First step--Choose place
Small changes in wind speed can have a dramatic effect on power production. The sitting of your wind turbine should be carefully considered. Each installation is different and is often a compromise among tower height, distance from the battery bank, local zoning requirements and obstacles such as buildings and trees. 
In general the higher the tower, the greater the wind speed and ultimately power production. However, towers are expensive and can easily exceed the cost of the turbine. 
The MIN recommended tower height is 25 ft (7.6 m) on open ground or 20 ft (6 m) above nearby obstructions. Try to locate the wind turbine in the “cleanest” turbulent free air as possible. Turbulence will reduce the efficiency of the wind turbine and may accelerate wear on rotat- ing components.
Safety must be the primary concern when selecting the mounting location. Install MINI so there is no possibility of accidental contact with rotating blades even if it requires installing the wind turbine in a less than ideal location. Safety has precedence over efficiency.

Second step--MINI connection
1.The recommended way to connect the turbine to your battery bank is to wire the turbine directly to its own set of battery posts. This will allow the turbine to operate independently. The MINI’s internal regulator will monitor the battery and maintain the charge as necessary. figs. 9 and 10 represent typical single turbine installations. fig. 10 includes an up-tower junction box for National Electric Code compliance. Contact us for more information about this configuration.
The junction box may be installed close to the top of the tower to ease installing a Lightning Arrestor. Typically installing the box will require drilling holes in the tower to install the box – be careful not to compromise the tower strength.

2.Some charging sources (solar panels, fuel-powered generators, additional wind generators, etc.) connected to the same system may cause interference with the MINI internal electronic and result in pre- regulation. The interference will not harm the turbine; it will just cause it to spin slowly as if “braked” or it may stop the turbine. If this occurs, test for possible interference by  disconnecting the other charging sources to determine the possible cause. If possible wire the turbine and PV panels to their own set of battery posts.

Third step--Grounding connection
Proper grounding of the MINI provides protection to individuals and equipment by eliminating the possibility of dangerous voltage potentials.
There are two aspects to grounding any electrical system – grounding one of the conductors of the electrical system and grounding all metal structures in the system that may have a voltage potential caused by an electrical failure.
In a typical MINI installation grounding one of the conductors is accomplished by connecting the MINI negative (black) conductor to an “earth” ground close to the battery bank. Installation and connection to grounding rods is described in the following section on Tower Grounding.
Grounding the metal structures in the system – typically this includes the tower and turbine – is accomplished by connecting the structures together using conductors of the same size as the positive and negative conductors and then routing a conductor to an earth ground。

Forth step--MINI installation
The following are general guidelines for the installation of MINI. Because each wind turbine installation is unique,specific step-by-step installation instructions cannot be provided. However, before attempting final installation the following basic steps should be completed.
• Completely review MINI Owner’s Manual.
• Select tower and site and install tower.
• Determine wire size.
• Design system including batteries, switches, circuit breakers – draw wiring diagram.
• Obtain required components.
• Assemble turbine .
Once these steps are completed, final assembly is fairly simple and consists primarily of making good electrical connections according to the wiring diagram and mounting MINI on the tower.
