2. Installation
Install：
2.1 Ready tools and cables. Right cables are recommended. Ensuring
that the current density ＜4mm², which is conductive to reducing the
line voltage drop. Recommended: 20A with 6mm² cable. Check weather
the installation sites compliance with the relevant safety requirements.
Please avoid using or installing the controller in damp, dusty places or
places with flammable, explosive and corrosive gases. .
2.2 Install the controller into a fixed vertical plane. In order to ensure
good ventilation and heat dissipation, please keep the instance over 10cm
around the inverter and also between the backboard of the inverter and the wall.
2.3 To connect the controller and the battery by cables with right
polarity. The battery indicator light on the controller will be on if successfully
connected, otherwise, to check and reconnect
2.4 To connect the solar panel and the controller by cables with right polarity. If there is sunshine, the battery indicator light will be on in a
circular manner to indicate right connection, otherwise, to check and reconnect.
2.5 To connect your load and the cables with right polarity and then connect with the load output port of the controller. Pay special attention to
+ - polarity to avoid reversed connection, otherwise, your load may be damaged.
Demolition: In case of any accident, please disconnect the solar panel, battery and load with controller in order.
Note：Reversed battery polarity will not damage the controller, but you may bear security risks on your load equipments.

2 Description of Button Function:
: Interface loop switch button, use the button to cycle between pages in each switch cycle sequence
shown in (figure 1). Moreover, this button can perform the function of ―add‖in the parameter setting
state.
: This button can on or off load in the main interface. It can perform the function of ―minus‖in the
parameter setting state.
Overall unit state Floating charge voltage Low voltage recovery
Battery types Load mode Low voltage protection

3 Viewing and setting the parameters:
The controller will default entry “battery voltage”interface after correct power-on. This is the main
interface. Use the button could in turn visit the following parameters interface. If the parameters in that
interface could be set, long press the button （＞5seconds，numbers start flashing）to enter the parameter
setting interface; calling off the parameter interface after long press the button again. (The numbers stop
flashing)
3.1 Overall unit state
This interface shows the overall unit state (pictured at right)
It is the default interface after correct power-on, showing charging and discharging
state, 5 bars battery power indication and the voltage of the battery.
3.2 On or off the load
You can use the button on the faceplate to on or
off the load in the default interface.
Note：There is no such function for this button in other interface.

3.3 Viewing and setting the floating voltage.
As pictured at right, the floating charge voltage is showed. When the battery
reaches the floating voltage, the controller will maintain the voltage values by PWM
charging mode to avoid overcharge.
long press the button （＞5seconds，numbers start flashing）to finish
the setting of floating voltage values and use the 、button to adjust the parameter;
calling off the parameter interface after long press the button again.
(The numbers stop flashing) The floating voltage value will be conserved by controller.
3.4 Viewing and setting of recovery after under voltage
As pictured at right, the recovered voltage is showed. After the controller
performs the function of under-voltage protection, the output of the load will be
recovered as soon as the battery voltage recovers to higher than the under-voltage
value.
long press the button （＞5seconds，numbers start flashing）to enter the setting interface of recovery
after under voltage; long press the button again
(The numbers stop flashing) to call off the parameter interface after finish setting.
Setting value will be conserved by controller.

3.5 Viewing and setting of under-voltage protection
As pictured at right, the value for under-voltage protection is showed. The
controller will cut off load circuit when batter voltage is lower than this value,
in order to avoid over discharge of the battery.
long press the button （＞5seconds，numbers start flashing）to enter the setting
interface of under-voltage protection and use the 、button to adjust the
parameter; long press the button again (The numbers stop flashing) to call off
the parameter interface after finish setting. Setting value will be conserved by controller.
3.6 Viewing and setting of load working mode
As shown in the figure at right, the interface of load mode is displayed, and different numbers represent
different load modes.
24h represents Normal Mode; the load is always in power under the fault-free circumstance.
1h～23h represents Light Control with Time Control Mode; at this mode, the controller will start the
load after darkness and will close the load after setting hours.
0h—represents Light Control Mode; Load will be on power after darkness, turn
off the load after drawn.
long press the button （＞5seconds，numbers start flashing）at this interface
to activate the setting interface of load working modes and use the 、button to adjust the

parameter; long press the button again (The numbers stop flashing) to call off
parameter interface after finish setting. Setting value will be conserved by controller.
3.7 Viewing and setting of battery types
As pictured at right, different numbers represent different types of Battery.
b01：Sealed battery (default type for the controller)
b02: Gel battery
B03：Flooded battery
long press the button （＞5seconds，numbers start flashing）at this interface to activate the battery
type and use the 、button to adjust the parameter; long press the button again (The numbers stop
flashing) to call off parameter interface after finish setting. Setting value will be conserved by controller.

4. Common Fault and Handling
4.1Under-voltage protection and treatment:
shows up and flash on the screen means the battery voltage is lower than the under-voltage protection
voltage. The controller has enter the under-voltage protection state and the output has been stopped.
Solution: Using solar panel or battery charger to charge battery, when the battery voltage reaches the
recovery value, the load will be on power again and enter normal working state.
4.2Overload protection and treatment:
shows up and flash on the screen, it means the occurrence of overcurrent or short circuit. The controller
will stop output and enter overload protection state.
Solution: After solving the problem of output short circuit and reducing the load, press the button to
restore power to the load.
4.3Battery overvoltage and handling:
shows up and flash on the screen means the battery input voltage of the controller is higher than rated
input voltage, controller will stop output and enter overvoltage protection state.
Solution: 1. please choose battery with appropriate voltage grade to connect with controller; 2. other charger
for the battery to be removed.
