1. Design for off-grid wind/solar hybrid street light system.
2. Integrated design of wind controller and solar controller.
3. Applicable to different kinds of batteries .
4. PWM stepless unload mode, which burn the excess power into
mosfet, making the battery charging in best status.
5. Digital intelligent control, With powerful imported MCU control
as the core device .To ensure Simple peripheral circuit structure,
And more flexible and powerful control method and control strategy.
6. Modular design with simple structure and easy maintenance.
7. LCD display function, visually display wind power , wind voltage
, wind current , wind turbine speed ,PV power , PV voltage , PV
current , battery voltage , battery power ,charge current .over
voltage ,under voltage ,over load, short circuit , night mode, DC
output modes etc.
8. Perfect protection function:Solar reverse charge protection,
Solar reverse connection protection,Battery overcharge protection,
Battery over current protection,Battery reverse connection
protection, Open battery protection ,Wind turbine automatic brake
and manual brake, over load protection and short circuit
protection, thus the system has higher reliability.
9. TVS Lightning Protection.
10. Wind turbine output voltage intelligent boost:The boost module
starts automatically when the wind turbine voltage is lower than
battery voltage , ensure that the wind turbine normally charges the
battery.The boost module shuts off automatically when the wind
turbine voltage is higher than battery voltage.
11. Impedance matching self-adaption :Due to internal resistance of
wind turbine, battery, load, According to the impedance matching
principle, The wind turbine will have maximum power utilization
rate and maximum power output only when the input impedance equals
to output impedance, with impedance matching self-adaption .This
controller enhances energy efficiency.
12. Combine the wind turbine open circuit with dump load ,over
rotational speed, over voltage, over current limitation：When the
total current of wind and solar is higher than limit current point
or battery is full , The PWM duty cycle of controller will be
decreased untill battery is fully charged. And then controller
disconnects the charging loop, the wind turbine will be on no-load
operation. In order to prevent wind turbine from propeller racing
.This controller is designed with over-current and over-voltage
limit, Controller will automatically start PWM voltage intelligent
dump-load function once wind turbine rotation speed or wind turbine
voltage is more than setting point. So avoid wind turbine constant
working in dump-load status, and increase the controller service
13. Maximum charging current limiting for batteryUser can set the
battery capacity and maximum charge current according to systems’
exact configuration . To ensure the battery service life.
14. Wind turbine and solar panel is intelligent complementary and
independant charging ：Wind turbine and solar panel is intelligent
complementary and independent charging . The solar panel adopts
open circuit protection , and wind turbine adopts open circuit ,
over voltage ,over rotation speed and over current protection
.Ensures the service life of system components .
15. The controller has two DC outputs specially designed for street
light system. Each DC output has 9 modes of controlling
light-control on and light-control off ( L- On and L-Off)
light-control on and time-control off (L-On and T-Off)
time-control on and time-control off (T-Off and T-On)
half power light-control on and light-off (H-L-On and L-Off)
half-power light-control on and time-control off ( H-L-On and
half-power time-control on and time-control off (H-T-ON and T-Off)
half-power constant on (H-Constant On)
