Solar generators

A boat generator works by providing a steady supply of power during extended time at sea. Many generators are designed specifically for marine applications and have features such as corrosion-resistant casings and components, water-resistant switches, and fuel tanks that are sealed to prevent leaks.

When considering a solar generator for a boat, it is important to ensure that it has enough power output to meet your needs. For example, if you plan on powering big items like air conditioners, you will need a generator that can handle larger loads. Additionally, maintenance and safety precautions should be considered to ensure the generator lasts longer and operates efficiently.

Choosing the right generator

When choosing a generator for your boat, there are a few things to consider. Firstly, you need to decide whether you want a solar-powered or portable generator. Solar generators are environmentally friendly and can power lights, electronics and appliances. They use photovoltaic panels to convert sunlight into electricity, which is then stored in batteries for use when the sun is not shining. Some larger boats may also have an inverter to convert the stored DC power into AC power for use with standard household appliances.

Portable generators, on the other hand, can be a good option if you need to power larger items such as air conditioners. They are also useful if you only need to power small to mid-size items like phones, tablets, and laptops, as well as mini-fridges, coffee makers, rice cookers, and microwave ovens.

Another important consideration is the power output of the generator. You need to make sure that the generator you choose has enough power to handle the loads you plan to put on it. If you are powering large items, you will need a higher-powered generator.

Finally, it is important to consider the features of the generator that make it suitable for marine applications. Look for generators with corrosion-resistant casings and components, water-resistant switches, and fuel tanks that are sealed to prevent leaks.

By considering your power needs and the features of the generator, you can choose the right generator for your boat.

Installing a generator

First, it's important to choose the right generator for your boat. Consider a generator that burns the same fuel as your vessel's powerplants to minimise the hazard of mixing fuels. This will also simplify the installation process, as you won't need to install additional fill and vent lines. If your boat originally offered a generator as optional equipment, check with the manufacturer to see if pre-tapped mounting plates were laminated into the stringers, as this can provide an ideal mounting point.

Next, you'll need to ensure you have all the necessary components for the installation. In addition to the generator itself, you'll need items like a sound enclosure, water lift muffler, exhaust hoses, a fuel filter, and wiring. The exact components will depend on your specific generator and boat setup.

Now, let's move on to the installation process. Start by creating a solid, level mounting surface for the generator. Generators are weighty, so secure mounting is crucial. Through-bolts or hefty brackets are recommended for a secure installation. Ensure you have enough room for cables and hoses, and consider access to the area, as you'll need to be able to get the generator through the hatch.

Once the generator is mounted, you can begin the wiring process. This can be tricky, so it's important to follow the manufacturer's specifications for both the boat and the generator. You'll need to connect cables for an externally mounted battery for starting the generator, the AC output, and you may also wire in a remote-control panel above decks.

Finally, don't forget to install a cooling water feed and an exhaust run. Intake lines should have a sea strainer between the seacock and the generator, and it's recommended to avoid scoop-style through-hulls, as these can force water into the generator when it's not in operation.

By following these steps and consulting with professionals as needed, you can successfully install a generator on your boat, ensuring a steady supply of power during extended time at sea.

Using a generator safely

Generators can be a great source of power for boats, providing electricity for various electrical systems, including lights, electronics, and appliances. When using a generator, it is important to follow safety precautions to ensure a safe and efficient experience.

Firstly, it is crucial to choose a generator that is specifically designed for marine applications. These generators have features such as corrosion-resistant casings and components, water-resistant switches, and sealed fuel tanks to prevent leaks. Ensure that the generator has enough power output to handle your needs. If you plan on powering large items like air conditioners or refrigerators, opt for a higher-powered generator.

Another safety consideration is the proper installation of the generator. Installing a generator on a boat can be challenging, and it is important to follow the manufacturer's instructions carefully. Ensure that the generator is securely mounted and that all connections are properly made.

Regular maintenance is also key to safe generator use. Follow the manufacturer's recommendations for maintenance and servicing to ensure optimal performance and longevity. This includes tasks such as checking fluid levels, cleaning or replacing filters, and inspecting for any signs of wear or damage.

Additionally, it is important to be mindful of carbon monoxide poisoning when using a generator. Ensure that the generator is adequately ventilated and never run it in an enclosed space without proper ventilation. Keep a safe distance from the generator when it is in operation, and be aware of any potential symptoms of carbon monoxide poisoning, such as headaches, dizziness, or nausea.

Finally, always follow basic safety precautions when using a generator. This includes properly grounding the generator, using appropriate fuel types, and avoiding overloading the generator. Be mindful of your surroundings, and keep children and pets away from the generator at all times. By following these safety guidelines, you can confidently use a generator to power your boat's electrical needs.
