PV Controller

1、Overview
Photovoltaic controller is a device that effectively controls the status of battery charged by solar energy and outputting to load so that the battery works within a safe range of operating voltage and current. Its controllability directly affects battery service life and system efficiency. Solar charging and discharging controller is widely applied in mobile telecommunication base station, microwave station, postal and telecommunications, cable transmission, railway telecommunication, and is also used to supply power for pasturing area, frontier defense, coastal army and mobile occasions.
As solar panel is very expensive, maximizing use of solar panel is one of the key technologies of the controller. This controller is designed on basis of German concept, i.e, single-point method”, and under double closed loop control (voltage and current double control). Furthermore, its following speed is fast and it is on the leading edge in domestic market. It is found that 15% of solar panel will be saved under the same condition. The controller is able to record daily and monthly output and discharge and ensure no data lost when out of power. Solar power controller is also equipped with a micro-computer chip and non-contact control technology, and has various protection functions.
2、Characteristics
The inverter adopts Germany design thought,that is "one point",and is double close-loop control(voltage and current double control),can make maximum energy of solar cell charge up to battery,which will enhance the efficiency
The display part adopts LED or LCD mode ,which can carry on realtime monitoring and display to battery voltage,load Load short-circuit value,environment temperature
The system parameter can be programmed and set including battery parameter,PV cell parameter(reservation),system parameter,time parameter
The controller is of a series of voice、light warning and protection function including over charge,over discharge,over load,short ciruit reverse connection over voltage,over heat or first shutdown,second shutdown and so on
Setting up parmeters with password protection function,which can effectively prevent non-misoperation of professionais on the controller
Supply the normal connection of RS232/RS485
Possess the function of RTC it,can send and monfidy the current time clock parameter We can fit diversified class arrester according to the different requirement
Temterature compensation
Supply light control,diesel generator,standby power supply and etc if the system needs
3、Application field
Solar controller transform the solar energy into electricity power through the solar cell and store,is widely used in mobile communication base stations,microwave stations,but also provide power supply for the pastoral areas,border,island units,and mobile occasions and so on.
