I have two sv iv 5.6kw conversions in parallel connection. as soon as I fed them with the PV module, the motherboards got damaged and they show error f 09. the pweland company sent me 2 motherboards, I replaced them but I don't dare to connect them again in parallel connection .so far they are working independently each normally. one main and the other spare. EASYN products present serious problems. do not buy.
