Key Features
Supports 4 independent PV strings, equivalent to approximately 200 m² of rooftop solar. Ideal for large or complex roof designs where panels face multiple orientations.
Powers every appliance in your home simultaneously from solar, including EV chargers, heat pumps, ducted air conditioning, and large kitchen appliances.
Automatically schedules energy purchases when grid electricity rates are lowest, maximising financial savings whether on a flat or time-of-use electricity plan.
Fully integrates with EcoFlow's home energy ecosystem, including EV charging, heat pump control, and smart home appliance management, all from one app.
Modular LFP battery packs stack to deliver up to 61.2 kWh of total capacity, covering multi-day energy independence for even the largest Australian homes.
Is premium right for you?
Built for those who want it all.
A premium high-capacity system is the right choice when maximum self-sufficiency, EV charging, or extended backup duration is the priority.
Households consuming 30+ kWh per day need a larger battery bank to achieve meaningful overnight coverage and genuine grid independence.
Charge your electric vehicle entirely from solar energy stored during the day. A premium system stores enough to fuel both your home and your car.
Systems at the maximum 50 kWh usable capacity are eligible for up to $6,238 from the federal Cheaper Home Batteries Program — the highest rebate available under the program.
With up to 45.9 kWh (PowerOcean) or 61.2 kWh (PowerOcean Plus) of storage and continued solar charging during daylight hours, a premium system keeps your home powered through extended grid outages.
