The latest wind & solar charge controller development from Marlec Eng, the HRDi evolves from and improves on the successful HRDX controller.  The contemporary design meets the needs of ever increasing power demands and features a user selectable digital display.  The controller incorporates Pulse Width Modulation (PWM) technology to regulate battery voltage preventing overcharge.

Charge control and dual battery bank charging for use with Rutland 503, 504, 913 or FM910-3 Wind Generators and up to 160W of solar PV panels.

Features

• Clear alpha-numeric digital LCD screen with user display options

• Connectable to two independent battery banks with voltages shown on display

• Push button activated and timer controlled back light

• Auto-configuration to 12 or 24 V supply

• Latest technology micro controller based system shuts wind charger down when batteries are full

• Wall mounted modern molded structure with easy access connection ports

• Manual shutdown switch

• Bulk and float phase charge control indicated on LCD

• Temperature compensation of charge voltage using internal sensor or via the external temperature  sensor supplied with the unit.

• Optional remote display can be added via dedicated port (to follow later this year)

• Accepts up to  AWG 9 (6 mm˛ cable or SWG 11)

Technical Features

• The PWM electronic charge regulator tapers charge to the battery to limit current and avoid battery overcharge. When regulating the Wind Generator speed is reduced.

• Standard regulator cut in level is 13.8 Volt and fully on at 14.4 Volt for 12 Volt systems   (24 Volt= 27.6 Volt - 28.8 Volt).

• Built in charge splitter for 2 isolated battery banks.

• LCD digital display of:

  • Windcharger current

  • Solar current

  • Net charge current

  • Battery 1 voltage

  • Battery 2 voltage

• Charge source shutdown switch

• Use with Rutland 504, 503, 913 or FM910-3 plus up to 160w of solar panels.
