LS BPD 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 LS BPD series solar charge controller. The LS-BPD controller
is a waterproof PWM charge controller that adopts the most advanced digital technique.
The multiple load control modes enable it can be widely used on solar home system, field
monitoring, traffic signal, solar street light, solar garden lamp, etc.
It’s an easy operation and cost efficient controller featured as: 
 3-Stage intelligent PWM charging：Bulk, Boost/Equalize, Float
 Support 3 charging options: Sealed, Gel, and Flooded.
 Programmable LVD and main parameters via digital tube and button
 Multiple load control modes
 Extensive Electronic protection
 Battery temperature compensation function.
 IP67 waterproof degree

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
on solid green. Otherwise please refer to chapter 8. Always connect the battery first, in
order to allow the controller to recognize the system voltage.
(3) The battery fuse should be installed as close to battery as possible. The suggested
distance is within 150mm.
