Significance Of Marine Generator Onboard
Boats consist of appliances that consume A/C power such as refrigerators, navigation devices as well as water heating systems among others. Supplying sufficient power to these appliances can be a challenge when you are out on the water.
Keeping the main engines running is a good option of powering all the appliances. However, this option is not a perfect one since it leads to noise, fumes and increased fuel consumption. The choice of keeping the main engine running can affect your peace of mind at sea. A marine generator is ideal since it provides a quieter and energy efficient solution while you are out on the water.
Some boats have batteries that store power generated by the marine generators. However, you can use an inverter on the ship to convert the energy from DC to AC should the needs arise.
Watt (W) is the unit that represents power, and it is a product of 1 volt and 1 Amp (Watt=1 volt x1 Amp). One thousand watts make up a total of 1kW and many generators operate at 230 volts
