What 麦田能源有限公司 does

Fox ESS Co., Ltd. (麦田能源有限公司) is a privately held Chinese renewable energy company founded in 2019 and headquartered in Wenzhou, China. The company designs and manufactures an integrated smart renewable energy ecosystem comprising solar inverters (microinverters, string, and hybrid), lithium iron phosphate (LFP) battery storage systems, EV chargers, and heat pumps, all connected through its FoxCloud 2.0 software platform. Its technology stack includes proprietary SiC (silicon carbide) power electronics (first-mover adoption of Infineon's SMD full-SiC solutions in the PQ3-Ultra), high-efficiency power conversion (up to 98.78% PV grid-tied efficiency), modular battery designs scalable from 5.18 kWh to 241.05 kWh, and AI-driven energy optimization.

The company sells primarily through a multi-channel model combining direct enterprise sales, a network of 200+ distributors across 70+ countries, a formal installer program (launched November 2025), and VPP partnerships (Amber Electric, Origin Loop in Australia). Customers span residential homeowners (the primary segment), commercial and industrial users (via G-MAX / G-MAX Plus AC-coupled storage), EV owners, and heat pump buyers. Pricing is quote-based with no public list pricing, and revenue is overwhelmingly hardware-driven with accompanying warranty and service. Strategic partners include Infineon (SiC semiconductors), NGEN (AI-driven EMS for C&I), GPC Europe, VDH Power, Solar Juice, and OSW.

S&P Global Energy ranked Fox ESS No. 1 globally in residential energy storage by MWh shipments in 2025, with the company also achieving No. 1 in Germany, the UK, and Australia, Top 3 in seven countries, BloombergNEF Tier 1 status, 97% System Performance Index (HTW Berlin, No. 1 in the 10kW category), and Forbes Global Unicorn List / Hurun Global Unicorn Index inclusion. The company has 5,700+ employees, six R&D centers, two Wenzhou factories totaling 390,000+ m², and submitted an IPO application in 2025 following pre-IPO financing that valued the company at over RMB 10 billion.
