Hydro Charger

Charge your batteries under sail by lowering the generator in the water.

Combined water power and solar power with an intelligent Converter Charger.

  • Solid stainless steel construction ( Aisi 316 )
  • Quick fastener device for mounting on transom bracket
  • Foldable at full speed through 4x reduction ratio line
  • Generator locks into working position when deployed in the water (easy release by lightly pulling on the red line)
  • Can be stored in fully inverted position (for ex. in harbour)
  • Lateral stoppers to avoid generator hitting on transom
  • 20 A/12 V socket for watermaker, inverter 220 V / 50Hz, (115V / 60Hz) for charging cellular phones, TV, PC etc.
  • Programmable converter charger with digital display
  • Max. current programmable depending on battery capacity

Included in delivery


  • Smooth running through custom-designed planetary gear
  • Low ratio prevents high motor speeds
  • Optimized efficiency through custom-designed transmission
  • Double seals (2 O-rings each)
  • Multiple-bearing propeller shaft
  • Easy to remove and disassemble
  • Hard anodized aluminium housing and special synthetic cover.
  • Streamlined anodized aluminium body
  • All screws (A4) are additionally protected against corrosion by Duralac
  • No propeller forces transmitted to the gearbox due to special coupling
  • Almost inaudible in the water
  • Charging from 4 knots upwards (depending on the pitch setting angle setting of the propeller blades)



  • Main body manufactured in a solid synthetic material
  • Stove enamelled aluminium propeller blades.
  • Blade angle is infinitely adjustable depending on type of the boat (speed)
  • Propeller blades are replaceable (i.e. after collision)
  • Blades were designed using CFD software (Computational Fluid Dynamics) to optimize the blade form and twist for superior performance



  • Up to 16/32 volt adjustable, perfect to compensate for voltage loss
  • With built-in free wheel (propeller turns freely when max. retained battery voltage is reached)
  • Additional connection for solar panels or wind generator
  • Additional connection for direct output, which will be automatically shut down when sufficient battery voltage is obtained
  • NEW: integrated, digital display
  • NEW: additional switch for free wheel
  • NEW: additional alarm when battery is completely charged
  • NEW: higher output

Our Hydro Charger control unit can be used only for solar panels up to max. 60vdc! There are new solar panels on the market that have more than 60vdc. These must not be connected to our controller because it can be destroyed, and no warranty will be refunded.
