※Thank you for selecting the LandStar B series solar charge controller.
Please read this manual carefully before using the product and pay attention
to the safety information.
LandStar B series
1 Overview
LandStar B series is a PWM common positive solar charge controller that adopts the most
advanced digital technique. The multiple load control modes enable it can be widely used
on solar home system, traffic signal, solar street light, solar garden lamp, etc. The features
are listed below:
Adopt high quality components of ST,IR and Infineon, make sure product lifespan
Terminals have UL and VDE certification, the product is more safer and more reliable
100% input and output in the environment temperature range
3-Stage intelligent PWM charging：Bulk, Boost/Equalize, Float
Support 3 charging options: Sealed, Gel, Flooded and User
RS485 communication interface and Modbus communication protocol
Battery temperature compensation function
Energy statistics function
Multiple load control modes
Extensive Electronic protection

NOTE: The LS-B series is a positive ground controller. Any positive
connection of solar, load or battery can be earth grounded as required.
NOTE:While wiring the controller do not close the circuit breaker or fuse
and make sure that the leads of "+" and "-" poles are connected correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of the
controller must be installed on the battery side with a distance from the
battery not greater than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the inverter
directly to the battery, not to the load side of the controller.
