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
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 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. 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)
16. 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 .
17. 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.
18. Output able or enable by manual ：Turn on or turn off the switch
by manual, The DC output will be shut off If choose switch off, The
DC output is normal if choose switch on , To avoid sparks when
connection the Loads to controller . User can choose switch off.
1.Optional temperaturecompensation function.
2.Optional RS232/RS485/USB function to communicate with computer and
SD card stocks parameters automatically.
