Hello folks, this is a last ditch effort. I thought I would seek your expertise before giving up.. I have been working on this thing for over 2 months and have gotten nowhere. Here is the issue:
Inverter powers on and immediately red GFI light comes on and inverter will not complete the initialization process.
There is no error code on the screen. I have removed most of the Y capacitors and tested to no avail.
All relays are good.
I replaced the current transducer- same problem. Checked most of the transistors and diodes and all appear good. I wish I could get my hands on a schematic which might point me to the GFI circuit.
I just don't know what else to look at here. I have hit a brick wall. Attached is a photo of the board. Anyone have any ideas?
The Inverter is a Power-One Aurora 3.6. I am sure the issue is not with the panels because I did power it up with a 100VDC power supply and had the same issue
