ESY. Energy, Sun, You. In 2004, an engineer devoted himself entirely to one thing: Battery Management Systems. His company designed BMS solutions for Huawei, Dell, and Toshiba — for 14 years. The deeper his technology grew, the more an idea took shape: to go further. In 2018, ESYsunhome was founded. E is for Energy — Starting from energy itself, making every kilowatt-hour count. S is for Sun — Harnessing the power of sunlight, so every ray can be stored and used. Y is for You — 20 years of BMS expertise, from industrial solutions to home applications, from serving enterprise clients to serving every “You.” Top 5 in the Australian residential storage market, TÜV-certified, operating in over 50 markets, with 5 local teams worldwide, and a 100,000 m² smart factory in Shenshan. The brain keeps growing. Wherever the sun reaches, ESY will follow. And that is where the next 20 years begin. ESY. Energy, Sun, You.
