ESY Sunhome is one of the core battery and hybrid inverter brands we install across the Northern Beaches, North Shore and Eastern Suburbs — a modular LiFePO4 storage system, CEC-approved and AS 4777.2 grid-connection certified, backed by a local Sydney sales and after-sales service team.
ESY Sunhome's HM-series batteries stack in 5kWh–6kWh modules, so a system can be sized precisely to a household's usage now and expanded later without replacing the inverter.
ESY Sunhome's parent company has been manufacturing lithium batteries since 2004 and became a leader in Battery Management System (BMS) technology in 2011. The ESY Sunhome brand was established in 2021 to focus specifically on home battery energy storage, expanding into the Australian market in 2022.
Single-phase all-in-one system. A 6000W hybrid inverter paired with modular LiFePO4 batteries.
ESY Sunhome's newest single-phase system, with a higher-output 10kW hybrid inverter for homes with heavier loads (EV charging, heat pumps, larger air conditioning).
For larger three-phase homes and bigger loads, scaling well beyond a typical single-phase system.
All ESY Sunhome systems use LiFePO4 batteries rated to 6,000+ cycles, carry an IP66 ingress protection rating, and are on the CEC approved list. We don't put prices online. Every job is quoted in person, on site.
