Product Introduction
This kind of controller is design for small off-grid solar generation system, especially for solar streetlight system. Appearance is elegant, operations are easy. It also makes the course which solar panels charge to batteries safely and efficiently.

Basic Functions
1.High efficiency PWM charging mode.
2.Intelligent limiting of batteries max current.
Batteries maximum capacity could be set through this controller. According to the set maximum capacity, controller could calculate the maximum charging current. Then batteries will be protected.
3.DC output has 9 output modes.
4.Over-charge , Over-discharge and Overload protections for battery.
5.Solar charging manual switch.
On the controller you can manually set whether using solar charge to battery.
6.DC output manual switch.
Users could manually set whether use DC output.
7.LCD Display Multi-level Menu; Intelligent Button Settings.

Optional Function
The following functions are available for purchase.
1.RS232 interface
By serial interface communication, you could monitor the whole system, storage and analyze data.
Program could be upgraded by serial interface.
2.Connect PC and controller by serial interface. You could set the parameters on PC and controller simultaneously.
3.Software is free, easy to operate and no need to be installed.
