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.

LandStar BPL Series Solar Charge Controller

1. Safety Information

 Read all of the instructions in the manual before installation.

 DO NOT disassemble or attempt to repair the controller.

 Install external fuse or breaker as required.

 Do disconnect the solar module and fuse/ breakers near to battery before installing

or moving the controller.

 Power connections must remain tight to avoid excessive heating from a loose

connection.

 Only charge batteries that comply with the parameters of controller.

 Battery connection may be wired to one battery or a bank of batteries.

 Risk of electric shock, the PV and load can produce high voltages when the

controller is working.

2. Overview

 Thank you for selecting the LandStar BPL series solar charge controller. It combines

solar charge controller and LED constant current driver into one unit which is ideal for

solar LED Lighting, especially when dimmer function is needed. The control

parameter can be programmed via Mobile APP, PC Monitor setting software with

RS485 communication interface. The features are listed below:

 12/24VDC automatically identifying system voltage or user-defined working voltage

 3-Stage intelligent PWM charging：Bulk, Boost/Equalize, Float

 Support 4 charging options: Sealed, Gel, Flooded and user

 Battery temperature compensation function

 Digital precision constant current control and the control accuracy are less than 30mA

 Maximum output efficiency of 96.7%

 The output current can be adjusted among the rated power and current range

 Intelligent power mode with 365-day lighting control technology

 Load test function for detecting the system

 Multiple load control modes

 Extensive Electronic protection

 Monitoring and setting parameter via Mobile APP, PC Monitor setting software with

RS485 communication interface

 Use of standard Modbus communication protocol for RS485 bus connections,

communication protocol compatibility much better

 Connecting the IOT(Internet of Things) module and Cloud Server monitoring software

to realize remote monitoring of the multi-machine system

 The RS485 connector can provide power supply

 Aluminum housing for better cooling

 IP67 waterproof degree

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.

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,

when the battery voltage is higher than UWRV, the controller will exit the intelligent

power mode.
