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:
- 12/24V automatic recognition.
- 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.
