• Discharge capacity control
• RS485 communication interface (optional)
• Discharge Counter of Ampere Hour
• Working Storage Function: record the total run time of system, record timers of error during running time, record times of full charged battery.
• Reliable over voltage protection, short circuit protection, over load protection, overcharge protection, over-discharge protection.
• Accurate temperature compensation, correcting the charging and discharging voltage automatically, improving the battery lifetime. 
• Roundly reverse connected protection.
• Solar Panels, Battery, Solar Charge Controller positive poles are all connected together, adopting negative MOSFET in series control circuit.

The controller could detect the temperature of environment to adjust the voltage of charging, so that the controller should be closed to battery as near as possible.
Recommend system current density of cables less than 3A/mm2 .
Try to use multi strand copper wire in order to connecting with the terminal firmly. Loose power connection and/or corroded wires may result in resistive connections that melt wire insulation, burn surrounding materials or even cause fire.
The battery should be full charged each month. Or the battery will be destroyed.

1.The default night display of controller: When the solar panel input voltage have been detected by controller less than sensor identification point voltage, this graphic symbol will be light.
2.The default daytime display of controller: When the solar panel input voltage have been detected by controller more than sensor identification point voltage, this graphic symbol will be light.
3.The indicator of PV array parameter: When the solar panels data was displaying, this graphic symbol will be light. For example the voltage of solar panel.
4.The indicator of battery parameter: When the battery parameter was displaying, this graphic symbol will be light. For example the voltage of battery, temperature of battery.
5.The indicator of load parameter: When the load parameter was displaying, this graphic symbol will be light.
6.System Voltage: When the LCD shows different system voltage, the controller will adjust the technical data automatically.
7.Numerical Display Area
8.Timer Setting Function
9.Switch Graphic Symbol.
10.Unit Symbol Value
11.Warning: When there is fault, this graphic symbol will be light.
12.The indicator of Load status: Load on,Load off.
13.The indicator of Output power: When the load terminal have output, this graphic symbol will be light.
14.The indicator of capacity of battery: When the battery was in different capacity, the strip-type will show.
15.The indicator of charge status: When the controller is charging, the symbol will be light, float charge will be flash, no charging no display.
