Microinverter upgrades will eliminate risks of electric shock fire and rescue market share gradually increases


Microinverters can maximize the overall output power at the component level and can completely eliminate the risks of electric shock, fire and rescue caused by high-voltage arcing. It is expected that as the proportion of distributed devices increases, the penetration rate will explode.

1)Basic knowledge of microinversion

1. What is microinversion used for?

Improve power generation efficiency and power generation: The micro inverter directly connects the inverter to the photovoltaic components, and each component is connected in parallel to achieve maximum power point tracking (MPPT) at the component level. By optimizing the output power of each module, the Maximize overall power output.

Solve potential safety hazards: The DC voltage of centralized or string inverter systems can reach 600-1500V, while micro-inverters are connected to the power grid in parallel, and the DC voltage generally does not exceed 80V, completely eliminating the risk caused by high-voltage arcing. Risk of electric shock, fire and rescue.

Micro single-watt prices are higher and are mainly used for distributed photovoltaics with higher safety requirements.

2. Microinverters have a long life, usually 25 years. Using parallel connection to connect to the power grid, it has higher independence, smaller mass and volume. Even if a single inverter fails, the photovoltaic system can continue to generate electricity. It is mainly used for distributed photovoltaics with high safety requirements.

3. North America and Europe are the two most important markets for microinverters.

From 2016 to 2020, the combined shipment volume of microinverters in the North American and European markets accounted for more than 80%. The shipment volume of microinverters in Latin America increased rapidly, accounting for 8% in 2020. Global inverter shipments in 2020 were 185GW, a year-on-year increase of 43%, and the inverter market size has reached US$7.19 billion. Microinverter shipments were 2.28GW, accounting for 1.2%, and the market size has reached US$741 million, accounting for 10.3%.

2) Driven by both distributed share and penetration rate, the micro-inverse market is expected to explode

1. Distributed proportion: The global distributed proportion is expected to increase to 50%.

As the advantages of distributed photovoltaic power generation gradually come into play, distributed markets such as China, Brazil, and India will grow rapidly, and the European and American distributed markets will maintain steady growth. China's distributed economy has benefited from "county-wide promotion" and "rural revitalization." The European energy crisis has superimposed the Russia-Ukraine war, and various countries have promulgated new energy substitution policies. In the future, there will be a market pattern in which centralized and distributed markets develop together.

2. Micro-reverse permeability rate: Safety standards have improved, and component-level products are expected to experience explosive growth.

Countries around the world have increased safety requirements, which will greatly promote the development of domestic photovoltaic module-level products. After the results of the domestic "Notice on Strengthening the Safety of Distributed Photovoltaic Power Generation (Draft for Comments)" are officially released, component-level products will usher in explosive growth. The microinverter market size is expected to reach 32.5 billion yuan in 2025, with a CAGR of 47.22% from 2020 to 2025, and shipments will reach 38GW. As technology matures, costs fall, and safety regulations become increasingly stringent, the microinverter market size will further increase. #Photovoltaic inverter#

The European micro-reverse market is mature, and the distributed share and micro-reverse penetration rate are both higher than the global average. Coupled with the heightened awareness of the energy crisis in Europe due to war disturbances, the scale of the micro-reverse market is expected to increase significantly. China has the largest amount of newly installed distributed power, and as domestic safety regulations further improve, it will become the largest potential market for microinverters.
