Hello to the solar power experts on this forum - I am looking for any advice or insights that may lead to correcting an error message on my Sunny Boy solar power inverter. The error code is 3501. This is what I found on the web to explain the code: there may be a ground fault present. The electrical insulation from the PV system to ground is defective or insufficient.
This doesn't mean much to me - I assume it is serious and will require a professional to repair? But hoping there is a slim chance that there is something I can do myself without getting electrocuted?!
If a professional is required, any recommendations are appreciated.
Thank you!
