LandStar B series
——Solar Charge Controller
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:
Features：
 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

3 Wiring
Installation Procedure:
Connect the system in the order of ❶battery ❷ load  ❸PV array in
accordance with Figure 2”Connection diagram” and disconnect the system in the reverse
order❸❷❶.
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.
