I have this exact inverter, my version is different (more up to date), the only weird thing I find with it is that for some reason 10 out of my 20 panels are not being considered/connected. I have 9kw in panels and it goes max to 4.5-4.7kw, I assume its a bad connection from the installer but something to keep in mind. (Installer used all PV connections, PV1 and PV2 and im assuming PV2 is wack in the string connection up top or something, if this can only register max 4.5kw-4.7kw of PV then it sucks lol)
