Nie, dziękuję Przekieruj mnie tamspeedy9 wrote:@ robak75 You should be interested in WHY your inverter is shutting down first. As you will know, then you can look for a solution to the problem. Instead of implementing random solutions first, hoping that something will help.
Most often this is due to a more prosaic fact than the reactive power settings. The network simply cannot take the excess power. The local consumption is too small and the problem is ready.macif wrote:I have 2 problems with the inverter. One cannot connect to it, and the other that turns off every 20 minutes. I have a message while connecting to the device "unable to connect to the device please try again later." oh yes, for 2 months after the last update. Inverter WiFi is working, cellular data is off. As for switching off, is it possible to limit the reactive power on the inverter? If so, how to do it?
) If your inverter is connected to the Internet, you can probably restore it to the previous version of the system from the cloud. I do not know exactly how it works, because mine was not connected to the net (he did not want to connect to the router either at the request or the threat). The gentlemen ordered me a new dongle, but before installing it, they told me to update the software .. And from January to May 12, they argued on my behalf with huawei support that it could not be fixed.
yes, I know that I have a guarantee, etc, etc .. But what if I lose the real sunshine because of too high voltage in the network ..

After 5 months, huawei agreed with them and sent me a new inverter ..

Can someone add release notes with V100R001C00SPC145 (inverter) and V100R001C00SPC128 (dongle)
interesting that they jumped over 143 and 144.
Regards,
Marcin

But I'm not talking about it, yesterday browsing the inverter options, I found the "voltage increase suppression" parameter, I do not know if it was earlier or only in the 14x updates, but I decided to take a look at it. From what I was able to find out:

I can't find this option in Sun2000 on ios, although I click as it should, I can't switch to expert mode: /

Well, on my part, I can recommend one more simple solution: any large energy receiver (e.g. a heater in a utility water tank), turned on automatically when the set voltage is exceeded. Electricity will not be wasted, and the fan will not turn off.
The easiest way: tuya socket (price from PLN 40-50) + Tasmota software (uploaded to this socket).
TL;DR: A 10-min average grid voltage ≥ 253 V forces the SUN2000 inverter to disconnect [Elektroda, lizak1983, post #19657944] “Huawei is a good inverter, I would not be afraid to install it” [Elektroda, Rhaavir, post #18871886] Latest firmware SPC136 fixes battery and startup issues.
Why it matters: Correct settings stop nuisance shutdowns, improve yield and keep the warranty intact.
