What is a boat inverter?
An inverter is a device that converts direct current into alternating current. Marine inverters are actually not a type of inverter, but a type of inverter usage. Users can carry the inverter on the ship to convert the DC power on the ship, such as the DC power of the battery, into the ship’s DC power. AC power is required to meet the power supply needs of various electrical equipment and charging equipment on board.

Normally, most of the power on a ship comes from DC power provided by the ship’s diesel generator or solar panels. However, the electrical equipment we use every day can only run on AC power.

Users need to select the inverter output voltage and frequency suitable for their own country and region before they can use the inverter normally on the ship.

Classification of marine inverters (high-frequency inverters)
According to the different output waveforms, marine inverters are generally divided into two types:

Pure Sine Wave Inverter
A pure sine wave inverter produces an output waveform that is consistent and of high quality, very close to the sinusoidal waveform of the main grid. Pure sine wave inverters are capable of driving all devices, especially those that are sensitive to power quality, such as medical equipment, audio equipment, microwave ovens, etc. The disadvantage of a pure sine wave inverter is that the price is higher than that of an ordinary inverter.

Modified sine wave inverter (or approximate sine wave inverter)
The voltage transformation is not continuously smooth. Its advantages are its simple structure and low price, and it can meet the needs of non-sensitive electrical equipment such as electric heaters, electric fans, and lights. However, for those that require precision power supply, such as computers and certain types of TV or audio equipment, using a modified wave inverter to drive may produce noise or even damage the equipment.

How does a marine inverter work?
In the first step, the switching circuit inside the inverter converts DC power into high-frequency AC power. This technology is called “Pulse Width Modulation” (PWM) technology, which can change the direction and intensity of current by controlling the switching speed and duration of the switching circuit, thereby generating alternating current.

In the second step, the inverter uses a device called a “filter” to convert the high-frequency, sawtooth-shaped alternating current into the sine wave-shaped alternating current used in people’s daily lives. The main function of the filter is to remove high-frequency noise from AC power and retain only the frequencies we need.

The necessity of using inverters on ships
1.electricity supply
Ships need to power various equipment and systems, such as lighting, communication equipment, navigation equipment, refrigeration equipment, etc. The inverter can convert DC power into AC power to meet the power needs of this equipment.

2.Charging equipment
Power tools, cell phones, computers, and other devices can be charged on board. Inverters convert onboard power to the appropriate voltage and current for efficient charging.

3. Emergency backup power supply
On ships, inverters and batteries can be used as backup power systems to provide emergency power when the main power supply fails or is interrupted. This keeps you safe while sailing at sea.

4. yacht or boat solar power generation system
The inverter on the ship can be connected to the solar panel to realize the solar power generation system to charge the battery. Provide a continuous power supply for navigation.

5. Electronic device compatibility
The inverter can provide stable AC power to ensure the normal operation of electronic equipment on board. This is an effective protection for computers, televisions, stereos and other equipment that require high current value and quality.

Advantages of marine inverter
It enables a variety of electrical equipment to achieve standard power output on board.
It saves electricity, improves energy efficiency, and extends battery life.
It has high conversion efficiency, convenient use, and simple operation.
It has high safety and can effectively avoid ship accidents caused by electrical problems.

Technical characteristics of marine inverter
stabilization technology
The safety and stability of marine inverters are top priorities, and users do not want to experience frequent jitters or failures during use. Therefore, in the design and manufacturing process of inverters, Junchipower uses high-quality components, strict production processes, scientific quality assurance systems, and other means to ensure product stability.

Temperature control technology
Because of the working principle and technology of the inverter, it will inevitably generate heat. Therefore, Junchipower adopts some effective heat dissipation and cooling control technologies to ensure the normal operation of the inverter.

Includes a high-efficiency radiator and fan cooling system and an overheating protection system.

Circuit protection technology
Marine inverters are usually affected by some external interference, such as too high or too low voltage, too high current, overload, and other factors, which can lead to inverter failure and damage. Therefore, Junchipower is equipped with six protection systems for the inverter. When encountering under-voltage, over-voltage, over-current, etc., it can automatically take measures to protect the inverter.

conclusion
Marine inverters are an important part of ship power systems and have a wide range of applications. This article introduces the principles, classification, and application technology of marine inverters, hoping to provide reference and help for everyone. As an important piece of equipment on the ship, it needs stable power output.

In order to achieve stability and reliability of power output, marine inverters require suction power. When purchasing a marine inverter, you can choose a product that suits you based on your actual needs and the model of your ship.
