What do you mean nothing? Here is a package from 4 days ago. The one I posted above.

Apparently, with such traffic, your installation will disappear from his list. A friend used to install me and said that he could do me an installer, but he would lose access.

Gentlemen, I am asking you for help because I am about to cry over this inverter.
I have a problem updating the Inverter.

after getting the package from the support (I posted a few posts above) I entered the inverter as an installer by sun2000, I chose to update the device, manually indicated the zip package on the phone and it also went from the shot.

Hi to all. My plant has panels oriented in two directions, and the shadow appears earlier in one direction. . Is there anyone in this situation who has enabled MPPT multi-peak scanning with good results? Is it worth including? What is the best time frame to scan? Thank you.

Hello Darling.

Due to shadows, shading, etc., there will be power deviations between the different strings, making the output characteristics of each inverter connected to the string complex, showing many peaks. The purpose of multi-peak scanning is to track the maximum power point of each string to improve twine production efficiency. But it will affect the power generated by the modules during scanning (remember to turn off the multi-peak scanning feature if you are not shaded). So you have to understand how long will you be in the morning shade?
If it is blocked for only a few minutes, you can set the interval shorter 5-10MIN, if it is blocked for 2-3 hours, you can set the interval to 30Min.

2 / yes, of course with DTSU666-H

The inverter is no, but some external loger is yes. You can read data via modbus and register.
All in all, the voltages are saved and can be viewed via the Fusion Solar website or application, but only when the inverter is not in standby.

Question about too high voltage in the network above 253V and shutdown of the installation. In the inverter settings there is an option that is turned off "Suppression of voltage increase", if I turn it on, the inverter above the voltage in the 253V network will suppress the production and reduce the voltage?

Here is a good mic for such a situation Link

Has anyone installed this update for the inverter with ending 141, is everything ok and you can go ahead and upgrade?

140 has long been there, from day one without problems, 141 on day one also installed trouble-free operation

Seriously, the guy from Enea's BOK said that? It's illegal as far as I know. And the German standard has the same voltages as PL. Czech has higher.

Check what your reactive power compensation setting is, this feature works wonders. For me, it has reduced the number of exclusions by 3 times.
