Equal voltage settings: Press the OK button to enter the menu, press ▲ ▼ to change the
value.
Equal charge
14.8V
Note: 1.The equalisation charging can only be adjusted for batteries with liquid electrolyte,
since high equalising voltages are harmful for sealed batteries. The maximum equalising
voltage value should be stated on the battery manufacturer's data sheet.
2.This window is deactivated if you have selected "Gel" with the menu CONF.
3.Battery charging voltage is passed on directly to the loads by the solar charge controller.
Therefore, during equal charging, high charging voltages can be programmed that may
damage some loads. Please select this equal charge voltage very carefully and compare the
desired value to the battery and load (appliance) manufacturers' data sheets.
Possibilities for programming: 14.0~15.5V/28.0V~31.0V (Default: 14.8V/29.6V).
Note: The fast charge voltage is fixed at 14.0V/28.0V, users do not have their own set.
Day/Night threshold settings: Press the OK button to enter the menu, press ▲ ▼ to change
the value.
D/N threshold
3.0V
The controller recognizes day and night based on the solar array open circuit voltage (only
functional in street-light mode). This day/night threshold can be modified according to local
light conditions and the solar array used.
Possibilities for programming: 3.0~7.5V/6.0V~15.0V(Default: 3.0V/6.0V).
Low voltage disconnect settings: Press the OK button to enter the menu, press ▲ ▼ to
change the value.
Disconnect
Soc = 30%
Note: 1.The difference between disconnect and reconnect threshold must be at least 20%.
If you wish disconnect at higher state of charge you have to first adjust the reconnect
threshold (as per below) to 20 % above the desired disconnect threshold.
2.When you configure voltage regulation, you will find in this window voltage values instead
of SOC values for programming the disconnection voltage level.
The solar charge controller allows the smallest difference between reconnect and disconnect
is 0.8V/1.6V. If you want to program a high level for disconnection you must first increase
the reconnection level.
Possibilities for programming by SOC: 20%~70% (Default: 30%).
Possibilities for programming by voltage regulation:
11.0~12.5V/22.0~25.0V (Default: 11.1V/22.2V).
Low voltage reconnected settings: Press the OK button to enter the menu, press ▲ ▼ to
Reconnect change the value.
Soc = 50%
Possibilities for programming by SOC: 40%~90% (Default: 50%).
Possibilities for programming: by voltage regulation:
11.8V/23.6V~13.3V/26.6V (Default: 12.6V/25.2V).
