Hydro Charger Standard

Technical Data

Mechanism to lift

Stainless steel bracket with adjustable segment, folding-up with a line. Folding under speed is no problem, because there is a 4:1 line reduction ratio. Generator is locked into position when deployed. Quick fastener device for mounting on transom bracket.


Generator part: Gear drive with shaft, propeller and programmable converter charger with digital display and 4 m 3-core cable

Performance: Generates power from 4 knots (depending on boat speed and propeller blade pitch)

Output: 50 to 600 Watts depending on speed and battery load

Generator Dims.: Gear drive with shaft and bracket: 1100 x 100 mm, propeller diameter 360 mm


Rated Power: 1.000W (Best ratio: Hydro Generator 600W, PV cells 400W)

Applicable batteries: 12V from 200Ah up to —-, 24V from 100Ah up to — (voltage detected automatically)

Battery full charge cut: 16V /32V (adjustable)

Battery low voltage disconnect load: 11V / 22V

Load on voltage: 12.44V (default adjustable)

Load current max: 40A (20A at 24V)

No load loss: ≤45mA

Dimensions: 278 x 133x 75 mm

Weight: 1,6 kg

Working environment: Working temperature: -10-50°C Relative humidity: 0-90% (no exterior  installation, only inside the cabin)

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 ropes, fishing nets, plastic parts, containers, seaweed etc.!


  • 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

The Hydro Charger will always be in a vertical position in the water an therefore can achieve an optimal performance.

The holes are identical to the normal transom bracket and can be retrofitted with the normal bracket.

The swing resistance is adjustable using the self-locking nut. Thereby you achieve a slowly drop of the Hydro Charger.

This bracket is specifically for the sideway fitting of the transom.

For the use with lithium-ion battery it is absolutely obliged, the installation of a breaker in the yellow AC cable, between generator and controller, which is commanded from the BMS (Battery Management System) of the battery. This installation has to be approved from the battery producer. Swi-Tec overtakes no responsibility for this installation.
