1.What is an inverter?

As a new energy company that has served 5,000+ customers, Yuli Energy will help you understand inverters. First of all, we need to know what an inverter is. The process of converting DC power into AC power is called reversal, and the equipment that completes the inverter process is called an inverter.

2.The 3 main types of inverters.

  Inverters can be categorized according to waveform, frequency, number of output phases and whether they are connected to the grid or not. Today, we mainly differentiate inverters by whether they are connected to the grid or not. They can be categorized into: grid-connected inverters, off-grid inverters and hybrid inverters.

3、Characteristics and applications of 3 types of inverters.

Regardless of the type of inverter, they are not good or bad. In different scenarios and environments, the type of inverter needed is different.

• Grid-connected inverters.

Definition:

The grid-connected inverter converts the DC power generated by distributed power sources such as solar panels and wind turbines into AC power, boosts the voltage through a transformer, and then selects the maximum power point through a low-voltage DC switch (MPPT). Finally, it does not do any The battery storage is output directly to an inverter connected to the grid. Grid-connected inverters are mainly used to integrate distributed power sources into large power grids to achieve interconnection and complementation of multiple energy sources. Of course, it will also have certain thresholds and must comply with relevant regulations and policies of the local power grid.

（2）Off-grid inverter.

Definition:

Off-grid inverter means a system that is disconnected from the public power grid. The DC power generated by the solar panels is first stored in the battery, and then the battery is transported to the off-grid inverter for inversion. The resulting AC power can be directly supplied to the off-grid inverter. Load use can also be returned to battery storage. It is more suitable for remote areas without power network coverage, such as deserts, plateaus, and deep forests, and can provide power needs anytime and anywhere.

（3）Hybrid inverter.

Definition:

Hybrid inverters convert DC power into AC power or vice versa to meet the needs of different power systems. During peak shaving and valley filling of the power system, energy storage inverters can store excess power in the power grid for use during peak demand periods, thereby improving the stability and reliability of the power system. In terms of emergency backup power, energy storage inverters can respond quickly and release stored power to meet emergency needs during power grid outages.

• So after the above explanation, I believe everyone already knows how to distinguish various inverters. So how do we choose?

• Policy influence. Some governments provide subsidies for residents to sell electricity. Therefore, most citizens will buy hybrid inverters at this time. Mainly Australia, the United Kingdom and other regions
• Lack of power resources and high demand. The supply of power resources in some countries is very unstable, resulting in citizens’ power resources being in short supply and the government not subsidizing them. Most citizens will choose an off-grid system to better meet their needs.
• Price. Compared with hybrid inverters, off-grid inverter systems are simpler. Off-grid inverters are therefore cheaper.
• Power requirements. Industrial electricity sales need to be connected to the grid, with greater power and better safety.
