I'll cut right to the chase: I stupidly (I was in a hurry is my only defense (?)) briefly (10 minutes) reversed polarity on the DC feed on my 15 year old IG 2000. This system was put together by me and has always worked flawlessly. When I discovered my screwup, I of course got the polarity correct, but cannot get it to go back online. NO error codes, just a flashing orange/yellow light from the display, with no response from any panel buttons. I have tried all combinations of everything off, DC off but AC on first, nothing works. I assume they are wrong polarity protected, idiot proof? All I have done is check the ground fault fuse, it's fine. I have missed 3 days of grid tie production, and it's driving me crazy!
This 1.9 KW array is at my crane yard (my day job) and produces enough power to almost zero out my annual power bills. Most of the year the only power used is to open the sectional garage door, the largest load is a 1 KW 120 VAC electric boiler for the radiant floor heat system. With the in slab thermostat set at 50, and the building being well insulated and 40' x 18' it's a good match. I am grandfathered in my utilities net metering system, I get every single watt back, no matter how long it's there, all for 5 buck a month basic connection fee.
