Product overview:
1. Use single-chip microcomputer control which makes the controller has the advantages of intelligent, strong adaptability, reliable function.
2. Use series connection PWM circuit, it is 3%-6% more effective than non-PWM circuit when charging.
3. With LED to show the current battery state, it is easy for the user to know the working condition of the controller.
4. Use industrial grade chip, it can work properly under environment such as cold, high temperature, humid.
5. Use exposed wiring terminal, which makes the wiring more convenient.

Protection
1. Over-load protection
2. Short circuit protection
3. Under-voltage protection
4. Over-charging protection
5. Over-discharging protection
6. Reverse polarity protection .

Installation Instructions
Please first connect the battery, and then connect the solar panel and the load in order.
The controller has reverse polarity protection internally, but if the connection error still may damage your controller.
Please make sure the voltage and current are within the rated range of controller.
