2 General Information
2.1 Product Overview
Thank you for selecting LandStar series solar system controller that adopts
the most advanced digital technique and operates fully automatically. The
Pulse Width Modulation (PWM) battery charging can greatly increase the
lifetime of battery. It has various unique functions and quite easy to use, such
as:
12/24VDC automatic recognition of system voltage
High efficient Series PWM charging, increase the battery lifetime and
improve the solar system performance
Use MOSFET as electronic switch, without any mechanical switch
Gel, Sealed and Flooded battery type option
Adopt temperature compensation, correct the charging and discharging
parameters automatically and improve the battery lifetime
Electronic protection: Overheating, over charging, over discharging,
overload, and short circuit
Reverse protection: any combination of solar module and battery
The controller is for off-grid solar system, and protects the battery from
being over charged by the solar module and over discharged by the loads.
The charging process has been optimized for long battery life and improved
system performance. The comprehensive self-diagnostics and electronic
protection functions can prevent damage from installation mistakes or
system faults.
Though the controller is easy to operate and use, please take your time to
read this manual and become familiar with it. This will help you make full
use of all the functions and improve your solar PV system.
