How Does Inverter Work in Power Station?
As we can see, there are a lot of power stations appearing in the market, like power banks. However, a power station has more functions than a power bank does. Its power and capacity are much larger than a power bank. Besides that, power stations have some hard drives, such as a battery management system (BMS), charging protocol chip (ex. Q.C. PD, Thunder, etc), and inverter. So today hereby the introduction of inverters that merged with power stations.
What Is An Inverter?
We can think of an inverter as a conversion device that adopts current between direct current (DC) and alternating current (AC) to the required power for a certain device, interchangeably. The current in the battery is basically DC, and the current of household power utility is used by AC. You can see the 110V/220V AC outlet that is mounted on the wall, which is the power source from AC. In general, inverters have been widely used in electrical appliances, and it is a necessary part of unit. Not only in power stations but air conditioners, personal computers (PC), fridges, electrical fans, even an 5W LED light bulb, they all have inverters in different sizes, on printed circuit boards (PCB).
Features
To be more specific, or hardcore, we can say, inverters consist of an inverter bridge, control logic, and filter circuit. The common components are rectifying diodes and silicon-controlled rectifiers (SCR). There are two kinds of the inverter, one is pure sine wave inverter, and the other one is a correction wave (square wave or modified sine wave, quasi sine wave, sine wave simulation) inverter. The output waveform of correction wave inverters from a positive to a negative maximum value has a maximum time interval and its effect is improved some, but the quasi-sinusoidal waveform has still belonged to the category of square wave that it wave is composed of a line. The continuity is not sufficient, sometimes it will shorten the life span of connected devices. The modified sine wave inverter generally uses a non-isolated coupling circuit, while the pure sine wave inverter uses an isolated coupling circuit design and its price is also very different. It will quit the market, eventually. Compared with a pure sine wave, it is characterized by high conversion efficiency and fast start-up speed, coupled with its own short circuit and over-heat, protection function. It has a good dissipation performance because its exterior is aluminum made. In summary, the stability of load operation is also a very strong, relatively stable function, which is more skewed by the market.
How to Calculate the Inverter Convert Ratio?
The inverter consumes some electrical power from itself when working. Therefore, its input power is greater than its output power. The inverter efficiency is the ratio of the output power to the input power. This means the inverter efficiency is the ratio of the output power to the input power. For example, when an inverter has 100W DC input and converts 90W AC as output, the convert rate of the inverter is 90%. The higher the convert inverter does have, the better quality it will be.
Back to the topic of energy storage, some products do not have an inverter, they need to be purchased separately. Energizer now has portable power station products. They are an energy storage system. With a high conversion rate of pure sine wave inverter, it allows you to charge multiple device to your phones, laptop, utilities, etc. Energizer portable power stations also contain BMS, MPPT for solar input, and LiFePO4 battery. Compared with industrial standards, Energizer portable power stations can save your budget on energy, the battery management system can enhance its battery lifespan, and its charging cycle is up to 2000+ to 80% at minimum. Energizer all-in-one solutions of solar generator, power more safely, power more efficiently.
