Why Solar Inverter is So Popular in the Recent Years?

Admittedly, the rapid greenhouse gas emissions and increasingly growing demand for renewable energy are stimulating the business environment of the solar energy industry. Meanwhile, governments’ initiatives to shift to renewable sources of energy to reduce carbon footprint will reshape the market trend tremendously.

Photovoltaic inverter, as one of the most critical components of solar power systems, converts variable direct current (DC) into alternating current (AC) to run residential appliances. The PV inverter market size exceeds USD 19.18 billion in 2021. It is projected to exhibit growth at a CAGR of 5.3% from 2022 to 2028, and reach US$270 Billion By 2028.

So, what exactly is a solar inverter? What convenience can it bring to our lives? How should ordinary people choose the right inverter for themselves? Let’s take a look!

What is a solar inverter?

A PV inverter (PV inverter or solar inverter) converts the variable direct current voltage generated by photovoltaic (PV) solar panels into a utility frequency alternating current (AC), which can be fed back into a commercial transmission system or used off-grid on the grid.

Being an important balance of systems (BOS) in PV array systems, the PV inverter can be used in conjunction with general AC-powered equipment. In addition, it equips special features to match the PV array, such as maximum power point tracking and anti-Islanding Protection.

What does a solar inverter do?

The direct current generated by the photovoltaic module first passes through the DC filter circuit, removes current fluctuations and electromagnetic interference to enter the inverter circuit. Then,
In the inverter circuit, the DC power is converted into AC power, and then the irregular AC power is rectified into sinusoidal AC power. Then, the filtering circuit removes high-frequency interference signals generated during the inverter process, which is integrated into the grid or direct path load.

Types of solar inverters

Centralized inverter

The centralized inverter transforms the aggregated DC power into AC power, making the power relatively large. Therefore, it is widely used in PV power plants.

String inverter

String inverter directly transforms DC power generated by the module into AC power for aggregation. Compared to the centralized inverter, the power of a string inverter is relatively small. With its compact design and the proper size, it realizes easy installation, and has a wide range of applications.


Decentralized inverter

The decentralized inverter realizes string-level MPPT and higher power generation. It boosts DC and AC transmission voltage and reduces losses in the transmission and distribution system. With the advantage of the flexible configuration of capacity and distribution ratio, the decentralized inverter centralized grid connection to provide better grid adaptability, which further reduces operating costs. It will be an ideal power generation solution for power stations in the mountain.

What does a solar inverter do?

太阳能逆变器是做什么的?

光伏组件产生的直流电首先通过直流滤波电路,去除电流波动和电磁干扰,进入逆变器电路。然后。

在逆变电路中,直流电被转换为交流电,然后不规则的交流电被整流为正弦交流电。然后,滤波电路去除逆变器过程中产生的高频干扰信号,并将其并入电网或直接路径负载。

Types of solar inverters

Centralized inverter

集中式逆变器

集中式逆变器将聚集的直流电转换为交流电,使功率相对较大。因此,它在光伏电站中被广泛使用。

String inverter

组串式逆变器

组串式逆变器直接将模块产生的直流电转化为交流电进行汇总。与集中式逆变器相比,组串式逆变器的功率相对较小。由于其设计紧凑,尺寸合适,实现了安装方便,应用范围广泛。


Decentralized inverter

分散式逆变器

分散式逆变器实现了组串级MPPT和更高的发电量。它能提高直流和交流传输电压,减少输配电系统的损失。分散式逆变器具有容量和分配比例灵活配置的优势,集中式并网提供更好的电网适应性,进一步降低运营成本。它将成为山区电站理想的解决方案。
