Functions and Features
I.
1. Series PWM charging control makes sure the controllers staying cool when
charging stopped.
2. The controller use a MCU as the controlling core, so charging control process is
more intelligent, and charge control voltage more accurate.
3. 3-stage charging control( Bulk, Absorption, Float), to full-charged battery faster.
4. 4-stage LED indicator which shows the battery's SOC and charging stage.
5. 2 kinds of settable load working mode: Normal and Automatic light mode. the
controller will power on the load after darkness and will power off the load after
sunrise.
6. 2pcs of 5V USB power output ports.
7. 1 buttons to control the load switching and load mode switching.
8. The controller uses low conduction resistance of MOSFET as the charge and
discharge control device, utilization of solar panel would be more higher, charging
and discharging loss would be more less.
9.
All sorts of perfect protect function: reverse-connect protection for battery,
reverse-connect protection for solar panel, prevent backflow function, low-voltage
protect, over-voltage protect, over-load protect.

- Page 3 Load Mode Indicator Normal Auto Meaning The LED indicator is on, load control is in normal ● mode, load is in normal power supply condition. Flashing fastly, load control is in normal mode. Load over current has occurred.the load have been powered off automatically.
- Page 4 4.Short Press The Button Turn on or turn off the load and unlock the protection of controller on any of the two Load modes (Battery over-voltage protection could not been unlock). 5.Long Press The Button After 5s, load control mode will switch between the two modes. Corresponding mode indicator will be on.
- Page 5 In the guarantee period: ● Do not operate according to the user's manual. ● Use the controller under the condition which is beyond the using standard and technical requirements. ● Repair by yourself or reform by yourself. ● The inappropriate environmental condition which can cause the breakdown and aging of the apparatus.
