Hello all,
unfortunately I have not found the answer to my question in my search.
I would like to know if the following setup which I bought works:
2 strings with 12* Axitecmodule 405W each.
37,3 Voc, 13,81 Isc
31,4 Vmpp, 12,9 Impp
All this on SmartSolar RS450/100
Batteries Pylontech US3000c
FloatVoltage 51V according to Victron:
Victron & Pylontech UP2500, US2000, US3000, US2000C, US3000C, US5000, US5000B, UP5000, Phantom-S, Force-L1 & L2 [Victron Energy]
Charging voltage according to Pylontech 52,5-53,5V

According to the MPPT Calculator, you can't put the 12 modules in series because the open circuit voltage would be too high:

But now I also want to feed in and thus consumption is always present and open circuit theoretically never present.
If I raise the float voltage slightly and replace the open circuit voltage (which should not exist) with the nominal voltage, it would fit.
Now my question would be, whether this also works in practice?
Or does the MPPT switch me or even perhaps damage?
