Hydro Charger Standard

Always have enough power on board with our Hydro Charger!

Always having full batteries on the boat is a must these days due to the many electronic devices. Use the energy of water and convert it into electricity with our water generator from SWI-TEC. It has been providing sailors around the world with sufficient power for over 10 years.

When sailing, simply lower the generator into the water and electricity is produced and the batteries are charged.

Charging begins at speeds of 3-4 knots (depending on the type of vessel and the basic configuration of the propeller pitch) and varies by speed from 50 to 500 watts, depending on the battery condition.

Key advantages at a glance:

• Very robust stainless-steel construction (V4A)
• Adjustable according to the inclination of the mirror, ensuring the generator always enters the water vertically
• Base plate on the mirror with a massive counter plate (also available separately)
• Easy attachment and detachment with a snap lock and safety feature
• Can be raised and folded down at full speed thanks to a 4-fold rope translation
• Automatically locks into working position, preventing tension on the line during the journey
• Can be immediately released by a sudden pull with a separate line, for hoisting or in case of a collision
• Can be folded vertically upwards when not in use or when the batteries are charged
• Side stops as limits in the water and during hoisting
• Ergonomic design
• Maintenance-free

We also offer a special angle bracket as an accessory, to mount the hydro charger on a bathing platform. And in case of any issues, we have various spare parts available.

Technical data and features

Lifting mechanism:

• Stainless steel bracket with adjustable double segment, foldable upwards using a auxiliary line.
• Easy folding down during the journey, thanks to translation rollers.

• Adjustable pitch according to ship type (speed)
• Replaceable blades (e.g., in case of collision)
• Blades are designed using CFD software (Computational Fluid Dynamics) to optimize the blade form and twist for superior performance

Scope of delivery: Ready to install with regulator, lifting mechanism, generator, propeller, plug, and bracket. Individual elements can also be purchased 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 the permission of the battery manufacturer! In this case, a switching relay must always be installed between the Hydro Charger and the charge controller, otherwise our controller may be damaged!

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 accept 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.!

Please note that we charge a bulky goods surcharge of 29,00 CHF for this product due to the high transport volume!
