ESY Sunhome Battery

Walk into most homes with a solar battery and you will find a wall of boxes – an inverter here, a battery unit there, monitoring hardware somewhere else, all wired together and hoping they talk to each other. The ESY SunHome was designed to make that approach obsolete.

One Enclosure, Everything Inside: Inverter, battery, monitoring, and safety – all integrated into a single premium unit. Cleaner installation, simpler maintenance, and a system that is engineered to work as one from the factory floor up.

Grows With Your Household: Start with what you need today. Single-phase models begin at 5.12 kWh and expand to 30.72 kWh by simply adding modules to the stack – no new hardware, no rewiring. Three-phase models push that to approximately 90 kWh through parallel connection. Whether your family grows, you add an EV, or you just want more independence from the grid, the system grows with you.

Built for Australian Conditions – IP66 Rated: Victorian summers, coastal humidity, dusty conditions – the ESY SunHome carries an IP66 rating meaning it is fully sealed against dust and high-pressure water. This is not a box you need to worry about.

Power Stays On When the Grid Goes Off: The ESY SunHome switches to backup power in under 20 milliseconds. That is faster than a blink. Your fridge keeps running, your router stays connected, and your household carries on without anyone noticing the grid went down.

Safety Built Into Every Layer: LFP (Lithium Iron Phosphate) chemistry is the most thermally stable battery chemistry available – and ESY goes further with five layers of protection: intelligent BMS control, temperature monitoring, circuit fuses, fire safety devices, and anti-corrosion engineering. This is a system you can install in your home and genuinely forget about.
