I found this inverter in the skip and as I cant get my sma sunny boy working I decided to take it home. After opening it up to make sure it's safe to power up I plugged in the 240ac and 270dc and it started running self diagnostic, after 30 secs it displayed relay-check fail. Would this be as simple as sucking out a relay and replacing it with a new one.
Got some pics if anyone got any idea's
Thanks.
