(with Optional MT50 LCD Remote Meter)

LandStar Series is a new generation solar controllers, especially designed for small independent solar power generation system, mainly applied for the loads that need long-term power supply, light control, time control, or automatic control switch system that light control and time control combine. Such as: Household(Home Use) Power Supply System, Automatic Test Equipment of the Field, Solar Street Light, and Garden Light System, etc. The controllers adopt the most advanced digital technology design, full-automatic operation, the battery charging method of its  pulse width modulation (PWM) can greatly increase the battery lifetime.

Main Technical Highlights

1. 12/24V Voltage Automatic Recognition or customize the Controller’s Working Voltage;

2. High-efficiency Series PWM Charging Method extends the battery lifetime and improves system performance;

3. Use Power MOSFET as the electronic switch, no any mechanic switch;

4. Multiple load control methods and intelligent memory functions increase the flexibility of the loads output;

5. Four types of Battery Charging Procedure of Sealed, Colloids, Open and User-defined can make any choice;

6. With temperature compensated charging control algorithm, the system can automatically adjust the charging and discharging parameters;

7. The controllers have the function of intelligently clearing faults, and all faults of non-controller hardware can be regularly cleared. Users don’t need any manual operation;

8. Using the Modbus Communication Protocol based on the RS-485 Communication Total Standard, the longer communication distance, the better communication protocol compatibility;

9. The device’s standard RJ45 interface can be connected to MT-50 Display Unit or PC Monitoring Software etc communication external equipments, which facilitates the users to view the controller’s running datas and modifies the controller’s parameters.
