I do not know, but it has been a recurring problem recently.
- August 6, 3am, out for 1.5 hours
- August 11, 3:30am, out for 1.5 hours
- August 11, 1:30pm, out for .5 hours
- August 11, 5pm, out for .5 hours
The first one there was a loud enough bang to wake us up immediately before the power went out. The outages seem to cover a similar area, so I would not be surprised if it is the same piece of equipment that is failing.
My 17 panels are showing 5.6MWh lifetime, which is just since February. Our most recent bill I paid $20 for electricity, but we also had a dehumidifier running 24/7 for a week.
You know how some things have a negative value, because you have to pay someone to take them away?
