High grid voltage
My inverter has been disconnecting from the grid several times a day. At first I had no idea why. No fault codes logged and the inverter running well within it's limits in terms of PV. After scrolling through my data logger charts I noticed that the grid voltage was steadily climbing up to 253v and then dropping off at exactly the same time the inverter would disconnect. I have since found a settings page on the inverter which has 253v as a high voltage limit.
Obviously I don't want to do anything that would damage my inverter so I am hesitant to increase these values. But I'm thinking surely the settings would be locked to the end user if damage was possible?
Has anyone else had a similar experience?
Should I leave the settings well alone and fit a voltage optimiser? Or is it fine to increase the value by a couple of volts? Or maybe there's something else going on... Is my inverter causing the high voltage? If I do increase it to say 255v will I have the same problem again at 255v?
I have attached some pics for reference
I live in a medium sized town. I'll dig my multimeter out and check those voltages and connections when I get a chance and report back. Thanks
