Hi, I hope that someone can assist. I have installed the following: Sunsynk 5KW Inverter, 6x415W panels and 2 x 100AH Hubble Lithium Batteries. When the the sun goes down, and the PV's go to 0W, this triggers an F23 error described below: "F23 AC leakage current or transient over current This is a fault on the main side causing an earth leakage trip, double check all your mains cables coming in do a mega test or installation test on the cables to make sure there is no leakage. This leakage current is from the PV side, 1. Do a mega test or installaEon test on the cables to make sure there is no leakage. 2. Need check PV side ground connecEon". What I then need to do is trip the breaker to the PV and the error clears. In the morning when the sun comes up I manually reset the breaker to the PV and it then works. I've tested the PV's, I also have a earth wire connecting all the PV's together an earthed to the Inverter, but the problem still persists . I've had this error for months. Do I rewire the cable from the Panels to the Inverter? Thank you
