Product introduction:

This controller is designed for DC power supply system, small and medium-sized pv modules power system, using a dedicated computer chip to realize the intelligent control, all chips adopt industrial level, can be used in harsh environment.

Meanwhile 
system offers specific indication for the charge, load , sorts of failure and various protections such as short circuit, over-load, over charge, particular anti-reversed polarity protection and so on, the controller used computer chip to sample the parameter of the battery voltage, photovoltaic cell voltage, discharge current and environment temperature.

According to the battery’s character, realized the accurate 
control to discharge rate, correction of the temperature compensation through special control model calculation.charging with the intelligent PWM dim way and charging compensation in accordance with the current temperature of the battery, compensation factor is 3mv/℃/unit.LCM could show all of the parameters and modes. 

Offer as many as five LED adjust way with lattice pattern to guarantee the battery works in the best status which could lengthen the service life of the battery. The controller has many work modes to satisfy different customer’s request. Dial switch need to adjust if adopting different voltage system.

Features:

1. The controller carried with LCM module which can display system status and parameters

2. Begin to ascending charging automatically when the voltage of battery below the ascending charging recover voltage

3. Temperature compensation become more accurate due to Double temperature sensors design,inner temperature sensor test the inner temperature of the controller, outer temperature sensor test the outer temperature of the controller.

4. The controller could figure out everyday’s power of charge and dischargewhich make user assess the controller and entire system more easily

5. With the charging current overload protection function, the controller will reduce the charge current to protect the charging circuit after it surpass the rated current.

6. A equalizing charge every 30 days in order to prevent battery vulcanization

7. Industrial-grade chips and precision components makes the controller can operate in any harsh environment

8. Design of double MOS series control circuit and PWM dim control make the charging efficiency increased greatly

9. The setting parameter possess the saving function which makes the parameter won’t be erased after losing the electricity and system become more reliable.

10. Three kinds of load work mode: purely light-operated, light-operated+time PV Instruction, Load instruction, Temperature compensation controlled, long-term on mode.
