(1) The controller adopts wind and solar generation separately or hybrid combination as input power.

(2) Adopting self-accommodated power control technology, the controller can raise voltage when the wind speed is low, making the wind turbine generator charge the battery at a low rotational speed; and limit the output power in case it damages the battery when the wind speed is high .

(3)The controller has advantages such as steady voltage and current of high precision, little ripple, high efficiency, wide input voltage range and so on.

(4) The controller can charge the battery in accordance with steady voltage and current mode, which ensures that the battery can be fully charged without damage. It also maintains constant voltage float charging, and compensate electricity leakage losses at any time.

(5) The controller can judge daytime and night according to the voltage of the solar panel, then turn on or turn off the light automatically. Lighting duration can be set to a fixed time or adjusted automatically according to the battery charge condition.

(6)When the battery power is too low, it can switch off the load line, which will prevent damage caused by over discharging.

(7) The controller has perfect protection function, such as solar battery reverse polarity protection, battery power over-low protection, wind generation input/output overvoltage protection, wind generation input/output over current protection, wind generation speed brake protection etc.
