The controller is designed specifically for hybrid wind solar street light system, which can make the wind solar hybrid street light system of various resources to achieve the best configuration, of course, the controller with some simple Settings can also be used in household system.
Intelligent design succinct structure,powerfulcontroll, stable performance, safety and reliability of the products.Choose MPPT Wind turbine charging ways, charging more efficiency than ordinary PWM way more superior. The boost charge function, solve the low charging efficiency problem of low wind speed (optional). Professional digital intelligent control.
Features：
1.The Wind turbine charging part and Solar charging part are independent of each other, can make Wind turbine controller or solar controller using independent (As a Wind turbine controller cannot use light control function).
Wind turbine charging adopted booster MPPT technology, which makes under low wind speed, the Wind turbine's electricity can still be used;
In the high wind speed or the Wind turbine of power is beyond the scope of the battery and load absorption, the controller immediately launched the stepless unloading function,protection system of the equipment.
Solar charging using in series MOS tube PWM technology, which makes the controller power consumption is small, the system more stable.
2.Discharge part working mode can be set, light control mode, time control function etc, The user can be set up according to the requirements on its own combination.
3.Manmachine interface of the controller USES a custom LCD screen and four key operation mode, the user to use simple and easy to use, popular and easy to understand, convenient and quick.
4. The controllers with perfect protection function, including: lightning counter-attack, solar charger, over-voltage automatic braking, storage battery reverse connect and open protection, etc.

Technical note:
In offgrid system, there is always a pair of contradictions that produce energy source and energy absorption of load does not match the problem, may be the following situation:
1. The power supply can be issued under the condition of sufficient electrical energy of the load is not likely to work and the battery power is full, so this time we need to send power electricity do discharge processing, otherwise may cause permanent damage to the equipment;
2. In the power supply does not have enough electric power support is likely to appear when battery power is rarely lead to load can not have normal work, so we also need to improve power generation capacity in this situation.
In our wind solar system, solar panels power relative to the Wind turbine power is very stable power supply, so we had a wind solar hybrid controller mainly for Wind turbine design the booster MPPT charging technology and step-less unloading function, and in view of the solar panels still take simple and efficient PWM charging technology.
Booster MPPT mainly for most of the time in many parts of the wind power is not enough to support a generator to the condition of the battery charging, specific working principle is: the Wind turbine under the condition of wind speed reach the rated wind speed, the resulting voltage and power are not reach the rated power, we through realtime acquisition Wind turbine by means of booster circuit of voltage and current from the boost voltage to the battery voltage to the system requirements, using the software MPPT algorithm make the Wind turbine of power use as much as possible.
Stepless unloading function mainly aimed at the first case, when don't need additional energy, will generate the energy consumption of the Wind turbine on unloading device, the controller dedicated connection port of unloading device, the user can be selected according to actual condition when the choose and buy, we suggest in good wind conditions, such as coastal and western is empty,you must configure unloading;In some inland areas where wind conditions in general, we also recommend that try to configure unloading
