s Manual For Solar Charge Controller
I.
Functions and Features
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.
