The latest wind & solar charge controller development from Marlec, 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 split charging for use with Rutland 503, 504, 913 or FM910-3 Windchargers and up to 160W of solar 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

Autoconfiguration to 12 or 24 V supply

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

Wall mounted modern moulded 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 external sensor also supplied

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

Accepts up to 6 mm² cable (SWG 11 or AWG 9)

Technical FeaturesThe PWM electronic charge regulator tapers charge to the battery to limit current and avoid battery overcharge. When regulating the Windcharger 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.

Designed for use with Rutland 504, 503, 913 or FM910-3 plus up to 160w of solar panels.
