The Rutland HRSi regulator controls the level of voltage and as such, the amount of charge being delivered to your batteries to prevent any damage to them. The HRSi uses PWM (pulse width modulation) technology to create a multi-stage charging output, similar to a modern battery charger.

The intelligent microcontroller inside ensures the maximum amount of energy is transferred to the batteries until they have reached peak voltage, at which point the unit forces the windcharger and any solar input to 'idle' bringing the output down to a 'float' voltage to prevent battery damage. This also extends the life of the wind charger. If the batteries begin discharging again, the controller restores full output from the windcharger and any solar to reinstate maximum charging again.

The HRSi has an input for the wind generator, one input for solar panels and a single output for one battery bank. It is designed to operate with the Rutland 504 or 914i windcharger and up to 160W of solar panels. The unit is equipped with a turbine/solar shutdown switch and for ease of installation, it auto detects the system voltage (12V or 24V).

Why choose Rutland?

Low wind speed start up

When the wind is light, many wind turbines remain stationary, producing no power. Rutland wind generators feature low friction high output generators with modern aerodynamic fan blade design, so they have unrivaled low wind speed start up. The result is that they start making useful power long before many competitors will even begin to rotate.


Marlec Engineering have been making wind generators in their UK factory since 1979. With many years of product feedback from tens of thousands of units shipped worldwide - you will enjoy the reliability this experience brings.

Quiet operation

How many times have you heard someone curse a whistling or howling wind turbine? Don't be put off having a wind generator because you think it may be anti-social; simply choose a Rutland and relax; you've got the quiet one! Rutland are world renowned for their near silent operation; just walk around a marina and listen for yourself.


Using the free power of wind to charge your batteries, you can reduce your fuel consumption by not having to run your engine or generator so often.
