SOLAR CHARGE CONTROLLER
USER’S MANUAL
V2.0E
Thank you for choosing this series Solar Charge Controller. Please read this Manual carefully before
using the product.
1. Product Features:
This series controller is a PWM charge controller with built in LCD that adopts the most advanced digital
technique. The multiple load control modes enable it can be widely used on solar home system, traffic signal, solar
street light, etc.
System voltage 12V/24V (12V/24V/36V/48V) automatic recognition;
Intelligent 4 stages PWM charging: Bulk, Absorption, Equalizing, Floating;
LCD display with Back-lighting shows device’s operating data and working condition;
Humanized simple button operation; adjustable charge-discharge control parameters;
Support more kinds of battery: Lead-acid battery (Sealed, Gel, Flooded)
and Lithium battery (LiCoMnNiO2, LiFePO4);
Multiple load control modes: 24Hours Working Control, Light Control, Light and Dual Time Control;
Automatic temperature compensation and accumulated function of charge and discharge KWH;
Double USB output 5V/2A;
Perfect electronic protections.
2. System Connection:
Order of Connection:
① Connected with Battery first, and the fuse should be installed as close to battery as possible, the
suggested distance is about 150mm.
② Secondly, connected with Load;
③ Connected with Solar Panel.
NOTE:
① This series is a positive ground controller. Any positive connection of Solar Panel, Load or Battery can be
earth grounded as required;
② If inverter or other load with big start current is necessary in system, please connect it with Battery, not
solar controller;
③ When disconnecting the system, the order will be reversed.

4. Protections：
Solar Panel Reverse-Polarity
If the solar panel is connected with controller in reversed polarity, controller will not be damaged and will work as
normal when correctly connected.
Battery Reverse-Polarity；
If the battery is connected with controller in reversed polarity (solar controller is not connected with solar panel),
controller will not be damaged and will work as normal when correctly connected.
Battery Reverse-Discharge；
Controller is able to protect battery from reversed discharging to solar panel at night.
Over-Heating Protection；
Once the internal temperature is detected to be higher than a certain value by the controller, it will stop charging
the battery and then recharging the battery automatically after the temperature drop to a certain value.
Battery Over-Current；
Controller will stop charging when excess current is detected from the solar panel, and recharging automatically
after 2 min.
Load Over-Load；
The load will be turned off when the output current of the load exceeds its rated current for a while, and then
turned on automatically after 2 min.
Load Short-Circuit；
Controller will be in protection state when the load is short circuit, and recharging automatically after 2 min.
Battery Low-Voltage；
4
Controller will turn off the load when the battery voltage is lower than the value preset for low-voltage
disconnection, and turn on the load when the battery voltage reaches the value preset for low-voltage
re-connection. The value for low-voltage disconnection and low-voltage re-connection can be set by users in a
certain range.
Battery Over-Voltage；
Controller will turn off the load when the battery voltage is higher than the value preset for over-voltage
protection, and turn on the load when the battery voltage is 1V lower than the value preset for over-voltage
protection.
Lightning Protection；
The lightning protection function of controller is limited and it is recommended to install devices for lightning
protection on the input side to increase system reliability.
5. Troubleshooting：
