Important Facts to Know Before Buying a Marine Generator
In theory and application, a marine generator isn’t much different than any other generator. A marine generator is typically powered by diesel or gasoline to produce energy that is converted to electrical energy inside the generator. This electricity can then be used to power various appliances and equipment inside a boat. You’ll find a marine generator in just about every larger boat out there, from fishing boats to yachts.
However, it’s important to note that there is a huge difference between a normal generator and a marine generator. For this reason, a standard generator should never be used on-board a ship. Many generators are far less efficient in a moist environment and it could cause them to stop working altogether. When water splashes on the boat, your average generator would be out of commission.
Marine generators, on the other hand, are designed to survive the harsh and wet environment of the boat. This requires different design techniques on the outside and alternative components on the inside. Many marine generators may utilize hydraulic pump systems, use more durable material, include H Class insulation, and have other features that make them more efficient for life on a boat.
Why You Need a Marine Generator
You may be wondering why you need a marine generator. After all, you have a battery in your boat and you could always use an inverter to create Alternating Current from the battery. This is perfectly fine as long as the power consumed remains under 3,500 Watts.
Unfortunately, this is rarely the case, as a single toaster consumes more than half of that limit. If you’re running any serious appliances, such as an air conditioner, a refrigerator, or any combination of smaller appliances, then you’re going to need more energy than your batter can supply.
A marine generator is perfect for the job. If you choose a generator of appropriate size, then it can easily power all of your appliances without putting any additional strain on the boat’s battery. Simply put, marine generators are a must have item for any serious boater.
As with any type of generator, there are always certain safety factors you must keep in mind when choosing a marine generator. These safety factors could be for your good or for the environment, but they always help. For example, it’s common knowledge that any generator produces some pollution as a by-product. This is already bad for the environment, but it gets worse. If your boat is stationary, then this carbon monoxide pollution can actually build up inside the boat. The gas is highly poisonous and can have some serious adverse health effects if allowed to build up in the cabin or other enclosed area.
For this reason, you should keep emissions in mind when you are shopping for a generator. There are some generators built with sensors that cut off the generator when carbon monoxide levels climb too high. You should also consider installing similar sensors throughout the boat to ensure safety at all times.
Importance of Appropriate Voltage Regulation
When choosing a new marine generator, you should pay close attention to the voltage regulation. These numbers always coincide with the AC frequency, which is either 50Hz or 60Hz. The former is for European standards while the latter is used in America.
A 50Hz electrical appliance also runs with a 220 V regulator while for American appliances, the values are 120/240 V. For standard appliances 120 Volts is used, while 240 is used for motors, such as air conditioners, dryers, and equipment.
It’s important that the generator’s voltage is listed clearly.
The frequency of a generator is determined based on its motor speed. The best choices are either 1,500 or 1,800 RPM. The first is for 50Hz and the second for 60Hz. There are faster and slower options, but none are as effective as these standards.
Use this information to choose a marine generator that is modern, safe, effective, and reliable. You don’t want to invest in a generator that will break next month, so put time into finding the best brands and manufacturers in your area or on the Internet.
