APsystems Achieves Top Rank as Most Profitable Inverter Manufacturer by Sinovoltaics

APsystems Becomes the Most Profitable Inverter Manufacturer

On September 1, 2025, APsystems, a prominent player in the power electronics industry focusing on Module Level Power Electronics (MLPE), was officially named the most profitable inverter manufacturer globally by Sinovoltaics in their 2025 rankings. This prestigious recognition spotlights APsystems' robust financial status and unwavering commitment to innovative solar technology.

The evaluation carried out by Sinovoltaics employs the Altman Z-score, a reliable predictive model that assesses the financial health of companies and their likelihood of facing financial distress. Not only did APsystems secure the highest score in this sector, but it also demonstrated consistent financial strength over the analysis period from 2022 to 2025. Olivier Jacques, the global president of APsystems, remarked, “Achieving the number one ranking is not just an honor but a validation of our long-term vision and commitment to excellence.” APsystems has built its foundation on innovation, strong profitability, and market-relevant ecosystems over the past 15 years in the solar industry.

Dr. Zhi-min Ling, co-founder and president of APsystems, emphasized the importance of profitability in the solar energy sector. “Installers, EPCs, and financial entities need assurance that the technology they deploy today will continue to provide support in the future,” he stated. This ranking from Sinovoltaics reinforces that APsystems is dedicated to uphold this promise year after year, thereby maintaining trust among clients, partners, and financial sponsors.

Limitations of Manufacturing

The Sinovoltaics report is recognized as the most comprehensive independent financial analysis of inverter manufacturers in the industry. Utilizing the Altman Z-score, which analyzes factors such as current assets, retained earnings, EBIT (earnings before interest and taxes), market value, and sales, it scrutinizes each manufacturer's financial stability and their potential 2 to 10-year survival probabilities. Manufacturers are then categorized into three zones: Safe, Gray, and Danger. With the highest Altman Z-score, APsystems is positioned securely in the Safe Zone, differentiating itself from dozens of competitors worldwide.

A History of Innovation and Solid Growth

APsystems began its journey in Silicon Valley in 2010 and has since expanded its footprint to over 150 countries. By the end of 2024, the company had shipped more than 6 GW of MLPE products and installed over 590,000 microinverter systems worldwide. Despite the competitive landscape, APsystems has consistently achieved profitability and maintained a substantial warranty reserve, with millions of microinverter systems operating reliably over a decade after installation.

From its successful dual-module microinverter DS3 series to the advanced three-phase QT2 commercial platform, and the plug-and-play EZ1 units, APsystems continues to push the technological boundaries of solar energy, earning the trust of installers, distributors, homeowners, and financial entities across the globe. With the integration of cutting-edge solar technologies and energy storage, powered by AI-driven innovations, the company is reimagining the future of energy solutions for residential, commercial, and DIY applications.
