Rutland 914i Windcharger Wind Generator

Rutland 914i Windcharger Wind Generator

Buy the Rutland 914i Windcharger Wind Generator for Sailing boats and Yachts Online, UK. 

**This is a special order product - please call for lead time to avoid disappointment**

  • Rating: 140 W in a 11 m/s (24.6 mph) wind.
  • Rating Max: 262W
  • Voltage: 12 or 24 volts DC.
  • Rotor Diameter: 0.91m
  • Cut In Windspeed: 3.1 m/s (6.9 mph)

Designed for marine use and for use on narrowboats.

The Rutland 914i builds on the success of the Rutland 913, utilising Maximum Power Point Tracking (MPPT) technology to perfectly match the generator performance to the turbine speed achieving a higher efficiency and thus more power generation. This innovation has enabled the Rutland 914i to retain the compact diameter of the 913 whilst being capable of capturing up to 30% more energy.

Rutland Charge Controllers

See Brochure here

HRSI Regulator

Uses Pulse Width Modulation (PWM) to protect battery from overcharging by tapering charge as battery becomes full and reducing the Windcharger speed. Includes LED indicators for charging status and battery voltage. Also includes facility for connection of up to 160W of solar. Features windcharger shutdown switch.

  • Pulse Width Modulation (PWM) regulation is now more finely controlled using the latest programmable microcontrollers
  • The HRSi monitors battery voltage and uses PWM to prevent overcharge.
  • As peak voltages are reached the HRSi regulates the current from the wind & solar chargers gradually reducing the charge to float stage level.
  • This feature gradually reduces the speed of the turbine to an eventual “idle” thus extending the working life of the windcharger.
  • As the battery discharges the wind turbine responds by increasing speed to deliver more power.
  • Solar power is also tapered in the same way.
  • Intelligent Microcontroller system is programmed to deliver bulk and float phase charging.
  • This feature ensures that batteries are optimally charged, especially when unattended.
  • LED indicators keep the user informed about battery voltage levels and charging status
  • The HRSi regulator can charge a single bank of batteries at either 12 Volts or 24 Volts.
  • Manual shutdown switch allows the user to stop the wind & solar chargers from delivering power to the battery if required.
  • The windcharger slows to a “idle” in this mode.
  • Easy to connect terminals to interface windcharger, solar panels & battery connection in one.
  • Temperature compensation automatically adjusts the settings of the regulator to take account of varying temperatures thus ensuring maximum charging efficiency in all conditions.
  • Built in blocking diode avoids conflict with other charging sources to the same battery. (See note 1 below)
  • Automatic voltage detection for 12 Volt or 24 Volt systems. (See note 2 below)
  • Built-in charge fuse protects the wiring circuit in the event of accidental reverse polarity connection. (See note 3 below)

HRSi Installation: 

1. Solar panels must be fitted with diodes 

2. Batteries must be connected first for auto voltage detection and setting  

3. Care should be taken when connecting the HRSi, as with all electrical devices, reverse polarity connection will cause damage to the HRSi.
