Precision-molded, aerodynamic fiberglass blades ensure quiet performance and minimal vibration. Turbine output is 3 phase AC, reducing power loss over longer wire lengths, that is then converted to DC at the MPPT controller. Microprocessor-based controller provides voltage regulation of the 12V output, peak power tracking, and silent stall control in high winds (see more info below). At sea the increased blade tip angle improves ability of blades to both engage wind at low speeds as well as shifting the point at which blades would typically “flutter” in high winds to a point above the rotational speed allowed by the MPPT controller. In port, hysteresis braking locks the turbine in a silent regulation mode once the batteries are fully charged, preventing the turbine from fluctuating in and out of regulation mode. The result is quieter, more unobtrusive operation both under sail and when docked. The tail-fin of this marine turbine model is designed to better stabilize the unit in marine wind environments.

Turbine specifications:

• Number of blades: 3
• Blade diameter: 52"
• Voltage: 12
• Watts: 600W Turbine. (450W Turbine & MPPT Controller used together)
• Cut-in speed: 4mph
• Overspeed protection: Electronic @ 1400rpm
• Dimensions: 7"L x 5"W x 10"H

The included Maximum Power Point Tracking (MPPT) charge controller enables the 600 watt marine turbine to achieve its highest possible performance by periodically tracking the maximum power point of the turbine’s output. The controller features a corrosion and water resistant heat sealed casing to insure longevity in the marine environment. MPPT controller output  featuresa temperature-compensated three-stage battery charging regulator.
