Hydro-Charger Swi-tec Standard

Always enough electricity on board with the SWI-TEC Hydro Charger.

Under sail, you can recharge the batteries and use all the on-board equipment without fear by immersing the generator in the water!

We also combine hydroelectric and photovoltaic energy with our intelligent charge controller.

• For 12/24 Volt systems
• Programmable maximum voltage level, e.g. 16/32 Volts
• Maximum charging current 40 A/12 Volt
• Electronic charge regulator with automatic limitation programmable according to battery capacity
• Programmable charging with integrated digital display
• Connection of solar panels up to 200 Watt / 16 Ampere
• 20A/12 Volt Power Socket for 220 Volt / 50Hz Inverter for Charging Cell Phones, PC, TV, etc.

Generator:

• Silent operation
• Adjustment of the angle according to the inclination of the stern so as to always have the generator in the water in a vertical position
• It can be immersed in water and withdrawn during navigation thanks to the demultiplied system
• Stays locked in vertical working position without strain on the hoist system
• It exits the water quickly in case of need using a second line
• It comes out of the water in its vertical position when the batteries are charged or at mooring
• Side stops prevent the generator from touching the transom
• Ergonomic shape
• Low revs thanks to an excellent transmission ratio
• No propeller vibration thanks to the integrated clutch system
• Optimal geometries (fluid mechanics)
• Waterproof thanks to two o-rings on both sides
• Easily disassembled
• Anodized aluminum body and special plastic cover
• A4 screws with anti-corrosion treatment
• No interference of the propeller on the transmission, as they are separated by a clutch
• Virtually imperceptible when immersed in water
• Start charging at 3-4 knots of speed, however depending on the pre-set pitch of the propeller blades

Propeller:

• Main parts made of special plastic material
  
• Propeller pitch preset according to the type of boat and its speed
• Propeller blades individually interchangeable, for example in the event of a crash
• MFN (Fluid Mechanics) blade geometry calculated for our hydro-charger with optimal shape and curves

Electronic charge controller:

• It can be adjusted up to 16/32 Volts, ideal for compensating voltage losses
• It uses MPPT technology - Maximum Power Point
• Integrated propeller rotation release: the propeller rotates freely without friction when the optimum battery voltage is reached
• Digital display for function control integrated into the appliance
• Prepared for connection of solar panels or wind generator. The predisposition provides for direct use: everything contributes to the recharging of the batteries with detachment when the optimal voltage of the same is reached.

IMPORTANT: Our Hydro-Charger regulator can only be used for solar panels up to max. 60V DC! There are new solar panels on the market that have more than 60vdc. These must not be connected to our device because it can be irreparably damaged, causing the warranty to expire.

Fixed transom mount:

• Very robust construction in stainless steel (Aisi 316)
• Transom fixing bracket with very robust internal counterplate
• Fixing system on the mirror that allows easy and safe locking/unlocking of the Hydrogenerator

To be installed inside the vessel

Attention! It is possible to operate the Hydro Charger with lithium batteries, but always after consultation and with the approval 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, nowadays there is more and more pollution in the waters.
Therefore, we do not offer any warranty or insurance or accept liability for damage to the propeller and generator caused by impact with floating objects in the water such as ropes, fishing nets, plastic parts, containers, algae, etc.

We charge a bulky freight surcharge for this product. The total cost is shown at checkout.
