Hi,
My system consists of Pylontech US2000B Plus 2.4kWh Li-Ion Battery 8 Modules, Quattro 48V/8000VA/110A-100/100/230V, SmartSolar MPPT Charge Controller 250V/100A-Tr with Pluggable Display, Venus GX and 16x Solar Panels ERA 400W PERC Monocrystalline 24V.
The panels are connected in 4 groups of 4, Then into 2 groups of 8. These groups of 8 are independently switched.
I have a strange situation with charging, I never seem to reach any more than about half of what the panels can produce. So I switched off all the panels until the batteries were at a 30% SOC then waited until the sun was at solar noon. Then I switched on one group of 8 and the charge controller display gave a reading of ~2500w. Switching of this group and then turning on the other group also gave reading of ~2500w. Now this is the strange part, when I have both the groups turned on I still only get ~2500.
Have I missed something in the settings?
Any advice would be gratefully received.
Tony
