pin define is shown above picture
4. Wiring
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 reserved.
2) After power on the controller, check the battery LED indicator on the controller, it will
be green. If it’s not green, please refer to chapter 9.
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.

2) Light ON/OFF(Default)
3) Light ON + Timer
Light ON + Timer1
Light ON + Timer2
Light ON + Timer3
4) Real-time Control
Control the load ON/OFF time through setting real-time clock.
5) Intelligent Power Mode
When the battery voltage is lower than “Under Warning Recover Voltage (UWRV
adjustable)”, the intelligent power mode is enabled; at this time, the LED current
percentage will be automatically reduced in linear with the voltage drop of battery. When
the battery voltage is lower than “Under Warning Recover Voltage (WRW adjustable)”, a
minimum LED current percentage (default 2%, adjustable) will be output. In addition,
Thank you for selecting the LandStar BPL series solar charge
controller. Please read this manual carefully before using the
product and pay attention to the safety information.

when the battery voltage is higher than UWRV, the controller will exit the intelligent
power mode.
NOTE：The load is ON when the controller power on 1seconds. After 1
seconds it will restore to set working mode.
NOTE: In the mode of Light ON/OFF and Light ON/Timer, the Load is
turned on after 1Min. delay.

8. Protection
PV Short Circuit
If the PV array short circuit, the controller will stop charging, clear it to resume normal
operation.
PV Reverse Polarity
Fully protection against PV reverse polarity, correct the wire connection to resume
normal operation.
Battery Reverse Polarity
Fully protection against battery reverse polarity, correct the wire connection to
resume normal operation.
Battery Over Voltage
When the battery voltage reaches to the set point of Over Voltage Disconnect Voltage,
the controller will stop charging the battery to protect the battery from being over
charged to break down.
Battery Over Discharge
When the battery voltage reaches to the set point of Low Voltage Disconnect Voltage,
the controller will stop discharging the battery to protect the battery from being over
discharged to break down.
Battery Overheating
The controller detect the environment temperature through the external temperature
sensor. If the environment temperature exceeds 65 ºC , the controller will
automatically start the overheating protection to stop working, and recover below 50
ºC .
Libattery low temperature★
The controller detect the environment temperature through the external temperature
sensor. If the temperature sensor is less than the low temperature value, the
controller will automatically stop charging or discharge and recover higher than the
low temperature value.
Load Short Circuit
Load will be switched off when load short circuit (≥4 times rated current) happens.
Controller will automatically attempt to reconnect load for 5 times. If short circuit
protection still exist after controller’s 5 times attempts, user have to clear short
circuit ,then restart the controller or wait for one night-day cycle (night time>3 hours).
Controller Overheating
If the temperature of the controller exceeds 85 ºC , the controller will automatically
start the overheating protection, and recover below 75 ºC .
High Voltage Transients
The controller is protected against small high voltage transients. In lightning prone
areas, additional external suppression is recommended.
★Warning: If selecting a lithium battery, it must be set low temperature
value(LTV) according to the charging/ discharging temperature of lithium
battery; otherwise, the lithium battery will be damaged.

④Check the connecting cables and
LED light.
The dimming
function is invalid
The controller does not
match with the LED

product is a step-up
voltage control, If input
voltage is lower than
the rated voltage, it is
not working.
①Replace the LED light
②Reduce system rated voltage
grade and replace the product

For example 24V system change to
12V system, and replace the
corresponding controller
