4. Universal Function
4.1 Adaptive Impedance Matching of Wind Turbine & Load
Wind Turbine , battery and load all have internal resistance. According to impedance matching principle, only when
Input. impedance equals to output impedance, power utilization would be maximal , The energy utilization will be
improved to the utmost extent by adaptive impedance matching of controller .
4.2 Control mode of Wind Turbine Open Circuit & Dump-loading ; Over Rotate Speed Limiting, Over Voltage &
Over current Limiting
Traditional wind solar hybrid controller : When total current of wind & solar is higher than limiting current, battery
power increases . The excess energy will be dumped by PWM. Wind turbine rotate speed lower. And the excess energy
is consumed in mosfets or resistance . This leads wind turbine to heat , shortens wind turbine and controller
’s working life.
This professional wind solar hybrid contoller :When total current of wind & solar is higher than limiting current, battery
power increases .PWM duty cycle of charging circuit is decreased until charging is finished .When charging finished.
Current circuit disconnected , wind turbine has no load ,In order to prevent wind turbine from a very quick rotate
speed , This professional controller provides the function of over rotate speed limiting and over voltage limiting,
Once the rotate speed or voltage exceeds what you set on the controller , The controller will start PWM smart
dump-loading automatically. Prevent wind turbine from working in unloading state for long time . This is good for
both wind turbine and controller .
4.3 Battery Maximum Charging Current Smart Limiting
Traditonal wind solar hybrid controller : Different wind solar hybrid systems need different capacity batteries;
Different capacity batteries have different maximum current, Traditional wind solar hybrid controller has no
settings for batteries maximum charging current , or have wrong settings , leads over current , shortens batteries
using life .
This professional wind solar hybrid controller : User can set the capacity of battery ,The professional
controller can calculate the maximum charging current intelligently according to user
’s settings, Protect batteries .
4.4 Manual Brake
4.5 Using or not using wind turbine to charge battery could be set manually
User can choose whether use wind turbine to charge the battery ,Set wind
“M-SW: ON” . Wind turbine charging is
normal .Set wind
“ M-SW: OFF” . Wind turbine charging is prohibited . Before connecting the wind turbine , User could
first set wind
“ M-SW: OFF” manually to prevent sparks .
4.6 Using or not using solar panel to charge battery could be set manually
User can choose whether use solar panel to charge the battery ,Set solar
“ M-SW: ON”, Solar panel charging is
normal . Set solar
“ M-SW: OFF” , Solar panel charging is prohibited. Before connecting the solar panels . User
could first set solar.
“M-SW : OFF ” manually to prevent sparks .
4.7 LCD display multi-level menu ; Intelligent button settings ;
The controller with LCD screen supports multi-level menu viewing. Users could set lots of parameters through
buttons.
The desigh of this controller is humanized .
