Weight for complete system: approx. 18 kg (39.6 lbs)

Size: 1100 x 100 mm (43 x 4 in)


  • 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
  • Streamlined body with hard anodized aluminum housing and Delrin covers
  • All screws (A4) are additionally protected against corrosion by Duralac
  • No propeller forces transmitted to the gearbox due to special coupling

Generator Dimensions: Gear drive with shaft and bracket: 1100 x 100 mm (43 x 4 in)


  • Main body manufactured in a solid synthetic material
  • Stove-enameled aluminum propeller blades
  • Blade pitch angle is infinitely adjustable to account for boat type and speed
  • Propeller blades are individually replaceable if needed
  • Blades were designed using CFD software (Computational Fluid Dynamics) to optimize the blade form and twist for superior performance

Propeller diameter: 360 mm (14 3/16 in)

Lifting Mechanism

  • Stainless-steel bracket with adjustable segment, folding-up with a line
  • Folding under speed is no problem because there is a 4 to 1 line reduction ratio
  • The generator is locked into position when deployed
  • Quick connect design for mounting and securing on the mounting bracket

Hydro & Solar Hybrid Charge Controller

  • Rated Power: 1,000W (Best ratio: Hydro Generator 600W, PV cells 400W, max. 60VDC)
  • Applicable batteries: 12V (minimum 200Ah) or 24V (minimum 100Ah), voltage is detected automatically
  • Battery full charge cut: 16V / 32V (adjustable)
  • Battery low voltage disconnect load: 11V / 22V
  • Load current max: 40A (20A at 24V)
  • No load loss: ≤45mA

Working Environment:

  • Operating Temperature: -10 to +50°C (14 to 122°F)
  • Relative Humidity: 0-90%
  • Location: only mount in protected, ventilated area inside the cabin, no exterior installation

Dimensions: 278 x 133x 75 mm (11 x 5.5 x 3 in)

The individual elements can also be ordered as spare parts -> Spare parts for Hydro Charger

ATTENTION! It is possible to operate the Hydro Charger with lithium batteries, but always in consultation and with permission from the battery manufacturer! In this case, an on/off switch relay and diode must always be installed between the Hydro Charger and the Charge Controller, as otherwise, our regulator could suffer damage.

IMPORTANT: Unfortunately, todays there is more and more pollution in the waters, and we would like to point this out to you, we do not offer any warranty or guarantee or assume any liability for damage to the propeller and generator caused by overloading or impact, for example, by objects floating in the water such as lines, fishing nets, plastic debris, containers, seaweed etc.!
