Here is the inside. The two relays on the right are constantly clicking on then off every few seconds. The LED on the little logic board at the top left will go on or off with each toggle as well.

Also, now when the inverter is on it constantly goes into "overload" although when I disable this unit by disconnecting the fuses I am sometimes able to turn the inverter on to get lights and things going.

Any ideas what is happening or how to diagnose further? The big orange cable runs to the batteries and the big black cable to the panels.

Hi all,

I am just getting into this great forum so I am excited to share with all of you and help where I can.

We took ownership of our homestead in March, in the highlands near the North Shore of Lake Superior. It has an existing solar installation that I want to fully understand before making any alterations or updates.

The white charge indicator component is making a clicking sound every few seconds or so, which suggests a relay and I am guessing some sort of error condition. I am an electrical engineer by trade, so I understand the essentials of solar but I am just learning about the various components and their role. The click is especially urgent because my wife and I sleep nearby

Any ideas what this is and how to resolve it?

Cheers!
Patrick
