Our 440 Amp HVA Charge Controller for use with Wind Turbines, Solar Panels, and/or Hydro Systems is easily one of our most versatile, powerful controllers in our line of equipment. In our latest YouTube video, Wyatt gives instructions on how to change the different settings and some general troubleshooting tips.
Some of the features of the HVA include:
Wyatt shows how to change the controller voltage, extended divert mode, and dump point voltage and what isn’t user changeable!

With the residential, small scale wind turbine industry growing rapidly over the last decade, many new wind turbine blade sizes, materials, and designs have emerged onto the market. The options may leave you scratching your head so, with the release of our newest wind turbine blade, the Raptor Generation 5™, we thought we’d answer some questions you may have.
Blade Material:
Factors Affecting Startup and Torque:
Takeaway: small blades require high wind speeds to start spinning, that’s why they’re commonly used as sailboat wind turbines. Larger blades require less wind for start up and provide more torque to keep the turbine spinning under a load.
Number of Blades:
Small 3 blade turbines may take wind speeds of 12 mph* to turn the blades whereas our 7 blade Freedom wind turbines have start up speeds of 7 mph*.
(*Based on tower height and wind turbine placement)
Odd versus even number of blades:
On even blade sets: when the bottom blade passes the wind turbine mounting pole it creates a disturbance in the blade directly across from it, causing the blades to vibrate and shake. It’s nearly impossible to get these blades to balance. Balance is important to minimize vibration in the turbine.
Odd blades: the bottom and top blades don’t align and create a disparity that causes the turbine act as a flywheel to keep the turbine spinning.
I highly recommend watching our Wind Turbines for the Beginner How To Part One for more in depth explanations from Jeff on blade basics.
