Only for lithium battery and its BMS is compatible with inverter’s protocol, the parameter “Min
capacity
” need to be set.
Example:
Lithium Battery: usually the lithium will have communication with the inverter, when the BMS is
connected all the charger setting will updated to the default value as below.
Charger Default value
Min Capacity: 10%
Charge cut voltage: 53.5V
Discharge cut voltage: 47V
Charge Max current: 60A
Discharge Max current: 60A
Battery backup discharge Volt: 46V
Lead acid battery: all the data need to be set as the suggestion from the battery Supplier. For
default setting is as below.
Charger Default value
Charge absorb voltage: 56V
Charge float voltage: 54V
Discharge cut voltage: 47V
Charge Max current: 60A
Discharge Max current: 60A
Battery backup discharge Volt: 46V
Note: Installer can set the parameters manually .The parameters
”Battery backup discharge Volt”
needs to be set in the EPS System page.
Based on the different energy platforms between lithium battery and lead acid battery, lead acid
battery need to be set to 3 stages during charging, which is in order to increase its charging
efficiency. In stage 1, it will be charged with constant current till the voltage rises to charge
absorb volt to enter stage 2. In stage 2, it can be charged efficiently with constant voltage, then it
will enter stage 3 for floating.
