Solis - Error Over Grid Frequency

    Hi Folks

    Keep getting the following error
    Current Status OV-G-V01 (Error Over Grid Frequency)
    and my Solis hybrid inverter shuts down for 5 mins or so then ramps back up

    Checking Google, it been mentioned that the Grid code/standard may not set properly

    Wondering if anyone knows what It should be set to
    My installer is coming back to finish it off but want to see if I can double check also

    Cheers

    More likely it's the grid frequency that is going too high, and not much that can be done about that.

    Sounds like you're a victim of this problem too - https://www.boards.ie/vbulletin/showthread.php?t=2058171468

    Do you live in a rural area or urban? 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.

    Any neighbours with solar PV?

    I was getting an error like this. It was happening when we connected the RF link to the inverter. It wouldn’t happen when a WiFi link was connected.

    Haven’t managed to work out why it’s happening yet. For the moment don’t have any links connected.

    Oh I read wrong, grid frequency not voltage.

    You were right - I was getting both alarms actually.

    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

    Wow! Glad you got it sorted so quickly, 257 is wildly high!

    260! Yeah that's a tad high, no wonder the inverter shut off.

    Glad you got it sorted,

    What's the normal voltage now, when your not generating solar?

    Was checking the voltage on my mains cable and it doesn't seem to spike past 240ish and all good with the inverter so far :)

    What should the Solis Inverter Standard be set to?

    Mine is G99 but no idea if that is correct?

    Its now showing approx 233
    Have seen it go to 240 but pretty stable now

    ESB said that anything over 253 is a no no - -which I was getting all the time before they fixed it

    I think mine is set to EN50438IE or something like it - -will confirm tomorrow from the inverter (wife in bed, she will get a heart attack if I go in the attic now!!

    Also - -found this
