Hello. I’m new to the forum and I’m hoping it to get some guidance or direction on what to do about the Solar power system and storage that I had installed on my home almost a year ago. I have 42 Canadian Solar Panels with Enphase Micro Inverters, EG4 18 Inverter and three EG4 12kw Batteries. We have not been able to use the batteries at all without significant problems. When using we a getting significant surges in the home that dim all the lights associated with the backed up circuits, so much so that it causes the router in our home to lose power and reset and at times will power down our TV. This continues in cycles of appx 3 minutes repeatedly. There is also an unsettling electrical sound that occurs at the same time. This happens primarily at night, but sometimes during the day as well.
The installer has been out many, many times. They even replaced the inverter under warranty believing that is the problem. However that did not correct the issue. They changed the breaker and upgraded the wiring to the breaker, but no luck. I believe the installer has and is trying to correct the issue, but they have not been able to correct the problem in nearly a year. I honestly believe they do not know what to do to fix this, at this point.
So I have a very expensive system that does not work. The inverter has been throwing a “Bus Voltage High” fault repeatedly. I have since turned off the batteries at the breaker on the inverter to avoid damage to appliances and electronics. Also, for personal safety. This seems unsafe. Sorry for the long post, but I really dont know what to do at this point. Any help is much appreciated.
