IMPORTANT SAFETY INSTRUCTIONS
Please keep this manual for future review.
This manual contains all instructions of safety, installation and operation for BSS series Maxi-
mum Power Point Tracking (MPPT) controller („the controller" as referred to in this manual).
General Safety Information
• Read carefully all the instructions and warnings in the manual before installation.
• No user serviceable components inside the controller. DO NOT disassemble or attempt to repair
the controller.
• Mount the controller indoors. Avoid exposure the components and do not allow water to enter
the controller.
• Install the controller in a well ventilated place. The controller's heat sink may become very hot
during operation.
• Suggest installing appropriate external fuses/breakers.
• Make sure to switch off all PV array connections and the battery fuse/breakers before controller
installation and adjustment.
• Power connections must remain tight to avoid excessive heating from loose connection.

GENERAL INFORMATION
OVERVIEW
BSS series controller is based on common negative design and advanced MPPT control algo-
rithm, with LCD displaying running status, this product is artistic, economical and practical.
The MPPT control algorithm can minimize the maximum power point loss rate and loss time,
quickly track the maximum power point of the PV array and obtain the maximum energy
from solar modules under any conditions; and can increase the ratio of energy utilization in
the solar system by 20%-30% compared with a PWM charging method.
Limiting the charging power & current and reducing charging power functions ensure the
system stable with over PV modules in high temperature environment. and increase the pro-
fessional protection chip for the RS485 port, further improving the reliability and meeting
the different application requirements.
BSS series controller owns self-adaptive three-stage charging mode based on digital control
circuit, which can effectively prolong the lifespan of battery and significantly improve
the system performance. It also has comprehensive electronic protection for overcharge,
overdischarge, PV & battery reverse etc, to ensure the solar system more reliable and more
durable. This controller can be widely used for RV, communication base station, household
system, field monitoring and many other areas.
