solar controller

Specifications

Application area:

The solar PV controller is another key devices of a off grid solar power system, it charges for battery while solar panel get solar energy; The controller makes active controlling of the charging from solar panel to battery, and also discharging from battery to devices, make sure the battery work in safety conditions of its voltage and current; The controller performance would make direct effects to life span of battery bank and system efficiency

Technical Characters:

Tandem PWM control Technology, High efficiency

A "point-type" control and current and voltage pairs of closed-loop control, maximizing charging capacity from PV module to battery, improving charging efficiency

Part of unit has LED, LCD display, timely monitoring and displaying battery voltage, load & charging current, daily power generated and discharged amount, total power generated and discharged amount, load shortage times, environment temperature, AC output voltage & current and so on.

System is programmable for parameters of battery, PV module, system and time.

Part of units has RS232/RS485 connect interface

System has RTC function, would be able to check current time and manage to change the time parameters

Man-machine interface LCD could display working parameters and faults for some units

Setting to open/off machine function

Charge and power use in the same while when day time, reliable output voltage and frequency

Multi protection functions, over charge & discharge, over load, shortage, Reverse polarity, over voltage, over heat protections or warning buzzer. And all protection would be auto recover itself. Safety meets: IEC61173, IEC 60529, IEC 62109 and so on
