I am currently experiencing an issue with the CT, which has stopped charging my battery entirely. I’ve been informed that it will take at least a week to have it repaired. In the meantime, I’m trying to determine if there is any temporary configuration that would allow the battery to charge.

When the system is set to Self-Use mode, it only generate enough power(0.400KWh) for household consumption only even it clear sky.

When it is set to Feed-in mode, the PV output reaches maximum(Upto 10KWh), but in both modes, the battery does not charge.

Below are the configurations I have tested and their corresponding results:
Current Battery Capacity: 50%

Case 1

Mode: Self-Use
Min-SOC: 20%
Min-SOC (Grid): 20%
Force Charge: 10:00 – 15:00
Charge from Grid: False

Result:

PV Output: 0 kW
Battery Charging: 0 kW
Household Load: Drawing power from the grid

Case 2

Mode: Feed-in
Min-SOC: 20%
Min-SOC (Grid): 20%
Force Charge: 10:00 – 15:00
Charge from Grid: False

Result:

PV Output: 0.40 kW
Battery Charging: 0.40 kW
Household Load: Drawing power from the grid

Could you please advise if there are any alternative settings or temporary configurations that would allow the battery to charge until the CT is repaired?

The only option I can think that might work is to use EPS mode if fitted as that will use it's internal metering.

Yesterday I turned off the grid power, which switched the inverter to off-grid, and it started to charge from the PV.
