1. Operation instructions:

1). The first step is to connect the battery: If the connection is correct, the controller screen will light up, otherwise, please check whether the connection is correct and stable. 2). These second step is to connect the solar panel: If there is strong enough sunlight (the voltage of the panel is higher than the voltage of the battery), the sun icon on the LCD screen will light up, otherwise, please check whether the connection is correct and stable. 3). The third step is to connect the load: connect the load cable to the load output terminal of the controller, and the current should not exceed the rated current of the controller. 4. The controller will generate heat during operation, and it is recommended to install it in aventilated and heat-dissipating environment.

1. Select cables with sufficient capacity to avoid excessive loss on the line and misjudgment by the controller.

6.A common positive electrode design is applied in the controller. If grounding is required, please ground the positive electrode.

1. It is important to fully charge the battery frequently. The interval should be at least once a month, otherwise, it will suffer permanent damage. The battery can only be fully charged when more energy enters the battery than used by the load. Users should keep this in mind when configuring the system.

2. Please check whether each wiring terminal of the controller is locked, otherwise, the terminal will be vulnerable when the current is excessive.

Hold down the key for 2s to enter the parameter menu.

Short pressto switch the parameter menu (asshown in the figure below); hold down for 2sto enter the parameter setting page (parameter flashes, short pressto adjust the parameter, hold down for 2s to confirm the parameter, and exit the adjustment).

It will automatically exit the setting mode after 5s without button operation and enter the real-time data page. At the same time, after completing the last parameter setting, short press to return to the main page of real-time data.

Note: The setting of boost charging voltage is applicable only in b04 and b07. When the battery voltage rises to thisset voltage, PWM charging will be started. During normal charging, the arrow remains lit, and after entering the float charging, the arrow turns to flash slowly. (It is recommended to keep the default value)

VIII. Controller Reboot and Factory Data Reset

1. Hold down the key for more than 10s until F01 is displayed on the screen to restart the controller;
2. Hold down the key for more than 20 seconds until the screen displays F02 to restore the factory default parameters.

IX. Battery Type Setting

On the main interface of real-time data, hold down the key for 2s to enter the parameter setting menu. Short press to switch to the "Battery Type" setting menu, hold down the key for 2s to enter the setting Interface, and the parameters will flash. Short press to adjust the parameters, hold down the key for 2s or keep 5s without key operation to confirm the parameters and exit the adjustment mode. See "Table E" for controller battery types.

Note: After changing the battery type and system voltage, the controller needsto be powered on again, otherwise it will operate according to the battery type and system voltage before setting.

X. Load-related Parameter Settings

1. Load operating modes

1). Light control mode (00H): The load is turned on or off by the light control signal.
2). Time control mode (01H-23H): The load is turned on by the light control signal and turned off after a delay.
Lc1 means that the load works at night, Lc2 means that the load works during the day, and the light control has priority over the time control to turn off the load. Lc3 means that the load works at night, Lc4 means that the load works during the day, and the time control has priority over the light control to turn off the load. For example: if set to 16h, while the length of night/day is only 12h, then Lc1/2 will only operate for 12h, while Lc3/4 will operate the set value of 16h; the default is Lc1 state.

3). Normal on mode (24h): supply power to the load for 24 hours.

4). C2A mode: the load works for 2 hours a day, stops for 15 minutes, and keeps this mode

circulating.

5). C2d mode: the load works every 2 hours during the daytime, stops for 15 minutes, and keeps this mode circulating.

6). C2d mode: the load works every 2 hours at night, stops for 15 minutes, and keep this mode circulating.

(Note: No matter which load working mode is set, when the battery is discharged to the low voltage disconnect voltage, the controller will forcibly turn off the load. When the controller is active, the load will remain off)

Display	Mode
00H	Light control mode
01H-23H	Time control mode
24H	Normal on mode (factory default)
C2A	The load operates for 2 hours a day and stops for 15 minutes
C2d	The load operates for 2 hours in the daytime and stops for 15 minutes
C2n	The load operates for 2 hours at night and stops for 15 minutes

2. Light control voltage

In the light or time control mode, when the controller detects that the photovoltaic panel (PV panel) voltage is less than this set value, it will turn on the load after a delay, otherwise, it will turn off the load. At night, if the ambient light around the solar panel is too bright which makes the output voltage of the solar panel become high, it will cause the controller to automatically turn off the load. It can be solved by adjusting this value.

Setting Recommendations: It is recommended to keep the default value.

3. Light control delay

When the controller detects that the voltage of the PV panel is lower than the set threshold, it will turn on the load after a delay. This time value can be used to prevent the lightstrom being turned off because of misjudgment caused by car lights or lightning interference at night. Setting Recommendations: It is recommended to keep the default value.

XI. Special Function Settings

1. Short-circuit protection setting: Sc.n means short-circuit protection on; Sc.Fmeans short-circuit protection off, please turn off the short-circuit protection function for equipment with an excessive starting current. The default mode is on.
2. PWM charging setting (only applicable in b04, b07): Pon means PWM charging mode; PoF means disconnected charging mode, it is recommended to use disconnected charging mode for voltage-sensitive loads. The default mode is on.
