SOFAR 5.5K inverter, GRID OVP alarm

Yesterday I finished the assembly of panels, inverter and security. I have 14 panels with a power of 345W each. At the moment, only the 5x2.5mm2 cable is not just connected to my electrical cabinet.
After completing the assembly, I turned on the inverter. All panels are plugged into one string in series. So far, I have not set anything, and the only thing I noticed is that a few seconds after turning on the inverter, the 01 alarm pops up, ie "GRID OVP".
If the inverter is still not producing power, is it normal or is there something wrong?
On the string I use, I have about 560V.
I'm sorry if the question is trivial, but unfortunately I'm fresh on the topic, and I decided to install a solar farm myself.

This error indicates that the voltage in the power grid is too high, but as I understand it, you have not connected it to the AC yet, if there is no AC, it cannot be such an error, maybe enter the country code and set the clock

Sorry, I wrote at work from memory. These errors are GRID UVP and GridUFP, i.e. too low voltage in the network and too low frequency. So it means that the inverter cannot be used if it is not connected to the grid? I thought that now it would show me the alternating voltage at the output anyway.
I go slowly tapping the settings


I would have a question if I use one string, what kind of input should I choose: parallel or independent? and what is the difference between the two parameters. I would like to test the network, but my friend told me that as long as Enea does not change the meter to two-way, the current meter will probably start to count twice (I have an electronic meter). I am at the moment of filling in papers for a two-way meter and I have left to create a diagram as one of the attachments

independent output, in parallel the input current is divided into two.
When you connect to the switching station, you can easily start it and if the installation works for an hour on a sunny day, you will lose 4 kWh at most, which is PLN 2.40, and if you bake chickens and some soup in the oven during this time, you will probably not lose anything, and dinner will be

Hehe, great, thank you so much for your answer. Tomorrow I will try to connect it and let you know how it went :)

Oh, and does it have to be exactly L1 to L1, L2 to L2, L3 to L3 connection, doesn't the phase sequence matter?

It doesn't have to, as long as you connect all 3

Wind.
Please give me a hint about this. I have had a wonderful micro-installation for 3 days. 5.5kw sofar inverter. What settings should be on the solarman website? Everything on the web? Is it partially online?
greetings

It doesn't matter, I used to record it once and so and so, I didn't notice the difference

I had a peek, on two I have everything and on one partially

I see. I thought it mattered because I set it like this once, then set it differently, and suddenly I got a Grid OVP error and I thought it was because of the settings. Now I don't know what caused this error.

Grid OVP is not from such settings as the country code 12 is Poland, if it still pops up, then measure in the cable connector how high it may be a problem with a weak network from the power industry

For my part, let me just say that I connected everything according to the guidelines (so far to the usual meter and success !!!!!!!!!, at the beginning there was an alarm, but when I changed the type of input to independent, it was all green. I tested it to 0 , 5h and I'm waiting for a bid to connect a bidirectional meter. It's a pity that I did not know to report it earlier, and not only two days ago, but I will wait. It is true that I did not bake the chicken, but the four-pack is Thanks again for your help.

People who try to do the installation on their own, like me, will say that it is not that easy. Not having any construction experience, fitting hooks and sanding roof tiles was the worst. Electrical and grounding connections also took me a lot of time. To sum up, I am satisfied that it turned out cheap and in my opinion it was good (no damaged tiles and all soldered connections), but I would rather not try to do something like this and someone as a layman. I am not surprised that the mark-up is so large (and I was surprised before). There is a high risk that something will fail, such as damage to the roof, leakage, etc. As a professional automation technician, it was not a problem for me to connect the electrical connection, but it also took me a long time to break through with all the wires.
Maybe for those interested, I bought the panels and the inverter at:

the rest, such as hooks, profiles, wires, lightning rod, DC and AC boxes with protections, I bought elsewhere. The whole thing was about PLN 17,000, of which I will recover 5,000 due to micro-installations and over 2,000 from tax returns, it is also profitable, but as I wrote earlier, it is not so easy for a layman
