1. Application principles
1.1 The wind turbine should be installed in an open and flat area without barriers nearby.
1.2 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.
1.3 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).
2. The maintenance of the wind generator
2.1 Checking, cleaning and lubricating all rotating parts one time per year.
2.2 Before rain season, cleaning outside and paint antirust grease on the surface of all fixed connecting parts once a year.
2.3 Lubricating and maintenance bearing of generator one time per operating year.
2.4 Cleaning, rust removing and painting all exposed parts one time per every two years.
