Check your cables
Customer's Solar Energy system.
Not a Mi-Grid! Not our design. We helped out a local customer with an older competitive system from an out of business company. It is a Sunny Island system (2011) about equal to a Mi-Grid 2000, but no generator and the battery bank uses cheaper AGM batteries. The homeowner had the batteries replaced about a year ago. This past week was one of the first times they needed the backup power - And it did not perform! Look at one of the problems!
Lots of other issues as well, mostly wrong breakers and undersized wiring! And there were NO WIRING DIAGRAMS or instruction manuals!
If your battery cables are loose and melting the battery terminals, you have a problem! Yes, that is melted lead on both sides of the terminal...
