Traditional generators are typically powered by fossil fuels such as diesel or gasoline. These fuels provide power to the engine connected to the alternator to generate electricity. To produce the standard current used in most households, the generator needs to operate at a constant speed of about 3000 rpm. If there are fluctuations in the engine’s speed, the power output will also fluctuate. Therefore, when the generator is operating, there are slight variations in engine speed, leading to variations in power waves.
This is why the output of generator inverters is not a pure sine wave.
·What is an inverter?
An inverter refers to a device that converts direct current (DC) from a battery pack to alternating current (AC), which is required by most devices. Simply put, an inverter is an electronic device that transforms low voltage (12V, 24V, or 48V) DC to 220V AC. Typically in our lives, we convert 220 volts AC to DC for use, but an inverter does the opposite, hence the name.
Why pure sine wave inverter？
There are mainly three types of waveforms for inverters, namely modified sine wave inverters, pure sine wave inverters, and square wave inverters.
Pure Sine Wave Inverter: A pure sine wave is a smooth, continuous, and periodic waveform, with its voltage varying over time according to a sine function. The pure sine wave is a powerful waveform that can keep devices operating. Pure sine wave inverters can output high-quality alternating current and can drive various types of loads, causing essentially no damage to the loads or the inverters themselves.
Modified Sine Wave Inverter: The output waveform of a modified sine wave is not as smooth and continuous as a sine wave; it has a time interval from the positive maximum to the negative maximum. Compared to a pure sine wave, a modified sine wave has a lower cost and a simpler structure. However, the AC waveform of the modified sine wave may have some degree of distortion, which may affect some sensitive electronic devices. Therefore, for applications with high waveform requirements, pure sine waves are usually a better choice.
A square wave inverter outputs a kind of poor-quality square wave alternating current, where the positive and negative peak values occur almost simultaneously, causing damage to the load and the inverter itself. The rising and falling edges of the square wave are very steep, almost vertical. Square waves are widely used in timers, switch power supplies, and other fields. However, for devices that require continuous, smooth alternating current, the square wave is not suitable. In such cases, a pure sine wave inverter would be more appropriate.z
How to connect pure sine wave inverter rv？
You can insert a portable inverter device into the cigarette lighter of the RV. This method usually only has a power of 200-400 watts and provides a 120V AC power socket, allowing you to charge your laptop.
2. Install the inverter directly to the battery pack of the camper. If we spend more time in the wild than in the campground, then we will rely more on the battery pack. Therefore, we use efficient DC alternative devices as much as possible, eliminating the need for extensive AC circuits, and we can install the inverter directly to the battery pack of the camper。
