At Seek Solar, we believe your home energy system should do more than generate power - it should help you take control of it.
That's why we're proud to offer the ESY Sunhome range, an intelligent all-in-one battery storage solution designed to help Australian households reduce grid reliance, lower electricity bills, and prepare for the future of home energy.
Whether you're adding battery storage to an existing solar system or planning a complete energy upgrade, ESY Sunhome combines advanced technology, premium safety features, and seamless performance in one sleek package.
By storing excess solar energy produced during the day, you can power your home after sunset, protect yourself against rising energy costs, and enjoy greater energy independence.
Unlike conventional battery setups that require separate inverters, monitoring systems, and complex wiring, ESY Sunhome integrates everything into a single, streamlined solution.
For larger homes and households with higher energy demands, the latest three-phase Sunhome models - including the HM10-H, HM15-H, and HM20-H - deliver scalable storage of up to approximately 90kWh, making them ideal for EV charging, electrification projects, and whole-home backup.
