What Hoymiles does

Hoymiles Power Electronics Inc. (禾迈) is a Hangzhou-headquartered, Shanghai-listed (SSE: 688032) new-energy manufacturer founded in 2012/2014 that designs and produces module-level power electronics, residential and C&I battery storage systems, and utility-scale containerized energy storage across DIY, residential, commercial, and utility customer segments. Its product platform is anchored by the HMS, HMT, MIT, HiFlow, and MIS-W Pro microinverter families (300 W to 5 kW outputs) and has expanded into integrated storage with the HiBattery 4020 hybrid and AC-coupled home batteries, the HiOne all-in-one residential BESS, the HoyUltra 2 and HoyCore liquid-cooling C&I systems, and the HoyPrime, HOYAC, and HOYDC utility-scale containers. The company's proprietary S-Miles Cloud platform and S-Miles Home app provide monitoring, while the AI-EMS embedded in flagship products and the S-Miles AI Assistant for customer support reflect a deliberate software layer built on 13 years of operational data.

Hoymiles generates revenue primarily through hardware sales — microinverters, batteries, power conversion systems, string inverters, and containerized storage — distributed via an extensive channel-partner and certified installer network across 190+ countries, with regional subsidiaries in the EU, Australia, the United States, and India, plus four manufacturing bases including a Mexico facility operational since 2024. Recurring service and warranty-extension programs (Extend Warranty, certified installer tracks, third-party warranty inclusion via Solar Insure) supplement the hardware-led model. Go-to-market combines channel-partner distribution, flagship-event-driven demand generation (SNEC, Intersolar Europe, RE+, REI Expo India, StorageNext), direct-to-consumer sales for DIY and balcony homeowners via the website and mobile apps, and OEM-embedded large-volume deals such as the 360 MW KOSOL Energie microinverter contract for India's PM Suryaghar Yojana. Pricing is quote-based, disclosed volume tiers for project deals indicate multi-year contracts, and the company holds certifications including BEE (India), EcoVadis Gold (top 4% globally), EUPD Innovation Award, and the 2025 Hangzhou Municipal Green and Low-Carbon Factory Model Enterprise designation.
