120A 150A 180A 12V/24V Auto Solar Panel Battery Charge Controller PWM LCD Display Solar Collector
Product Overview
The controller is suitable for off-grid solar system(Independent System), can automatically control the process of charging and
discharge. The battery discharge process is optimized by the controller, which can extend the battery life and improve the system
performance. The comprehensive electronic protection can avoid controller damage in the installation errors and system failures.

Installation Instructions
1. Strongly and securely install the controller;
2. The preparation of the conducting wire:calculate the length of the wire ,and then figure out the installation place,make sure the length of the wire is reasonable to decrease the loss of the electricity;
3. Connect the battery first,pay attention to the anode and the cathode to avoid the inverse connection.the indicator light of the battery will work if the connection is correct,otherwise,it will not ,but the component of the controller will not be damaged;
4. Connect the wire of the solar panel, pay attention to the anode and the cathode to avoid the inverse connection.if the connection is correct,the indicator light of “CHARGE”will be on or flash 10 seconds later after laying outside under the sun,otherwise,please check the connection.make sure the solar energy panel is laid outdoors under the sunshine;
5. Connect the load at the end, pay attention to the anode and the cathode to avoid the inverse connection .if inverse connection ,the led lamp may be damaged;
6. The controller’s maximum wire diameter range: 20-2AWG(0.5mm2-33.6mm2).
