Thank you for your reply. Based on my experience, the 5kW Kodek inverter with a 4kW MPPT will only accept up to 4kW of solar input, even if you install more than 4kW worth of panels. That’s the maximum it can handle. Once your batteries are fully charged, the system will only draw the amount of power it needs from the panels. All the panels will be installed facing the same direction and at the same angle. The reason I want to add that number of panels is to help the system reach its maximum power output earlier in the day, maintain it later into the afternoon, and improve performance on cloudy days

Good day, I would like to find out if it’s possible to use solar panels of different wattages together. Currently, I have 9 x 360W panels connected in a single string. I’m planning to expand my system, but I can no longer find 360W panels. Instead, I’m considering purchasing 9 x 450W panels. My intention is to connect the 9 x 360W panels in one series string and the 9 x 450W panels in another series string, then connect both strings in parallel. Both panel types are rated at 45V. From an electrical perspective, this setup seems feasible based on my understanding of the rules. However, I’m unsure if this configuration will work effectively in a solar application. Could you please advise? Regards

I did manage to get it right. It was firmware problem on my inverter. after I updated U2 to 12.21 it start working and read my commands.

Thank you for documents I check it and the command I send back to the inverter look correct, but the inverter does not accept it or I don't know if he does read it. I die wonder if it cannot be a firmware problem of my inverter display. U2 of my inverter are 12.13. Is there someone hoe done this on and have the same problem and get it fixed. Thanks

Hi I also one of the people trying to communicate with my inverter BMS. I am using Kodek 7.2MAX inverter if I set it up as pylon battery I cannot past the first step. I using ESP32 to send the signal to my inverter the inverter ask for get protocal version ~0002464F0000FD9A I reply to it ~200246000000FDB2 but it seems that the inverter does not pick up that signal. because it keep on asking that but just on different address ~0052464F0000FD95 I don't know why it done that. If I use PBMStool on my PC with the same ESP32 loaded with all the battery info it work that tool think that that are the battery with the correct settings. if some one have did have the same problem and get it fixed can you please help. Thanks Francois
