Product Description

60A 12V/24V/36V/48V Auto High Power Solar Charge Controller(QWSR-LG4860)

This controller is designed for DC power supply system, small and medium-sized pv modules power system, using a dedicated computer chip to realize the intelligent control, all chips adopt industrial level, can be used in harsh environment.
Meanwhile system offers specific indication for the charge, load , sorts of failure and various protections such as short circuit, over-load, over charge, particular anti-reversed polarity protection and so on, the controller used computer chip to sample the parameter of the battery voltage, photovoltaic cell voltage, discharge current and environment temperature. According to the battery's character, realized the accurate control to discharge rate, correction of the temperature compensation through special control model
calculation.charging with the intelligent PWM dim way and charging compensation in accordance
with the current temperature of the battery, compensation factor is 3mv/ºC/unit.LCM could show
all of the parameters and modes. Dial switch need to adjust if adopting different voltage system.

60A 12V/24V/36V/48V Auto High Power Solar Charge Controller (QWSR-LG4860)
Main Features:

1.Common cathode design adopted.

2.LCD screen for displaying system working status and parameters.

3.Adjustable charge and discharge controlling parameter.

4.Boost Charge mode auto shifts on when the battery voltage is lower than boost charge return voltage.

5.Double temperature sensors design, inner sensor for inside temperature detection, and the outer independent sensor for detecting battery temperature which makes the battery temperature compensation more precise.

6.The controller can work out daily battery charging and discharging capacity which makes it more convenient to evaluate controllers and the whole system.

7.It possesses overcurrent protection when charging which can decrease the charging current so as to protect the charge circuit if it exceeds the rated current.

8.It will proceed equalizing charge every 30 days to protect the battery from vulcanizing.

9.Industrial grade chips and precision components adopted which can work under cold, hot and moist conditions.

10.Double MOS in series circuit adopted in charge circuit, PWM charging control to improve charge efficiency.

11.Power-fail protection for saving tech data which makes the system operation more reliable.

12.3 different load working modes: Pure light control, Lighting + Timing control, load open all time.

Installation and connection instruction

1 ,Installation of controller must be reliable,size is as follows :
Boundary dimension:140×90×25(mm)
Installation dimension:133.5×69.5(mm)

2 ,Preparation of the wire:
Adopt the wire matching the current,plan the length of wire, strip 5mm insulation of
one side of the controller's terminal and try to decrease the length of the connected wire so that
a reduction in electrical loss.

3 ,Battery connection
Pay attention to the pole + , - , do not connect reversely. If connect correctly, the
controller will start to work or it's necessary to check the wire connection and battery's situation.
Users could connect the system followed by the order showed in the below figure.

4 ,Photovoltaic module connection
Pay attention to the pole + , - ,if sun light is tested, photovoltaic indicator will light on or
it's necessary to check the connection.

5 ,Load connection
Connect the load wire with the controller's output terminal, the current can't surpass
the controller's rated current and pay attention to the + , - pole, for avoiding damage to the
device ,do not connect reversely

6 ,Temperature sensor connection
Connect one side of the temperature sensor to controller, the other side to the battery.
There must be a good thermal contact with the battery shell.


System protection function description

1 ,Overtemperature protection
Controller temperature exceed 90ºC will close the load and charging efficiency will decrease.
Temperature less than 85ºC will recover.
Battery temperature exceed 55ºC will close the load and charging will closed. Temperature
less than 55ºC will recover.
2 ,Charging protection
Decrease the charging efficiency when PV array charging current more than  Rate charging
current and less then 1.25 times of  Rate charging current for 60s.
Decrease the charging efficiency when PV array charging current more than 1.25 and less then
1.5 times of  Rate charging current for 5s.
Decrease the charging efficiency when PV array charging current more than 1.5 times of  Rate
charging current for 1s.
Recover after decrease charging efficiency for 1min.
3 ,Over discharge protection
The controller will start the over discharge protection and close the load when the battery
voltage is less than over discharge voltage and duration 5s.
The controller will start the over discharge recovery protection when the battery voltage
exceed the over discharge recovery voltage.The next night will remove automatically.

4 ,Short circuit protection
Short circuit:
The first time short circuit in one day will recover after 5s later.
The second time will recover after 10s later.
The third time will recover after 15s later.
The forth time will recover after 20s later.
The fifth time or more than five times will recover after 4hours later.
Also can recover by long press the key!

5 ,Over load protection
Over-load protection:
Close the load when load current more than  Rate load current also less than 1.25 times of  Rate
load current for 60 seconds;
Close the load when load current more than 1.25 also less than 1.5 times of  Rate load current
for30 seconds;
Close the load when load current more than 1.5 also less than 3 times of  Rate load current for 5
Recovery normal after overload stop 60s later, not have the limited times.

6 ,Reverse connection protection
This controller including the PV array, battery and load reverse connection protection.

Warning : This controller is a high power device, please read the instruction before use,
take extra care when operating.

Safety notes:
1. read the instruction and attention carefully before use
2. Do not disassembly and repair the controller freely
3. Avoid direct sunlight and pay attention to ventilation When installation
4. Install appropriate fuse or circuit breaker on the outside of the controller
5. Disconnect the external fuse or circuit breaker when wiring
6. Be careful to prevent short-circuit when installing the battery
7. To ensure adopt the correct wire diameter, connect firmly, fasten the wire after connection
8. Temperature resistance should be fixed on the battery,the othe end connect to the controller
