Rutland HRSi Regulator


  • For Rutland 504, 914i, and FM910-4
  • 12 volt or 24 volt
  • For single turbine & battery bank
  • Add up to 160 watts solar


The Rutland HRSi hybrid charge controller is the latest in battery charge regulation from Marlec. Replacing HRS913 which was designed as a replacement for the SR200 shunt type regulators.

Designed for use on the WG914i, WG913 and FM910-3 wind turbines, it can also be used for the smaller WG503, WG504 or WG504e wind turbine.

For single battery banks only.

  • Regulates one Rutland WG914i, WG913, FM910-3, WG503, WG504 or WG504e plus up to 160W of Solar (Solar requires it’s own separate blocking diodes)
  • HRSi can be used on 12 or 24 volt systems and will automatically configure itself for the system voltage (when the correct connection sequence is observed)
  • Intelligent Microcontroller system delivers bulk and float phase for optimal charging
  • Pulse width modulated (PWM) charge control for maximum efficiency
  • Temperature Compensation automatically adjusts settings for varying termperatures to ensure maximum charging efficiency
  • Manual Shutdown Switch allows user to stop wind (& solar) from delivering power to the battery system (wind generator slows to an idle in this mode)
  • Built in blocking diode protects HRSi and Wind Turbine from other charge sources (solar requires it own diodes)
  • LED indicators for battery voltage and charging status
  • Simple installation: Wall mount with compression connection terminals
  • Max float voltage: 13.8VDC/12V; 27.6VDC/24V
  • Max bulk voltage 14.4VDC/12V; 28.8VDC/24V
  • Dimensions 5-1/8″ x 3-1/4″ x 1-3/4″ (130 x 80 x 42 mm)
  • One year manufacturers limited warranty from date of purchase

Typically in stock.
