Hydro Charger Standard

Reliable electricity on board with a Hydrogenerator

How do I get enough power on board? This is arguably the most crucial question while sailing. We have the answer -> Our SWI-TEC Hydro Charger.

Electronic devices are becoming increasingly popular at sea, whether it's refrigerators, mobile phones, laptops, or various other devices. Our hydrogenerator harnesses the energy of the water and converts it into electricity.

The generator is simply lowered into the water while sailing, and it starts producing power and charging the batteries. In addition, we combine hydropower and photovoltaics with our intelligent control unit. Charging starts from 3-4 knots (depending on the type of ship and the basic setting of the propeller pitch) at speeds ranging from 50 to 500 watts (also dependent on battery status).

All the advantages of our Hydrogenerator:

• 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

Art. No. 7148 Hydro Charger Standard with 24 Volt system with standard bracket

We also offer a special angle bracket as an accessory, to mount the hydro generator on a bathing platform.

Technical data and features of the Hydrogenerator

Lifting mechanism:

• Stainless steel bracket with adjustable double segment, foldable upwards using an auxiliary line.
• Easy folding down during the journey, thanks to translation rollers.
• Locking mechanism during the journey. Quick attachment to the mirror with a snap lock.

Generator:

• Smooth operation due to a special planetary gear
• Low generator speeds due to a small translation
• Optimized efficiency through special translation
• No vibrations on the propeller due to a built-in clutch, making it nearly silent in the water
• Hard-anodized aluminium housing and cover made of special plastic
• Streamlined anodized aluminium profile
• All screws made of stainless steel (A4)

Technical details:

• Sealed on both sides with 2 O-rings each
• Multiple-bearing propeller shaft

• 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, hydro generator, propeller, plug, and bracket. Individual elements can also be purchased as spare parts -> Spare parts for Hydro Charger.

⚠️ Important Notes

It is possible to operate the Hydro Generator with lithium batteries, but always in consultation and with the permission of the battery manufacturer! A switching relay must always be installed between the generator and the charge controller, otherwise, the controller may be damaged.

Unfortunately, due to increasing water pollution, we do not offer warranty or liability for damage caused by debris, ropes, fishing nets, plastic parts, seaweed, etc.

Note: A bulky goods surcharge applies due to the transport volume.
