1. Application

A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home’s electrical system.

In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system.

Small wind systems for remote applications operate somewhat differently,and it needs batteries.

2. Structure and Main performance

TOPS turbines are made of strong cast steel that makes them durable. TOPS turbines can withstand harsh environments like strong winds and cold weather.Using high performance NdFeB permanent magnet, the alternator is high efficient and compact. The unique electro-magnet design makes the bonding force and cut-in speed very low.

4. Application principles

4.1 The wind turbine should be installed in an open and flat area without barriers nearby.

4.2 Off-grid wind turbine generating electric power is charged to the batteries group. When there is no wind, it consumes the electricity from the battery group. Therefore, after discharging, the batteries should be recharged timely, especially for lead-acid batteries. During the working, over discharging, over charging or after over discharging, the batteries cannot be recharged timely, the working life of the batteries will be reduced in above conditions. So, the users should regulate the consuming capacity of the electricity according to local wind condition and the electricity capacity generated by the wind generator.

4.3 After passing full wave bridge rectification, the 3-phase AC electricity generated by wind generator is output with DC power, usually are DC24V, 36V, 48V, 120V. The voltage of the battery group should be equal to the DC voltage of the wind generator (after rectification).

4.4 The input DC voltage of the matched inverter should be equal with working voltage of the wind generator (after rectification).

5. The maintenance of the wind generator

5.1 Checking, cleaning and lubricating all rotating parts one time per year.

5.2 Before rain season, cleaning outside and paint antirust grease on the surface of all fixed connecting parts once a year.

5.3 Lubricating and maintenance bearing of generator one time per operating year.

5.4 Cleaning, rust removing and painting all exposed parts one time per every two years.
