Buying Guide

Portable Boat generators are one of the essential boating equipment. It guarantees that all of the boat’s electrical equipment, such as light bulbs, stereo systems, air conditioners, freezers, and other appliances, receives a constant electricity supply. As a result, selecting a marine generator capable of powering all of these electrical components is critical.

Consider these factors before purchasing any portable marine inverter generator for a boat.

Type of Fuel

Consider a generator set that runs on the same fuel as the boat’s inboard engines when making your selection. For example, if a boat’s primary fuel source is gasoline, acquire a gasoline generator for ease. Onboard fishing boats usually have gas inboard engines. Since fishing vessels are less ventilated, diesel generators make more sense than gas generators.

Generator Productivities

Analyzing the power output before making a purchase is vital in evaluating your generator’s capability to power all of your boat’s electrical components. The majority of generators have power outputs ranging from 3.5 kW to 200 kW. As a result, you must determine the overall power requirements of all of your boat’s equipment.

Cooling Capability

The majority of boat generators are water-cooled, and they can employ one of three different cooling methods. Raw water is the cheapest option. The engine is cooled by raw seawater circulated through this system. As a result, they are a poor choice for maritime application due to potential corrosion and contamination issues.

The engine closes the freshwater cooling system, draws cool raw water from outside the hull, and circulates it via coils. Only parts that come into contact with raw water are at risk of excessive corrosion or contamination.

Keel Cooling seals the freshwater system and skips the seawater cooling circuit in favor of a closed-loop water-jacket system. A pump that circulates coolant via a cooling grid on the boat’s bottom. This keel cooler must be kept isolated from the grid of the main engine.

Additional Features

Follow the installation instructions to check that the generator is suitable for your boat. For example, you’ll need to build a water inlet to pull water into the engine to cool it or Install a filter to keep dirt in the water from blocking the generator’s cooling system, and so on.

Some other additional factors to consider are:

  • Load Estimation: Check the installation instructions to make sure the generator will work with your boat. For example, if you want to cool the engine, you’ll need to add a water inlet or filter the water to prevent particles from clogging the generator’s cooling system.
  • Accessibility: All typical maintenance points, such as the dipstick, filters, and oil and water fills, should be located on one side of the generator body for ease of accessibility.
  • Noise enclosures: Although they minimize engine noise, they make maintenance more complex. Look for ones that feature detachable panels, so you don’t have to remove the entire cover to do a little task.
  • Controls: Typically, a separate device is placed on top of the boat generator or incorporated. In comparison to traditional relay controls, digital microprocessor controllers provide substantial diagnostic and monitoring capabilities.
  • Automatic shutoff: If there is low oil pressure, high coolant temperature, lack of coolant flow, or high exhaust temperature in a wet exhaust system, be sure the unit will switch off automatically.

FAQS

1- Can I use a portable generator on a boat?

Yes, a portable generator may supply onboard electrical power for too tiny boats to accommodate a marine Genset. However, portable generators may cause serious safety hazards if utilized wrong. On the other hand, a portable generator is safe to use aboard a boat when appropriately utilized.

2-What size generator do I need to run AC on the boat?

To run AC, you’ll need at least 2000 watts. However, this is entirely related to the power that the AC requires. According to some experts, the best approach to figuring out how big a Gen-set you’ll need is, to sum up, the total wattage of all the AC appliances you’ll be using simultaneously, then divide by 1,000 to get the needed kilowatts. However, you’ll need double that amount, or close to it, to keep your generator from operating at total capacity all of the time.

3- What is the most robust portable generator?

Honda EU2000i is one of the undisputed market leaders as a portable marine inverter generator. The engine has an initial power of 2200W and an operating power of 1800W. Also, the fact that the Honda EU 2200i provides you with more extra watts.
