Reprogramming for Other Baery Types
A PC App and Marlec Controller Interface Lead are available for programming
parameters for use with other baery types. Features include Voltage levels,
termperature compensaon and low temperature shutdown. Contact Marlec for
availability.

HRDiLayout & Main Features Congratulaons on purchasing Marlec’s HRDiCharge Regulator.
This is the latest technology for over charge regulaon of Rutland wind turbines and
solar panels. It is designed for use with Rutland 50”X” and 91”X” series models and
≤160Was of solar panels charging up to 2 separate baery banks.

Quick Start Guide
The sequence of connecon is crical to the voltage set up of the HRDi. Follow
these instrucons carefully to ensure no connecons are live during installaon.
1. Select a covered, dry, vercal wall locaon in a venlated area close to the
baeries. Fix the HRDi using four suitable screws with the wiring block downmost.
Fit the external temperature sensor into its port and place the sensor p in the
vicinity of the baeries. If the sensor is not connected the temperature
compensaon feature is disabled. (Not recommended)
2. Select and prepare cables and connectors rated to connuously carry a minimum
of 10 Amps, no less than 4mm² gauge cable, to link the HRDito each baery. Keep
lengths to a minimum to avoid voltage drop and ensure accurate voltage sensing.
The maximum recommended length is 1.5m.
3. Cauon!
• Set the HRDiCharge / Stop switch to the Stop posion.
• Cover any solar panels and restrain the Windcharger from turning.
• Ensure that any other charge sources to the baery are stopped.
4. Connect the baery link cables to the HRDibaery posions BAT1 and BAT2 if
used but do not connect to the baeries. In service BAT1 must remain connected
to provide the internal power to the HRDi.
5. Connect the 2 Windcharger cables to the WG + & WG - posions and the solar
panel cables to the PV + & PV - posions ensuring correct polarity is observed or
damage will occur. Note : Solar panels must be fied with appropriate blocking
diodes, parallel panels having one each. Keep the solar panels covered and
Windcharger restrained.
6. Connect the other ends of the baery link cables directly onto the baery
terminals + & - of BAT2 first (if used) followed by BAT1, ensuring correct polarity.
The HRDi senses the baery voltage and establishes 12V or 24V operaon.
7. The LCD displays an inialisaon then the connecon status report. Check this
corresponds to your system:
8. Press Connue > (back light buon) or wait 10 seconds for the operang screen
to display.
9. Move the Charge / Stop switch to the Charge posion, uncover any solar panels
and untether the Rutland Windcharger.
The system is now fully operaonal.
User Guidance & Warnings
•Wind & Solar Panel connecons should never be made live or damage will
result. Restrain the turbine or cover the solar panel to prevent power generaon
before connecng to the controller.
•Do not disconnect from the baery unless the Stop switch is acvated.
Reconnect the baery before seng to Charge.
•During installaon or maintenance set the switch to the Stop posion.
•Do not use the Stop switch as a brake. If possible first orient the turbine to a
downwind posion to reduce rotaon and apply the switch to avoid shock loads
that can damage the controller.
•The HRDi must be connected directly onto the baery. On-board baery
management systems must not be allowed to break this connecon.
•SolarPVPanels—do not exceed the 160W maximum rated input. Note : in
ambient temperatures >40°C the solar panel input must be de-rated.
•In high levels of auxiliary charge, eg from an engine, the HRDimay enter
regulang mode and the windcharger will run at a slow speed.
• The logging feature of the HRDirecords up to 9999Ah before automacally
returning to zero if not reset by user in the meanme.
• Latest sengs are retained in the HRDi memory when it is disconnected.
Reconnecon re-acvates the sengs.
• Reprogramming of the Max V/Cell @ 25°C,(bulk,float and regulaon),
temperature compensaon and shutdown may be necessary when using non
lead-acid baeries. Check the baery manufacturer’s advice and contact Marlec
for delas of the PC App and Marlec Controller Interface Lead.
Operang Principles
The HRDiRegulator protects baeries from overcharge. It uses Pulse Width
Modulaon and mul-stage charge technology to maximise the power delivered
to and retained in the baery.
In the bulk/absorpon phaseall the available wind and solar power is used to
charge the baery as quickly as possible. The float phaseensures charge is
maintained whilst minimising gassing thus prolonging baery life. Some
discharging of the baery recommences this cycle.
The temperature compensaon feature automacally adjusts the voltage
regulaon sengs according to deviaons of ambient temperature from 25°C.
The pre-programmed sengs are suitable for lead acid, AGM (absorbed glass
ma) and most Gel type baeries. Default sengs are:
Nominal Baery Voltage @ 25°C 12V 24V
Maximum FloatVoltage @ 25°C 13.8V 27.6V
Maximum Bulk Voltage @ 25°C 14.4V 28.8V
