HRDi Wind Charger Regulator 12 or 24V

The HRDi Charge Controller is the latest wind and solar regulator from Marlec. The HRDi has evolved from and improved on the successful HRDX controller. It provides Charge Control and Power Splitting for off-grid system with two independent batteries, such as the cranking battery and leisure battery on a boat. The contemporary design meets the needs of increasing power demands and features a useful digital display that shows the amount of generated free power, along with the battery state of charge. It is designed for use with the Rutland 504, 914i or FM910-4 Windchargers and up to 160W of solar panels.

HRSi Hybrid Charge Controller 1224V

Charge Controller Features:

The HRDi conveniently brings together a Rutland Windcharger voltage regulator
with an input for up to 160Watts of photovoltaic panels in a single easy to install device. Multi-stage charge control delivers appropriate charge levels required to ensure your batteries get the maximum power they are able to retain and remain float charged.


  • 12 or 24V
  • PWM-regulation (series type)
  • Pulse Width Modulation (PWM) regulation is now more finely
    controlled using the latest programmable microcontrollers. PWM
    regulation monitors battery voltage to prevent overcharge. As peak
    voltages are reached the HRSi tapers the input charge from the
    wind & solar chargers gradually reducing input 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.
  • Clear alpha-numeric digital LCD screen with user display options
  • 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.
  • Connectable to two independent battery banks
  • Wall mounted.
  • Push button activated and timer controlled back light
  • Designed for use with Rutland 504, 913, 914, FM-910-3 plus up to 160W of Solar.
  • Easy to connect terminals to interface windcharger, solar panels & battery connection.
  • Temperature compensation to optimise charging in all conditions Using internal sensor or external sensor also supplied
  • Automatic Voltage Detection 12-24V (Battery Must Be Conected First)
  • Latest micro controller based system shuts wind charger down when batteries are full

These Hybrid Charge controllers are an ideal way to get your Solar & Wind Hybrid System charging your battery bank in a controlled manner thus protecting and extending your battery life.
