2. Wind Turbine Assembly Installation on site is simple, mainly including mounting blades on the hub, securing the hub to the turbine body, installing the nosecone on the blade hub and mounting wind turbine on the pole. Please install the whole turbine in accordance with the following instructions. 2.1 Mounting Blades on The Hub ①Check if all components are in good condition. ④Pass the hex bolts through from the back side of the hub.
2.2 Connecting lead wires to Wind Generator ① wind generator main body ④Connect the three-phase lead wires into ②Unscrew cable cover. ③ Pass the wires through the cover. ⑤Screw up the cable cover. ⑥Screw up the waterproof cover.
2.3 Generator and Tail Vane Assembly ①Wind generator of corresponding generator. ④Bolts and washers ②Tail vane ③Insert the tail vane into the groove of the back of generator, pay attention to the flange bore position is position is corresponding to the hole of back of the of the generator. ⑤ Tighten the bolt to35N.m 14 ⑥ Decoration cover,screws and locknuts.
⑦ Snap the cover to the back of generator ⑧Tighten the cover by screws to 5N.m ⑨Assembled. 2.4 Mounting Turbines on The Pole ①Pass the cable through from the pole ②Connect the turbine to the pole by bolts. 2.5 Hub/Blades and Generator Assembly 15 ③ Place flat washer, spring washer and nut, tighten the nut to 60N.
① The nosecone and accessories. ②Place the hub with blades onto the rotor shaft ③ Fully tighten the nut to 500N.m and “spin” it completely onto the turbine alternator shaft, then place in sequence of flat washer, spring washer and nut. ④Snap the nosecone into position over the outside edges of the blade hub and tighten by screws to 7 N.
3 Tower Installation 3.1 Siting An ideal location for wind generator is required with stable speed and direction of prevailing wind. Small changes in wind speed and direction can have a dramatic effect on power production. In general, the higher the tower, the greater the wind speed and ultimately power production are. Therefore, the site of your wind turbine should be carefully considered.
• The installation distance between two turbines should be 8-10 times of the rotor diameter. • Installation site should be complied with local regulations. Safety must be the primary concern when selecting the mounting location. Even if installing the wind turbine in a less than ideal location, don’t attempt to mount the turbine while blades are spinning. Safety has precedence over efficiency.

Special installation 2: flat roof top Explanations: 1.This installation is workable for flat roof top. 2.The wall or ground of rooftop should be concrete or solid wall. 3.The installations could be both used expansion bolt to fix the supporting structure. Dimension requirement: ① Distance from rotor centre to roof top ≥ 6 m ② Supporting point should be 1.
4. Wire Size Selection All electrical systems lose energy due to resistance in conductors: the wires. • The larger the wire is , the less resistance and the loss are • Resistance losses will also increase with increasing current; therefore, if you installation is at a high wind site, it may be worthwhile to go with a larger size wire to lower the loss and enhance the output of wind turbine.
5. Troubleshooting 5.1 Wind Turbine Troubleshooting 5.1.1 Wind Turbine Vibration Wind turbine vibration is mainly caused by the following factors: 1) The blades mounting bolts get loose and need to be tightened; 2) The surface of blades gets frozen and needs to be removed; 3) The blades have been distorted, defected and need to be replaced.
5.1.3 Rotation seed Dramatically Decreases Wind turbine rotation speed dramatically decreases under heavy wind condition, which can be mainly divided into normal deceleration and abnormal deceleration: 1) Turbine normal deceleration is due to wind turbine over-speed protection, for example, dump load, electromagnetic braking and blades aerodynamic braking. These are regular protection ways to protect the wind turbine and the whole system in high wind.
5.2 System Troubleshooting 5.2.1 Off-grid wind and solar hybrid system 5.2.1.1 Solar Output Voltage Too Low or No Output 1) Check whether solar panel lead is short circuit, circuit break, open circuit or not. 2) Check whether solar panel is damaged or accumulated too much dust, etc. 5.2.1.2 Abnormal charging Wind turbine does not charge battery is mainly caused by: 1) Wind speed is too low to reach cut in point.
5.2.2 Grid-tied Wind Turbine System 5.2.2.1 No power feed into grid 1) wind speed is too low, wind turbine still haven’t reach it’s cut-in wind speed, so no current generated in less than 2.5m/s wind speed. 2) Wind speed is too high, wind turbine output voltage reach the over-voltage point, controller short-circuit braking system protect the wind turbine and the whole system, the system will restore automatically when the wind speed decrease.
6. Maintenance Although this wind turbine has been designed for high reliability, to run for 15 years without any maintenance, reliability and performance will be enhanced if you periodically inspect your system. IMPORTANT: It is suggested that putting down the pole and making wind turbine short circuit before some extremely bad weather, such as typhoon, in case of some unpredictable accidents happen. The following situations need regular maintenance: No.
Appendix I Definition of 50m/s survival wind speed of wind turbine This Ramsond wind turbine is strict in accordance with following standards: GB/T 10760.1 Generator of Off-grid Wind Turbine Generator System Part 1:Technology condition GB/T 13981-2009 Design General Requirements for Small Wind Turbine Generator System GB 17646 Safety of Small Wind Turbine Generator System GB/T 19068.1 Off-grid Wind turbine Generator Systems Part 1:Technology condition JB/T 10399-2004 JB/T 10402.
From above explanation, the survival wind speed of Class III wind turbine is: =1.4 -1.4 *7%=1.4*37.5-1.4*37.5*7%=52.5-3.68=48.82m/s (＜50m/s) So this is why the survival wind speed of this wind turbine is 50m/s.
