[QUOTE="binky, post: 425437, member: 490"] from SMA 3600TL data sheet:-- [B]Protective devices[/B] DC disconnect device Ground fault monitoring / grid monitoring DC reverse polarity protection / AC short-circuit current capability / galvanically isolated [U]All-pole-sensitive residual-current monitoring unit[/U] Protection class (according to IEC 62103) / overvoltage category (according to IEC 60664-1) I checked a few other makes of inverter, and all have some form of DC moitoring, but are a bit vague with regards to residual current. I would assuem they would monitor for DC leakage to prevent destruction of AC components? So I think answer to quesion is you need to check manufacturers instruction for each make of inverter.
