Hydro Marine Charging & Generators

With our trusted team of marine energy specialists, Australian Marine Sales is your go-to source for cutting-edge, sustainable power solutions for your vessel. We supply hydro marine charging systems Australia-wide and work with recommended installers to ensure seamless integration. Our hydro charging solutions harness the movement of water to generate clean, reliable energy—perfect for extending your journeys while reducing fuel dependence. 

What is Hydro Charging?

Hydro charging is a marine energy solution that converts the kinetic energy of water movement into electricity. Using a hydrogenerator mounted at the stern of a vessel, the system harnesses the natural force of flowing water as the boat moves, spinning a turbine to generate clean, renewable energy.

How It Works:

  1. The hydrogenerator is deployed into the water while the vessel is in motion.
  2. As water flows through the turbine, it generates mechanical energy.
  3. This energy is converted into electrical power, which is then stored in the boat’s battery system.

Smart charging technology ensures optimal voltage regulation, preventing overcharging and maximizing efficiency.

Comparison with Other Renewable Marine Energy Sources

By integrating hydro charging into your boat’s energy system, you gain a silent, eco-friendly, and cost-effective power source, reducing reliance on fuel and maximizing your time on the water.

Wind Turbines

Depend on consistent wind conditions, which can be unpredictable. 

Hydro Charging

Works continuously as long as the boat is moving, providing a reliable and consistent source of power. 

Key Features & Benefits

Continuous Renewable Energy

AMS Hydro Marine Charging systems provide a steady and reliable power source while your boat is in motion. Unlike traditional energy solutions that rely on fuel or inconsistent weather conditions, hydro charging works day and night as long as there is water movement. This ensures that your batteries remain charged throughout your journey, allowing you to power essential systems without interruption. 

Efficient & Silent Operation

Unlike noisy fuel generators that disrupt the tranquility of the open water, hydro charging operates silently and efficiently. Enjoy the peace of your marine adventures without the constant hum of an engine running in the background. The energy generated is clean, consistent, and requires minimal maintenance, making it an ideal solution for those who appreciate quiet cruising. 

Compact & Lightweight Design

Designed for ease of installation and storage, AMS Hydro Marine Charging systems feature a streamlined and lightweight construction. They can be deployed and retracted with minimal effort, making them a practical addition to any vessel. When not in use, they can be easily stowed away without taking up valuable space on board. 

Eco-Friendly Solution

Reduce your fuel consumption and carbon footprint with a clean, renewable energy source. Hydro charging eliminates the need for fuel-powered generators, which contribute to greenhouse gas emissions and pollution. By integrating this technology into your boat, you’re making a sustainable choice for the environment while also saving on fuel costs.

How Hydro Charging Works

Hydro charging is a revolutionary energy solution that harnesses the movement of water to generate electricity, providing a continuous and sustainable power supply for marine vessels.

Step-by-Step Breakdown of the Hydro Charging Process:

  1. Deployment: The hydro generator is mounted on the stern of the vessel and lowered into the water.
  2. Water Flow Activation: As the boat moves, water flows through the generator’s turbine, causing it to spin.
  3. Energy Conversion: The spinning turbine converts kinetic energy into mechanical energy.
  4. Electricity Generation: A built-in alternator transforms the mechanical energy into electrical power.
  5. Battery Charging: The generated electricity is directed to the boat’s battery system, ensuring a steady and regulated power supply.
  6. Smart Energy Regulation: The system automatically adjusts voltage output to optimize charging efficiency and prevent battery overcharging.
  7. Energy Utilization: The stored energy can then be used to power onboard electronics, navigation systems, refrigeration, and other essential equipment.

Energy Conversion and Storage Efficiency:

  • High Conversion Efficiency: Hydro charging systems maximize energy extraction from water movement, ensuring optimal power generation with minimal losses.
  • Smart Regulation: The system adjusts to different speeds and water conditions to maintain efficient and stable charging.
  • Battery Integration: Works with 12V, 24V, or higher-capacity battery banks to store energy for later use, ensuring uninterrupted power even when the vessel is stationary.

Different Types of Hydro Charging Setups and Configurations:

  • Fixed Stern-Mounted Generators: Installed permanently at the stern for consistent power generation.
  • Retractable Hydro Generators: Designed for easy deployment and removal when not in use.
  • Towable Generators: A trailing system that floats behind the boat, commonly used for long-distance sailing.
  • Hybrid Systems: Integrated with solar or wind power setups to provide a complete renewable energy solution for marine vessels.

Why Choose Hydro Charging for Your Boat?

Cost Savings Over Time Compared to Fuel Generators

Fuel-powered generators require constant refueling, maintenance, and repairs, leading to high operational costs. Hydro charging, on the other hand, utilizes the free and natural energy of water movement, reducing the need for fuel consumption and lowering overall energy expenses. Over time, this translates into significant cost savings for boat owners.

Reliability for Long-Distance and Off-Grid Sailing

For long-haul sailors and those venturing into remote waters, energy reliability is crucial. Hydro charging ensures that your power supply remains stable, no matter where your journey takes you. Unlike solar panels that rely on sunlight or wind turbines that depend on wind conditions, hydro generators work continuously as long as the boat is moving, providing an uninterrupted energy source.

Environmental Benefits and Contribution to Sustainable Boating

Hydro charging is a zero-emission energy solution, helping boat owners reduce their carbon footprint. By eliminating the need for fuel-burning generators, hydro charging plays a role in preserving marine ecosystems and promoting sustainable boating practices. Choosing a clean energy source ensures that your adventures at sea have minimal environmental impact.
