At the menu interface press “▲”or“▼” could see the parameter, when reaching any parameter that can
be set, press “OK” button to enter the parameter setting state, press “▲” or“▼” could adjust the
value of the parameter. Long press “OK” button for 5s to save the setting data and exit the setting state
or press “

could zero clearing.
3)
Float Voltage：
When the voltage of battery reach to this set point, the controller will start constant voltage charging
mode, limited the rising of battery voltage, decrease the charging current to keep the battery in full condition.
4)
Boost Voltage：
When the battery voltage less than 12.6V, the HVD auto reach to 14.4V at the same time keep 2hours
then back to float voltage.
5)
Dry contact Low Voltage Reconnection(LVR) Voltage
：
When the controller detected and closed the output of
load. If the controller is reconnect the output, the voltage of battery must be higher than LVR voltage or press
“OK”
at main interface force to release.
6)
Dry contact Low Voltage Disconnection(LVD) Voltage：
When the voltage of battery is low, the load output
will be cut off. When the controller detected the battery voltage was less than LVD point, the cut off function will be
immediately working. At the same time, the status of controller is in lock. Users have to charge the battery, when the
battery voltage is higher than LVD voltage or press
“ OK”
at main interface force to release, the dry contact will
resume power supply again.
7)
Dry contact Load mode：
The control default load working 24hours. When the Load Working Time set to 24hours, the
load will keep working 24hours in no fault status. When the load working time set to ≤23H, it means the load start timer
or sensor function. If the battery capacity is enough, the load will be started at sunset. The load will work under timer
setting hours or stop working till sunrise.
8)
Temperature Detection inside controller ：
When the inside temperature of controller more than 75 ℃ , the
charging current will be down, exceed 85℃ closed charging.
9)
Battery Type Selection ：
Program
Built-in 5 types battery data. Different battery will use different parameter.
(Default SEL battery parameter)
Note: for the control parameters related to the battery, we have fully considered the user's actual use.
If you want to modify, please refer to the battery supplier's suggestions, otherwise setting
unreasonable parameters will damage the battery. For lithium battery control parameters, please
adjust according to the battery supplier's recommendations.

Note: when the system is set to lithium battery type, the temperature compensation is zero and the
system will not be able to complete the automatic identification of battery voltage. After setting the type
of lithium battery, the system should be powered off completely and then powered on again to initialize the
