SMA4000TL grid voltage too high

[solarfred]

I think I read that this unit can be adjusted in case of high grid volts or fit a G59 relay? Client is getting 257-259v and it is tripping. It is a rural location and rather not get DNO involved if it can be sorted on site. Did I read that right?
Thanks

If you're getting 257-259v consistently then you really need to get the DNO involved. The voltage is too high and it will affecting his leccy bills - and it will also mean his lamps and electronic equipment won't last as long.

Yes OK, but it has on recently become a problem so it may be just a temporary thing but I will advise him to give them a polite call.

Thanks for the info.

Out of interest, are you testing the voltage at the incomer? It will be higher at your inverter, depending on how far from the incomer you are and what size cable you have used.

Not my install but the inverter is right next to the incomer and he would be reading off the inverter display.
