question

There is no per tracker limit, by default it will have a global 200A charge limit, so if you aren't seeing PV generation, either your system does not want to charge the battery (I see you have a BMV and a CAN BMS, hopefully the right one is configured as the source in the GX), or your panels aren't optimal.

On a good day you will lose 1/3 of the rated power, more if your panels are less optimally installed, that's before temperature is considered.

Have you checked DVCC and made sure no limits are set there?

You have limited your charge voltage in DVCC, which you should not do.

At 84% your battery is already almost at this voltage so it won't pull more power.

Unfortunately when you adjust settings without understanding the implications, this is what will happen.

Remove the CCL and CVL limit in DVCC, there is no need for that with a managed battery.

That should allow the system to charge properly and ramp PV production.

Salut,

Pune un consumator aditional de 1-2kW, o aeroterma ceva, si vezi daca se mareste productia.

Daca da, si este mai mare de 4kW, atunci e o chestie de consum si MPPT-ul considera ca nu e nevoie de mai mult.

Daca nu, atunci e o limitare din alta parte.

Faptul ca dupa eliminarea unui string productia a fost la fel, si a compensat prin celelalte string-uri, ma duce cu gandul la primul caz.

Trebuie sa iei in consideratie ca MPPT-ul suplineste ceea ce dispare din baterie, deoarece toti sunt conectati pe aceeasi bara de curent continuu de 48V. Si daca bateria, fiind full, suplineste o parte din consum, pana se vede asta si scade tensiunea pe ea, MPPT-ul nu va mari productia sa aduca tensiunea la aceeasi valoare de full. Si bateriile de tip Li au o variatie lenta a tensiunii cu consumul...
