100% solid state controller (no mechanical relays or solenoids).

Curved water heating allows faster heating with more surface area.
Can be used with wind turbines and solar panels.
Can be connected as 24 Volts 300 Watts or 12 Volts 80 Watts.
Standard American water heater element replacement for on or off grid applications.

The hub groove and the blade are tightly designed to make the matching between the blade and the hub more precise.
The built-in copper sleeve insert of the blade does not damage the nylon fiber when the bolt is tightened, making it difficult to deform or break.
The wind turbines uses a flange connection to make it safer and more reliable.
High wind energy conversion rate, increasing annual power generation.
The surface of the hub is oxidized to make the surface less prone to corrosion and durable.
