How To Choose The Right Boat Generator

How To Choose The Right Boat Generator

Posted by Admin on 1st Dec 2020

People mainly go for boat generators to help with the AC aspect during navigation. However, in cold climates, there will always be a need for 120 volts. If you plan on spending some of your days on the water, you'll need a generator for your boat. Why is one going to be important? If you're on vacation, you'll want to focus more on the excitement of your sailing expedition rather than other things. A generator will keep your batteries running while you have fun. Are you residing in Wellington, FL, and looking for a power generation company? You can consider Ace Power Products, LLC for your generator and phasor marine generator parts.

How Many Kilowatts is Needed For Your Boat Generators?

Most technicians have given us a clue on how to do this. You add the total wattage of all the components you'll be making use of while the generator is on and divide it by 1000; that will give you the number of kilowatts you require. However, you don't go with the exact number of kilowatts you get from the calculation; you should go with twice the figure you get as a safety precaution. Using the actual figure might result in overload and damages that will require the need for phasor marine generator parts to get your generator back and running again. Overloading has a way of stressing the engine so bad that it can cause damages that will shorten the generator's lifespan. It is ideal for your generator to run between a range of 35 to 80 percent of the total load. At least a 5-kilowatt generator should be enough.

Investing In Inverters

Generator installments are often a complex and very costly procedure to carry out. If you plan on installing a generator, it could cost you thousands of dollars, but you'll also need an inverter in addition to your generator. Inverters, on the other hand, are far less expensive; a typical inverter could cost you up to 3000 USD, and the installation process is relatively easy to handle. You should get one for your boat, even if you don't have a generator, because having an inverter can help you run components with small wattage in the absence of your generator. They are best utilized with house batteries. It would be best if you've got a generator.


When you see XX amps at WOT on some engines, that's how the alternator output is displayed. It is the optimum output the alternator can deliver; however, it's not every time the electric system uses the maximum amp. Once the amp the electric system requires is less, the alternator will produce less. The rating of most alternators come with an 80-degree alternator cold and 6000 alternator RPM. The RPM of the alternator differs entirely from that of the engine because there is a ratio between RPMs of alternators and those of the engine due to similar diameters of the alternator pulley and the drive. To calculate your alternator size, add all the DC loads in your boat together, ensure the maximum capacity of the alternator is 20% or more; maybe 25% should be ideal.
