LandStar LPLW Series Solar Charge Controller
---with built-in LED Driver
1. Overview
The LandStar(LS) LPLW series controller combines the solar charge controller and LED
constant current driver into one unit which is ideal for solar LED Lighting, especially for the
application of LED lamp which requires dimmer function. The advanced pulse width
modulation charging methods enables the system charging and discharging management
to obtain the most radical optimization. Make the system reduce the cost, and increase the
system flexibility. The features are listed below:
Apply to lead-acid battery and lithium battery
Lithium battery self-activating function
Lithium battery low-temperature protection function
Intelligent power mode with 365 day lighting control technology
Load reduce power automatically
Load power limitation function
Maximum output efficiency of 96%
Digital precision constant current control and the control accuracy are no less than 30mA
Multiple load control modes
Load test function for detecting the system
Light ON delay time can be adjustable, the minimum value is 10s
Strong penetration and long communication distance with 2.4G communication technology
Low power consumption control function of 2.4G wireless communication
Ultra-low power consumption mode in transporting
Enter the password when it is set parameters
Controller
’s parameter can be set via the APP, RC11 and FC02
Extensive electronic protections

NOTE: Each LED (1W, 3.3V) light is calculated. If the user uses the
unconventional LED-light, the actual input voltage of LED-light must be less than
the max. output voltage.
WARNING
：
BE CAREFUL with electric shock, the output voltage is higher than
the safety voltage of human body.
WARNING: If the LED-light connection number is wrong, it may CAUSE the
damage of the LED-light or the controller.
Connection Order
1) Connect components to the charge controller in the sequence as shown above and pay
much attention to the “+” and “-”. Please don’t insert the fuse or turn on the breaker during
the installation. When disconnecting the system, the order will be reversed.
2) Check the battery LED indicator is ON when you powered on the controller, otherwise
please refer to chapter 8.
3) Connecting a fuse in series through battery positive (+) in the circuit and the battery
circuit fuse must be 1.25 to 2 times to the rated current. The installed distance is within
150mm.
Load self-test function
The load is ON when the controller power on 10 seconds. After 10 seconds it will restore to
set working mode.
