Hot auto12/24V 10A LED Digital Display PWM Solar Charge Controller (BUY 15 UNITS GET ONE FREE) (QWP-1410SLC)
* Features of 20A solar charge controller
The solar controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery.
This series solar controller will supply perfect protection functions for the battery; It will make battery work reliability. And the controller could be widely used in the solar system such as lamps, pastoral, frontier and island and so on, it is also could be used for mobile basics, microwave stations and traffic systems.
Theory introduction: Use the industrial MCU as the host controller.
*Installation size & connection:
1. Installation environment: Controller should be installed in a dry and ventilated place.
2. Installation size (kindly find as below) and notice.
3. Connection method (as shown in the figure)
A. Firstly, connect battery correctly (positive on the left). The load of streetlight model will keeps long off not only furing daytime, but also when it under voltage and over voltage. Otherwise, please check all the connection carefully.
B. Secondly, connect solar panels properly (positive on the left), charge indicator LED began to light, into the charging status. Otherwise, please check all the connection carefully.
C. At last, connect load, make sure connection is right (shown in bulb, positive on the left), lamp luminous. The load of streetlight model will keeps long off not only during daytime, but also when it under voltage and over voltage. Otherwise, please check all the connection carefully.
Note: Above connection steps ABC should be connect in order, otherwise, controller will be damaged.
