T10-G3 - 10 Minute Average Grid Voltage Fault

[czarny]

Dear Fox users.

I've been running a T10-G3 since July and, starting from few weeks, I keep having the usual "10 Minute Average Grid Voltage Fault". Most likely two other houses have just installed PV on their roof and I am getting such error right now.

I read few other posts on this group telling users to navigate through the settings and do some changes, but the guidance already written does not apply to my model.

I can enter settings mode by using password 3210 but inside it I can only navigate to very basic changes and not so accurate like other models.

Living in Poland, my unit is set to adhere to those standards... as soon as it reaches 253V it just stops and wait ....

Is there any action I can do to change those settings in my unit?

Thanks in advance for your help
