    What standard (country standard) should be set on imported SMA inverter?

    EN50438 or other?

    If there are no settings for Poland, then EN50438

    Undoubtedly, Germany will be better in terms of 253V for those who do not fit.
    However, there are other possibilities: setting ACVtgRPro, preferably LdVtgC.
    The latter seems to be the right way. What do you think?

    The inverter with which I had problems had the Belgian settings - more restrictive than the Polish ones. That's probably why I had problems.

    So far, pure EN50438 and zero disconnections. With this standard, the inverter has set voltage limits: maximum ten-minute average at 253V, and maximum instantaneous disconnection at 260V.

    The maximum instantaneous AC voltage measured on the inverter that I noticed was 251.7V, and a bit later on the meter 250.8V. Sunday afternoon is the highest tension. So I don't have to worry. :)

    What are the upper voltage values according to the standards:
    - Polish
    - German GERMANY VDE 0 126 and VDE-AR-N4105
    - Italian ITALIA (CEI0-21)

    Poland is probably 230V +/- 10%, i.e. 207-253V.

    OK, and Italian and German?

    Partly outdated when it comes to power but voltage OK.

    If the inverter is in Poland, it is to work according to the Polish standard, and not the German or another ... ZE as he says otherwise, i.e. that you introduce interference to the network may cut you off from it.

    What can the power plant do if it sees that the inverter does not turn off at 253 V. And it is on the German code. What are the consequences


    The guest wrote here that the inverter did not turn off and he blew something around 260V - ZE tracked him and sent a letter for a change (it was probably at Sofar) threatening to terminate the prosumer contract.

    And the best thing is that nothing has burned him - which I believe, because nobody produces equipment for "Poland" or "Italy" ....

    With remote, continuous reading of data from a bidirectional meter ZE, such cases can be detected on a regular basis. The question of the right program and the parameters set in it.

    Tia And I want the AI / ML to detect the anomaly :) PGE is unable to issue an invoice for April because "the system is being modernized" ...

    For ET to do something, someone has to notify ET that there is too much voltage. Then they will start looking.

    For example, when a neighbor sees a neighbor boasting about the beauty of production, while your inverter is turned off, you notify the EV about the situation :) )

Topic summary

The discussion centers around the appropriate standards for setting imported SMA inverters, particularly whether to adopt EN50438 or other national standards. Participants suggest using EN50438 if no specific Polish settings exist, while others recommend setting the inverter to German standards for better voltage management. The conversation highlights the importance of adhering to local standards to avoid network interference and potential disconnections. Voltage limits under EN50438 are noted, with maximum thresholds of 253V for average readings and 260V for instantaneous disconnections. Comparisons are made with Polish, German (VDE 0 126, VDE-AR-N4105), and Italian (CEI0-21) standards, emphasizing the need for compliance with local regulations to prevent issues with energy providers.
