Product Details

Rutland FM910-4 Furlmatic Windcharger

Rutland Windchargers are without doubt one of the most unique and versatile battery chargers in use throughout the world.
The Rutland FM910-4 combines our proven furling tail systemand latest 3 phase generator technology with a new aerodynamically shaped body style. This combination of the established and the modern means that our customers can be sure of great power performance and reliability over many years service. Primarily designed for land based applications, the Rutland Furlmatic has been used worldwide to provide year round power generation

Efficient power conversion
Generate greater ampere hours in real wind conditions than turbines of equal and often larger diameter
Automatic ‘furling’ tail fin directs turbine out of wind above 16 m/s for gale protection
Low friction 3 phase alternators give a smooth and silent output
Computer designed efficient aerofoil blades
EEC directive 89/336/EEC compliance ensures no radiated interference
Automatic thermostat protection in prolonged gales
Durable materials for excellent reliability and product longevity

Wind Power

Rutland Windcharger System

Rutland Windchargers are micro wind turbines used for battery charging at both permanent and temporary sites. They are a convenient and cost effective alternative power supply particularly for isolated locations where the grid is unavailable or too expensive to install. Rutland Windchargers are a long established brand of reliable turbines and voltage controllers.
• Eliminate or reduce site visits for battery changeovers
• Maintain Continuity of power for essential datalogging or communications
• Replaces the need for grid connection, fuel or generators at remote sites
• Combine with solar panels for year round balance of energy generation
• Use the power generated at 12V for DC equipment or connect to an inverter for 230V low energy appliances, eg laptops.

Rutland Windchargers

Both Windcharger models are highly efficient at converting the power in the wind to electrical energy. They feature the Rutland low torque alternator and fine profile aerofoil blades delivering power from a very low wind speed whilst being
robustly constructed to give long service at unattended sites.

Rutland Windcharger Voltage Regulators

A voltage regulator is recommended with each windcharger. This electronic device provides an easy to connect interface between the windcharger, solar panels and battery whilst also providing protection from overcharging. Two models are available with individual design features but both are PWM, pulse width modulation, controlled which tapers the charge current until eventually slowing down the speed of the turbine to an idle. A shutdown switch allows the user to isolate charge current for maintenance or battery changeovers.
