2 Power Conversion System Market Growth Drivers and Restraints
Increased penetration of renewable energy and demand for grid stability
Countries around the world are accelerating their transition to renewable energy, and the volatility of distributed energy sources such as solar and wind energy has led to a surge in demand for energy storage systems in the power grid. As the core equipment for energy storage, the power conversion system can achieve two-way conversion of electric energy and balance grid load fluctuations.
For example, China’s “14th Five-Year Plan” emphasizes the proportion of energy storage, and the US IRA Act promotes the implementation of energy storage projects through tax credits, directly driving PCS demand. In 2022, the proportion of renewable energy installed capacity in the Asia-Pacific region reached 35%, driving the region’s PCS market size to account for 51.17% of the world.
Policy support and improvement of market mechanisms
Countries have encouraged the development of energy storage through policies such as subsidies and capacity markets. For example, the EU’s “Sustainable Energy Development Plan” requires energy storage capacity to reach 400 GWh by 2030, and Germany has promoted the popularization of household energy storage through the “Energiewende” plan; China’s “Guiding Opinions on Accelerating the Development of New Energy Storage” clearly states that the energy storage installed capacity target for 2025 is 30 GW. In addition, power market reforms (such as the US FERC Order 841 allowing energy storage to participate in ancillary services) have increased the commercial value of PCS.
User-side energy storage demand has exploded
Industrial and commercial users are actively deploying energy storage systems to reduce the cost of peak-valley electricity price differences. In 2022, the commercial sector accounted for 21.60% of PCS market revenue, and the residential sector accounted for 22.45%, becoming the main growth pole. Household energy storage systems (such as SMA’s Sunny Tripower) combined with photovoltaic self-consumption have been rapidly popularized in Europe, Japan and other places due to high electricity prices and energy autonomy needs.
Technological progress and cost reduction
High voltage (such as 1500V system) improves efficiency and reduces costs. Sungrow’s 1500V PCS system has increased efficiency by 0.3% and reduced costs by 5%. The localization and large-scale production of IGBT modules have driven down prices. The global average price of PCS has dropped from 113 USD/KW to 103 USD/KW from 2020 to 2022, stimulating market penetration.
Global energy transformation and regional market expansion
Asia-Pacific (especially China and India) has become the largest market (accounting for 51.17% in 2022) due to rapid industrialization and growing electricity demand; the Middle East and Africa have benefited from the surge in solar energy projects, and large-scale energy storage tenders in Saudi Arabia, the United Arab Emirates and other countries have driven regional growth; the Latin American market (such as Mexico and Brazil) has gradually released its potential due to new infrastructure policies.
Upstream supply chain bottleneck
IGBT modules rely on European and American manufacturers such as Infineon and ON Semiconductor. The localization rate in the Asia-Pacific region is less than 30%. The global IGBT shortage in 2022 will extend the PCS delivery cycle to 40 weeks. Fluctuations in the prices of battery raw materials such as lithium and cobalt (such as the price of lithium carbonate, which rose by 500% in 2022) push up the cost of energy storage systems and squeeze PCS profit margins.
Technical standards and certification barriers
Standards in different regions vary significantly (such as UL 1741 in North America and VDE-AR-N 4105 in Europe), and companies need to invest high certification costs. Emerging markets (such as Africa) lack unified standards, resulting in poor system compatibility and hindering the layout of multinational companies.
Single business model and long investment return cycle
At present, energy storage mainly relies on policy subsidies, and market-oriented profit models (such as auxiliary services and capacity markets) are not yet mature in most countries. The investment payback period of large-scale grid-side projects exceeds 10 years, which restricts private capital investment. The initial cost of household energy storage is high (such as a 5kW system is about US$15,000), and the penetration rate is limited by the user’s ability to pay.
Geopolitics and trade frictions
The Sino-US trade war has caused Chinese companies such as Huawei and Sungrow to face tariff barriers when entering the North American market; Europe’s protection policies for local manufacturing (such as the Net Zero Industrial Act) require localization rates, increasing the compliance costs of Chinese companies. While the Russian-Ukrainian conflict has pushed up European energy prices, it has also led to a strengthening of the regionalization trend of the supply chain and increased global supply chain risks.
Technology maturity and safety hazards
The risk of thermal runaway of lithium batteries has caused concerns about the safety of PCS. In 2022, the number of fire accidents in global energy storage power stations increased by 40% compared with 2020. Although alternative technologies such as flow batteries are highly safe, they have low energy density and slow commercialization, which restricts the diversification of PCS technology routes.
3 Technological Innovations in the Power Conversion System Market
High voltage and high efficiency
1500V system has become the mainstream. ABB, Sungrow and other companies have launched high-voltage PCS suitable for large-scale energy storage, with system efficiency exceeding 98.8%. Huawei’s “extremely simple architecture” solution reduces switching devices through cascade technology, improving reliability while reducing losses.
Intelligence and digitalization
PCS with integrated AI algorithms can optimize battery life (such as Soaring’s intelligent thermal management system extends battery cycle life by 20%), and supports virtual synchronous machine (VSG) technology to improve grid support capabilities. Delta Electronics’ PCS achieves remote monitoring and fault prediction through the cloud platform, reducing operation and maintenance costs by 30%.
Modular and integrated design
The household field tends to be an all-in-one design (such as SMA Sunny Tripower Smart Energy), integrating inverters, BMS and EMS; the grid side adopts a containerized modular solution (such as Dynapower’s CPS-3000), which supports rapid deployment and capacity expansion, and shortens installation time by 50%.
Multi-energy integration and compatibility with new technologies
The combination of hydrogen energy storage and PCS has become a hot topic. The fuel cell inverter developed by Nidec can be adapted to hydrogen energy storage systems; PCS dedicated to flow batteries (such as TBEA’s all-vanadium flow inverter) has a long lifespan and its penetration rate in grid-level energy storage has increased to 8%.
Horizontal expansion of leading companies
ABB strengthened its software capabilities by acquiring Germany’s Ventyx, integrating its EMS and PCS products to form an integrated “hardware + software” solution. In 2022, the proportion of software business revenue increased to 15%. Sungrow acquired some assets of Rongxin Shares to expand high-voltage inverter technology and improve the grid-side product matrix.
Cross-border companies enter the market
CATL invested in Flow Batteries, a US energy storage integrator, to lay out the flow battery + PCS ecosystem; Tesla acquired Maxwell to enhance supercapacitor technology and applied it to the PCS of its Megapack energy storage system to reduce its dependence on lithium batteries.
Regional market integration
European manufacturers accelerate localized M&A: Fimer acquires Italy’s 3SUN’s photovoltaic inverter business, integrating PCS and photovoltaic products; Enel Green Power acquires Spain’s X-Elio’s energy storage project portfolio, supporting its own PCS products and consolidating its market position in southern Europe.
