Features
1. PWM mode off-overload
When the electrical power generated by the wind turbine and solar panels exceeds the needs of the battery and invert output, the control system must let out the superfluous power by discharging. Our controller is adopted the constant voltage charging mode-PWM to ensure the storage battery voltage to be on the floating charge voltage all the time, thus make full use of the electrical power and prolong the service life of the battery.
2. Regulate voltage automatically
With single chip, the machine can detect the battery charing voltage and current all time, meanwhile control the photovoltaic and wind turbine charing current to ristrict the batteries voltage and current, thus ensures the service life of the battery.
3. LCD display
You can look at magnitude of the the wind turbine charge current and storage battery state, then accommodate the magnitude and time of the user load based on battery voltage.
4. Wind and solar hybrid
Wind and solar hybrid system can be mutually complementary, thus make full use of wind and solar energy to generate power and reduce unbalanced or insufficient power supply resulted from a single energy for power generation.
5. Perfect protections setup:
