October 13, 2025Oct 13 Around 12:20 I noticed that my PV output was down from almost 5kw to 2.2kw - one of my strings was only producing 300w. Everything else in the house was still working (whole home is on Inverter) - so i ended up restarting both inverters and only after the 3rd restart did the PV string come up normally. I also got these errors from solarmanNormally if i get a HW AV Overcurrent the inverters trip and the whole house goes down but this time nothing happened. I then also saw that F01 DC Inversed failure - which is odd because i haven't touched the PV strings since install. Shut everything down completely and its now working fine. Checking my SolarAssistant data and no values seemed out of range - was this just one of those things? Thinking of checking my PV fuses on both strings - any other checks i can do or do i need to bring in an expert?Edit: We are also having insanely high grid voltage after a stolen cable was repaired - reading between 255 and 268Vac Edited October 13, 2025Oct 13 by mzezman
