Hi
Have the same issue
Our system
2 Growatt 5kva inverters
15 solar panels 340w
3 batteries pylontech
2 US3000
1 US2000
The firmware was uploaded to the inverters . Now the maximum solar charging current (pragram 2 on the inverter is at 16 and can't be change) this is to low to charge the batteries full. The maximum charge stop the panel charge and supply at 800w.
If the batteries charge from the grid it go up to 1600w.
Is there a way to increase the maximum charging current?
Thank you
