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.
