and manual brake, 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.
High-voltage wind turbine intelligent buck: The buck module starts
automatically when the wind turbine voltage is higher than battery
voltage , The controller real-time tracks maximum power of wind
turbine and Real-time limits the winding current of wind turbine
.To solve the problem of overheating of wind turbine.
With press key.User can choose the intelligent boost or intelligent
buck according to performance of wind turbine . To ensure the
system work more reliable andmore efficiently.
11. Impedance matching self-adaption:Due to internal resistance of wind turbine, battery, 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 life.
13. Maximum charging current limiting for battery: User 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. Wind turbine charging able or enable by manual:Turn on or turn off the charging switch by manual, The wind
charging is shut off if choose switch off, The wind charging is
normal if choose switch on . To avoid sparks when connection the
wind turbine to controller , User can choose switch off .
16. Solar charging able or enable by manual:Turn on or turn off the charging switch by manual, The solar
charging is shut off if choose switch off , The solar charging is
normal if choose switch on .To avoid sparks when connection the
solar panel to controller, User can choose switch off.Optional Functions:
