When Batteries are connected to a 50kW Inverter, at first switch on the HV Batteries undertake a Force Charge from Grid to 100% so that the BMU can calibrate each individual Battery Unit. This is normal and may take up to 24 hours.
The Battery System will not obey System Mode Timer until this Charge and calibration cycle has completed.
Please Note, if there is sufficient PV then a combination of PV and Grid will be used to charge the Batteries to 100%.
