ESY SUNHOME started out as a lithium battery business, powered by cutting-edge battery protection systems and a proficient Research & Development team. The founder, Mr. Lee, recognized the shortage of energy storage choices available to households worldwide and was enthusiastic about combining photovoltaic energy storage solutions with lithium batteries. With this vision in mind, the team embarked on the development and testing of PV home energy storage products, forming an efficient, highly qualified team of Research & Development, manufacturing, and quality control professionals with distinguished backgrounds in various fields of technology. After years of intensive effort, the team successfully developed and tested PV home energy storage products, resulting in the official launch of the HM6 series storage system products on January 14th, 2023. ESY SUNHOME now has branches in Sydney, Australia and Munich, Germany, with a long-term objective of becoming a global brand.
