We had one of our guys on site checking a 10 or so year old system today (not ours). It is set up as two single phase SMA inverters, on two separate phases of a three phase supply. Both inverters have the following error "VAC BER Disturbance" which is a high grid voltage error.

When testing the grid voltage with the AC isolators turned off, the reading was 220 volts per phase, when turned on, this went to 400v. Obviously the inverters weren't generating. He then disconnected the inverter completely from the isolator, turned it on again and the grid voltage stayed at 220.

We have spoken to SMA about this and they say it can't be the inverters as quote "they don't produce voltage" but we can't see how it can be related to anything other than the inverters given that that the issue only occurs when the inverters are physically connected (even though they are not generating).

Any thoughts?

I am not an electrician, so if I've missed something obvious, don't shout!
