outside, I seriously doubt the panels are generating any energy.
Anyone have any clue?
