1. Functions and Features
Solar Lighting Controller is controlled by micro-CPU and has the SOC (state of charge) battery system control function. It can intelligently sense the outside light. It turns on lights at dark,and turns off lights at dawn or the fixed time. This controller also intelligently monitors battery charging and discharging. It will protect batteries by turning off lights
automatically when the battery voltage is low. The controllers will float-charge the batteries by pulse-width-modulation (PWM) automatically as the batteries approach full charge. It will cut off charging current to protect batteries from discharging through the solar panel at dark.
The controller also has a protection circuit to prevent accidental damage.
2. Connection
●The controller must be connected to linear loads such as LED lamps, light bulbs, etc.
●The terminal must be against oxidation and mould, to make sure the connection is in good condition.
●While installing the system, the controller must be connected to the battery before connecting to the loads and solar panel.
●Please reference the below technical parameter to choose the right wire size according to the current.
●Check the negative and positive terminal to make sure you made the right connection.
●Wait 3 minutes after the connection, to make sure the solar controller has finished the program entry before operation.
●If the battery does not fully charge on a sunny day, increase the size of the solar panel or change the battery.
●Please make necessary protection from the water, wet, insect for this solar controller when use it open-air. To make sure the wire connection inside is in good condition.
●Don’t use power from the illumination of light for the solar panel. (The power of the light is too low to charge the battery.)
●Don’t use other DC source instead of the solar panel to charge the battery. It will damage the solar controller.
3. Indicator Light
The controller has a three colors battery power indicator LED light, a green load indicator LED light, and a red charging indicator LED light. The red indicator LED
light (CHARGE) will light when the batteries are being charged through the solar panel. The green LOAD LED will light when the load is turned on. The LOAD indicator also
helps with testing and setup. The three colors battery power indicator light will be red if the battery voltage is low, orange during normal working range and green for a fully
charged battery.

4. Button
The controller has a RESET button, which is used to check and set working parameters:
●Check: Press the RESET button for less than 2 seconds to check it;
●To set working parameters: Press the RESET button for several seconds until the mode of time-setting or light-adjusting appears.
5. Check and Setup
Inquiry: Press the RESET button while observing the LOAD indicator:
●The controller is in light-adjusting condition when the light illuminates fast for 2 seconds.
●The light flashes slowly one time, the controller will turn on the load for 30 minutes, two flashes for 60 minutes and so on up to 20 flashes for a maximum of 10 hours.
Setup: Our controller is in the default light-adjusting mode, no time-setting before sending to you.
Press the RESET button for a few seconds until the LOAD light illuminates. Pressing the RESET button will increase the number of flashes which correspond to 30 minute
increments of the lights being on each night. The light flashes slowly one time, the controller will turn on the load for 30 minutes, two flashes for 60 minutes and so on up to
20 flashes for a maximum of 10 hours.
If you want to change the time-control+ light control into the default light control mode, just disconnect the solar controller, solar panel, and battery,
after a few seconds, the solar controller will recover to the default light control mode automatically.
6. Time-fixed mode
Time-fixed: The time that the light load is switched on can be adjusted between 0.5 and 10 hours. The load will be switched on at dark, and turn off according to the fixed time.

8,Trouble shooting
●Phenomenon:Green light goes out, the red indicator LED light (CHARGE) light.
Reason:Low voltage of battery
Solution:A. Cut off the load, and reconnect the load after the battery recharged.
B. If there is trouble with the battery charging, increase solar panel’s power or change battery.
●Phenomenon :The three colors battery power indicator light is orange and the LOAD LED light is green. But the load stops working.
Reason:Overload or short-circuit happens, the fuse inside disconnected automatically.
Solution: Remove all the reasons which may result in the Overload or short-circuit, 10-20 minutes later, the fuse inside will reconnect automatically, the load will recover to work.
