Value description
The rectifier output voltage in FC state
The rectifier output voltage in BC state
The maximum battery charging current. C
which is generally set to 10% ~ 20% of the capacity of one battery string
When the battery charging current is higher than the 'Over' value, the
controller will generate the battery charge over-current alarm
Select Y to enable this function;
Select N to disable this function
The controller will control the system to enter the BC state when the battery
capacity decreases to the value of 'To Boost Cap', or when the charging current
reaches the 'To Boost Current'. The battery charging voltage is the 'Boost' value
The system in BC state will enter the FC state automatically when the charging
current decreases to the 'Const Boost Current' value and after the 'Const Boost
Time'. The battery charge voltage then will be the Float state
Select Y to enable this function;
Select N to disable this function
The 'Cyc Boost Period' is the interval between the two cyclic BCs. The battery
charging voltage is the 'Boost' value, and the charging time is the 'Cyc Boost
Time'
During the BC state, to ensure the system safety, the controller will forcefully
control the system to enter the FC state, if the BC time reaches the
'BoostLimitTime'
Select Y to enable this function;
Select N to disable this function
The battery charge limit upon DG running
is the battery nominal capacity,
