    Thank you very much for sharing your experiences with me and I am asking for more, for which I thank you in advance. Are there two wires coming out of the bidirectional meter, separately for a home installation and a separate one for photovoltaics. Is it one 5-core cable to which you can connect, in front of the home fuse box, a photovoltaic cable secured with a suitable switch. Can you look at your network on the Internet as tz. guest. Just like on the link solaredg gave me. I can choose any country there, any user, I just haven't checked if you are there as krissgut or as a different user. Can you write to me in which region of Poland you have your installation. I am from Olsztyn. On the Internet, the power of the viewed installation is given, but there is no place and therefore I cannot define how it relates to Olsztyn. I look out the window, the sun is full for me, and the guy is barely 50 W on an instance of 5 KWp.

    From the meter 5 wires, but you do not connect the inverter directly to the meter, only to the main security in the box at home - at least I have it. So if there is no electricity in at least one phase, the 3-phase inverter does not work, but if you cut off the power from the grid and supply electricity from a small generator, for example, on a beautiful day, despite the lack of electricity from the grid, you have your own electricity.
    I am from the vicinity of Krakow, so a bit on the other side of Poland. Today my bad weather was only 14 kWh, but yesterday it was 51 kWh.
    As for the preview, as a guest, you are looking by name or ID?
    I see that you have concerns about buying - I had too, but now I'm happy. The rule is that if you have several roof slopes or shades, run Solaredge, if you have one slope, run anything else, because it's a pity to overpay for optimizers.

    You can connect the inverter to any switchgear if the power cables of these switchgears meet the requirements in terms of expected current and voltage drop.

    As for two different slopes without the expected shading, it is used with, for example, two MPP inputs, it will meet the same and economically more advantageously

    Here it is described what the owner of the installation can have access to and how the installer allows him.

Topic summary

Czesław seeks advice on optimizing a photovoltaic (PV) system with 18 panels on one slope and 5 on another, both on a sloping roof covered with ceramic tiles. The discussion highlights the need for an inverter capable of handling the power output from both slopes, with suggestions for inverters with multiple Maximum Power Point Tracking (MPPT) inputs. Recommendations include using a SolarEdge SE5K inverter with optimizers to manage the differing panel configurations effectively. Concerns about voltage limits and the potential for power imbalance are addressed, with advice on ensuring the inverter's specifications align with the panel outputs. The conversation also touches on the importance of monitoring individual panel performance and the implications of using optimizers for efficiency.
