Hi

I have 2 x 5kw inverters running in parallel. Everything was running fine until I added 6 more panels. I will randomly get F23 error one one or the other inverter which then triggers F41 error. F23 according to the manual is something to do with the earthing and F41 is to do with the parallel connection. When removing the new string the problem still occurs although it never was an issue. The installer was there and checked and tested, but can't find any issues with the installation, The errors occur random days and roughly at either 06h00 or 17h00 during the day. Some days it would work error free for 2-5 days and then the errors will occur for 2-3 days back to back...The manual says that if it persists Deye must be contacted, but I sent them a mail and no response

Any thoughts?

Check this thread > https://powerforum.co.za/topic/19279-deye-8kva-f23-fault/

Specifically the post by @TaliaB about earthing. Are the new panels earthed correctly?

Its A Grounded DC Cable And A Thorough Check Of Your System Should Reveal, A Braized Cable, MC4 in water or i contact with moisture quire a few points to check

Was out of the country for a while. Will give the advice through to the installer when he comes on Monday. I picked up a few other small issues, but was rectified by a software update from DEYE...(time not holding/screen randomly scrolling or changing and coming on out of it's own)
