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 absorp
volt to enter stage 2. In stage 2, it can be charged efficiently with constant voltage till charge
current is more than 1A or time in this stage reaches 2 hours. Then it will enter stage 3 for
oating
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.
Lead acid battery :
all the data need to be set as the suggestion from the battery
Supplier. For default setting is as below.
Note:Installer can set the parameters manually .The parameters”Battery backup
discharge Volt” need to be set in the EPS System page.
