How close is the transformer that supplies your house? Any other houses on it? You can contact the ESB and see if they will come out and do anything about it for you, but it's unlikely.

Just in case anyone else has this down the line I was getting both alarms quite a lot - and the Solis system would drop for 15 mins or so then revert back up I installed Solis App (you need a dongle on the inverter) so I could see activity on my phone, alerts, alarms, etc. but you can still look at the inverter itself if no app, just easier for me as it was in the attic. Every time system shut down, I would check my power sockets with a voltmeter, to see voltage and it would show a high of approx 261 - -normally 250+. The inverter would show exactly the same in the alerts so pretty accurate I called up the ESB and mentioned that the voltage was high. the response was pretty fast as they take high voltage over 253 as a high priority. They came out within 3 hours, checked the voltage coming into the house, and were showing 257. So they went away and checked the transformer - -all good there and they let me know could be just a bad connection from house to the transformer as they have seen it before. That night, a few cheery pickers were seen and folks checking connections. since then, I have had no issues and system has been running 100% Just wanted to share in case other people have same issue

An old thread but the same problem still persists. Worked fine Jan when installed then from 29th March alarms every day both over voltage and over frequency. Inverter set to UK standard. UK Power Networks have attended and fitting a monitor to the supply. They claim this is a common problem with Solis. I will update with the outcome and any solutions applied.
I have the same issue, it only shows over frequency at startup in the morning . While under warranty solis put on thee irish standard. But the settings were set to the irish values on the non irish en standard. So it made no difference. I don't believe the grid is going over freq. B
The grid have not yet given me their result but they seem absolutely convinced that it will not be them. My installer is ignoring it until I get the grids response meanwhile I am getting multiple error messages every day regarding both over voltage and over frequency. It’s not only a pain but it goes off line every time and so is not generating.
I did have an inverter, that did read 20 odd volts too high, tested with a multimeter. Solis support made a change and a higher "compensation" to be set.
Had to use tape as I ran out of hands to take the photo 😂
