Welcomed the new automatic charge feature in the new FAAB_2525 Firmware.
Feature #17
- Improved SOC control mode:
- - If battery voltage drops below the off-grid cut-off voltage, the inverter will force charge the battery up to （cut-off voltage + 2 V）.
My 12kPV reached the Cut-off Voltage and has been charging for 2 days because the charge rate is ~350W (two 14.3KWh indoor batteries).
I don't see any setting that helps to increase the charge rate above that?
Charge Current Limit: 160
AC Charge Power (kW): 3
Battery Backup Charge Power: 2
On/Off-Grid Cut-off Voltage: 51.2
This system is Grid-Connected with PTO for Back-Feeding to the Grid
I am clearly missing an attribute, would welcome testing any settings to get this to charge faster in that situation.
