Ten Step Quick Start Guide
The sequence of connection is critical to the voltage set up of the HRSi. Follow these
instructions carefully to ensure no connections are live. See Fig 2 for guidance.
instructions carefully to ensure no connections are live. See Fig 2 for guidance.
1. Select a covered dry wall location in a ventilated area close to the batteries.
2.
Select cables and connectors that will continuously carry a minimum of 10 Amps. No less than
4.0 mm² gauge cable should be used to provide the link from the HRSi to the battery.
3.
Cut the minimum cable necessary to link the HRSi to the battery, thus avoiding voltage drop and
ensuring accurate voltage sensing. The maximum recommended length is 1.5m.
ensuring accurate voltage sensing. The maximum recommended length is 1.5m.
4.
Caution. Before any connections to the HRSi are made, cover any solar panels and restrain the
Windcharger from turning. Ensure that any other charge sources to the battery are stopped.
5.
Set the HRSi Charge / Stop switch to the Stop position.
6.
Connect the 2 Windcharger cables to the Windcharger positions ( WG + & WG - ) and the solar
panel cables to the solar panel positions ( PV + & PV - ) ensuring correct polarity is observed.
Note : Solar panels must be fitted with appropriate blocking diodes , parallel panels having one
each. Keep the solar panels covered and Windcharger tied.

7.
Connect the battery link cables to the HRSi battery positions, (BAT+ & BAT- ).
8.
Connect the other ends of the battery link cables to the battery terminals, ( + & - ) ensuring
correct polarity. This senses the battery voltage and establishes 12V or 24V operation.

9.
Uncover any solar panels and untether the Rutland Windcharger.
10.
Move the Charge / Stop switch to the Charge position and the system is operational.
Operating Principles
The HRSi Regulator protects batteries from overcharge. It uses pulse width modulation and
multi-stage charge technology to maximise the power delivered to and retained in the battery. In the
bulk/absorption phase all the available wind and solar power is used to charge the battery as quickly
as possible. The float phase ensures charge is maintained whilst minimising gassing thus prolonging
battery life. Any discharging of the battery recommences this cycle.
The temperature compensation feature automatically adjusts the voltage regulation settings according
to deviations of ambient temperature from 25°C. The pre-programmed settings are suitable for lead
acid, AGM (absorbed glass matt) and most Gel type batteries. Other settings are available, contact
Marlec to discuss your requirements. Default settings are:
