Always enough electricity on board!

Charge your batteries while under sail, just put the generator in the water.




The strengths of the Hydro-Charger

The SWI-TEC Hydro Charger can be lowered into the water while underway and it immediately starts to generate sufficient electricity to keep the batteries fully charged.

The intelligent controller combines both the power generated by the Hydro Charger and a photovoltaic source.

Generates power from 4 knots (depending on boat speed and adjustment of the propeller blade pitch) 50 to 500 Watts depending on speed and battery load.

Easy to use  

The SWI-TEC Hydro Charger, built of solid marine-grade stainless steel, is mounted at a suitable location on the transom, slightly offset from the rudder. The Transom Mounting Fixture incorporates a 4-to-1 block and tackle pulley system allowing the unit to be lowered into- and raised out of the water while underway without any effort.
Once the SWI-TEC Charger Hydro is in the operating position, it snaps in and the strain is taken off the lines. When released by tugging on the separate release line the unit can be pulled up without any difficulty. When leaving the boat unattended the Hydro Charger can easily be removed using the security bolt.

What do the media and users say?

Hi we are now in East London South Africa, we sail around the world with the hydrocharger and from start from Stockholm that will be over 30000 seamile. And we are very happy with the hydrocharger we have so much power so we can sale. This trip had not been so easy without the hydrocharger and we properly have to change batteries, now we always have batteries fully loaded. Tommy


I have installed the Hydrocharger. Works fantastic. At 8+ knots it produces 400 watts and more. I was unable to measure a braking effect, albeit at a slower speed. The installation of two brackets is an ideal solution for boats with an open tailgate or folding mirror. The generator is quite easy to move around, even when driving. However, I did install a stop with a screw with a nut for folding up, since the generator sometimes comes up with momentum and, above all, can be easily fixed in the raised position on the pushpit with the hoisting ropes. The connected solar panel also works perfectly via the controller.
