3KW off/on-grid working system wind turbine
Application
Domestic wind turbine is a distributed power generation. Domestic wind turbines are mainly used in rural areas, pastoral areas, mountainous areas, developing large, medium and small cities or buildings near commercial areas to meet the power demand of local users. With the continuous introduction of relevant supporting policies by the state, domestic wind turbine, as a kind of distributed power generation, has become a new and promising power generation mode and energy comprehensive utilization mode with its small modular, decentralized, efficient and reliable power generation mode arranged near users.
Wind turbine is an equipment to convert wind energy into electric power which is charged into storage battery group or interface to utility grid. It can be widely used in rich wind areas.
Now we have 48v-240vdc off grid working system, wind solar hybrid system. It is capable of providing power for lighting, TV, washing machine, refrigerator, small water pump, air conditioner, telecommunication equipment and so on.
On grid working system 120v-500vdc: wind turbine output 3 phase AC power, PWM on grid controller convert AC to DC and supply steady DC voltage to grid tie inverter. The power can be use for home appliance, extra power interface to the utility grid.

4. for urich wind place , we recommend Fd6-5kw wind turbine . The larger blades rotor diameter has lower ratedwind speed . Also the installation blade angle and make the largest angle . This way wind turbine will workbetter in low wind speed condition
The wind-solar complementary multiple combined series power generation system is to install multiple low-power wind turbines in the same place, charge multiple supporting large-capacity battery packs at the same time, and control the output uniformly by a high-power control inverter. The advantages of this configuration are:
(1) Small wind turbines have mature technology, simple structure, stable quality, safety and reliability, and economic benefits;
(2) Easy to assemble, disassemble, carry and maintain, and easy to operate;
(3) In case of maintenance or fault shutdown, other units will generate power as usual, without affecting the normal use of the system;
(4) Many sets of wind-solar complementary power generation systems naturally become a scenic spot and a green power station without environmental pollution.
