Detailed DIY Installation Guide

One of the greatest advantages of Primus Wind Turbines is the possibility of installing them yourself. While the process requires careful attention to detail and adherence to safety measures, it's achievable for those with basic DIY skills. Here's a detailed, step-by-step guide to help you install your Primus Wind Turbine.

Step 1: Site Selection

The performance of your wind turbine heavily depends on its location. Your site should ideally be open and exposed, with no obstacles that could block or disrupt wind flow. A site's wind speed and direction patterns, known as its wind regime, should also be considered. Assess your site's wind regime by researching local wind data or using an anemometer to measure wind speed and direction over a period of time.

Step 2: Assembling the Wind Turbine

The assembly process varies slightly depending on the model, but in general, you'll first assemble the blades and hub on the ground. Carefully attach each blade to the hub, ensuring that they're secured tightly. Next, attach the hub and blade assembly to the turbine body, again checking that all components are secure. While doing this, take care not to damage the nose cone or blades.

Step 3: Mounting the Wind Turbine

The wind turbine should be mounted high enough to avoid ground turbulence, typically at least 30 feet above any obstacle that's within 300 feet. This can be achieved using a tower or mast, which should be sturdy enough to support the turbine's weight and withstand high winds. Once the tower is secured, you'll attach the turbine, likely requiring help due to the turbine's weight. Ensure the turbine is correctly oriented and can rotate freely to face the wind.

Step 4: Wiring the Wind Turbine

After mounting, you'll connect the turbine to your power system. Each turbine model produces three-phase AC power, which is then converted to DC power compatible with your system voltage. This conversion is done via a rectifier, which should be installed as close to the battery bank as possible to minimize power loss. You'll run wiring from the turbine to the rectifier, and from the rectifier to the batteries, taking care to use the correct wire gauge and type for your specific setup.

Step 5: Setting Up the Charge Controller

A charge controller prevents your battery from overcharging by monitoring its voltage and reducing or stopping the energy flow once a certain voltage is reached. Connect the charge controller between the rectifier and the battery bank, ensuring that all connections are secure and that the controller is compatible with your battery type and system voltage.

Step 6: System Grounding

Grounding your wind turbine system helps protect it from lightning strikes and reduces the risk of electric shock. This can be done by connecting a grounding wire from the turbine and tower to a grounding rod, which should be driven deep into the ground. Local codes and standards for grounding should be followed to ensure safety.

Step 7: System Testing

Once everything is installed and wired correctly, it's time to test the system. Ensure the turbine starts spinning with the wind and that it's generating power as expected. Monitor the system for a few days to verify its operation, checking the battery voltage regularly to ensure it's charging correctly.


Embracing wind power with a Primus Wind Turbine can be a game-changer for your off-grid living experience or a significant step towards renewable energy utilization. With various models designed for different conditions and applications, and the possibility of a rewarding DIY installation, Primus turbines offer both flexibility and reliability.
