HRS Charge Controller

HRS Charge Controller

Quick Overview

The HRS Regulator incorporates electronic Pulse Width Modulation (PWM) technology to regulate battery voltage to prevent overcharge. This generation of voltage regulation includes speed limiting to the turbine when the battery is full, which increases the lifetime of the windcharger. The HRS503 is designed for use with the Rutland 504 and previous Rutland 503 models.
View Options



  • The PWM electronic charge regulator tapers charge to the battery by gradually limiting windcharger current to avoid battery overcharge.
    • When regulating the Windcharger turbine speed is gradually reduced until finally running at just a slow "idle"
    • As fully charged batteries are more likely to occur in high winds this slow mode of operation is safer and reduces wear
  • A solar panel with a maximum rating up to 100W may be connected in parallel with the windcharger.
    • Note that a blocking diode must be fitted to the solar panel to prevent it from drawing current from the windcharger
  • Built-in blocking diode protects the HRS and Windcharger from other charge sources to the same battery, eg engine charging
  • The HRS regulator can charge a single bank of batteries in parallel
  • 2 Tri-colour LED’s indicate,
    • Approximate level of battery voltage between 11-14V.
    • Charging status – either charging, regulating or both charging and regulating
  • Regulating cut-in voltage 13.8V, Maximum charge voltage 14.4V (+/- 2%)
  • Simple wired connection via 3 flying leads
  • Net Weight: 0.12Kg Packed Weight: 0.2Kg
  • Carton Dimensions:160×110x60mm

Technical Features
