Everything has been checked by the installer and everything is withing spec. I am still getting the error sunsynk F17:z_PV_OverCurr_Fault and it was 4 times today already during loadshedding and the sun is out for the solar panels. I have also started to get this error now every so often : sunsynk F18:z-HW_Ac_OverCurr_Fault and everything is correct or withing specs. It has been queried with support numerous times and the latest firmware has been done as well.
