What does a marine inverter do?
A marine inverter takes DC power from the boat’s battery pack and converts it to AC, so you can use “household” items on the boat, and also use the AC charger to charge a dead phone or laptop without having to connect with shore power or generator installation.

How do i choose an marine inverter?
Marine inverters are divided into pure sine wave inverters and modified wave inverters according to different output waveforms. The modified wave inverter produces a waveform similar to going up and down stairs to mimic the waves of pure alternating current and can run most household gadgets, but may experience issues such as “electronic noise” that may cause some projects to not run at full capacity. What’s more, sensitive electronics require pure sine waves to function properly, and you can cause permanent damage if you try to run them with a modified wave.

The pure wave produced by a pure sine wave inverter is similar to a rolling wave on an ocean: it rises and falls in a smooth line like an AC power source. While inverters that use this type of sine wave are generally more expensive, they are much better at handling sensitive electronics and ensuring your items operate at their peak performance levels.

If you want more stable AC power, or you are using precision electronics, you should choose a pure sine wave inverter, it will give you more protection.
 
Why does my boat need an inverter?
The 120volt AC power on a ship typically comes from three sources: shore power, generators or inverters. If you don’t want to be tied to the dock all the time, you’ll have a choice between generators and inverters to meet your electrical needs. Generators generate large amounts of continuous power and are ideal for running air conditioners, large freezers, and other high-load, long-duration applications. They can also charge the batteries on board via a marine AC battery charger, the downside is that the generator requires fuel, an exhaust system, and maintenance of the generator engine and generator itself. Also, their AC output is often not as stable as the one in your home because they experience periods of sluggish operation, spikes and surges. For example, impurities in the fuel supply can cause abnormal operation, resulting in power spikes or surges. This can cause serious damage to complex users such as computers or printers. Although modern technology has improved generators, they do take up space, vibrate and may not be very quiet.

Inverters have many advantages when AC power needs are small or you don’t want the generator running, they are an economical, maintenance-free and relatively compact power converter. The inverter is small in size, takes up little space, and makes little noise when working. The pure sine wave inverter simulates the voltage change of the mains through a complex circuit, and its output power quality is the same or even better than the mains. It is suitable for operating all types of loads, including resistive, capacitive and inductive loads. Good quality pure sine wave inverter is more suitable for radio, communication equipment, medical equipment and precision instruments.

When your boat needs access to extra power, installing an marine power inverter is a good option for both practicality and cost. Our customer hopes that we can customize the power solution for his boat. His boat is 13 meters long and uses 10 12V batteries in series, the input voltage is 120V, and the range is 100V-150V. We customized inverters suitable for them: two inverters are installed in this boat, 110Vdc/230Vac BP series 5000W inverter and 110Vdc/230Vac 6000W inverter. 110Vdc/230Vac 5000W inverter for a 3HP air conditioner, 110Vdc/230Vac 6000W inverter for a 3HP air conditioner and a 1500W kettle.
