Key Features
Inverter and battery combined in a single floor-standing unit. 20% less floor space and 20% faster installation compared to separate component systems, with Plug & Play commissioning.
Start with as little as 9.6 kWh per stack and expand up to 102.4 kWh across four battery stacks — without replacing the inverter or redesigning the system.
Provides three-phase backup power across your entire home during grid outages, switching in under 10 ms. Compatible with three-phase appliances and EV chargers.
Lithium iron phosphate prismatic cells with a settable 100% depth of discharge. No capacity held in reserve — every kilowatt-hour you install is available to use.
Backed by Sieyuan Electric — a Bloomberg NEF Tier 1 energy storage manufacturer with 33 years of experience and US$5 billion in annual turnover, ensuring long-term support availability.
All-in-One System Three Phase HV (10–20) kW
A high-capacity integrated three-phase system for larger Australian homes, farms, and light commercial properties. Three independent MPPT inputs handle up to 40,000 Wp of solar, while parallel master-slave stacking enables large-scale energy storage and output. Whole-home backup switchover in under 4 ms — the fastest in this class.

Key Features
Three independent MPPT inputs handle up to 40,000 Wp of solar panels — ideal for large roof areas or properties with multiple panel orientations maximising generation at all times of day.
Your home transfers to battery power in under 4 milliseconds during a grid outage — before most sensitive appliances register any interruption.
Multiple units can be combined in a master-slave configuration, scaling both AC output and storage capacity to match the demands of larger properties without a system redesign.
Built-in AC charging capability supports EV charging directly from stored solar energy, eliminating the need for a separate EV charger unit.
Capable of exporting up to 43 kW back to the grid or powering high-demand applications, with a maximum phase output current of up to 30.3 A.
Why it's our top pick
The all-in-one advantage for Australian homes.
Swatten's integrated approach removes the complexity of separate inverter and battery components — faster installation, greater reliability, and a single manufacturer warranty covering the entire system.
Not a performance warranty — Swatten replaces the entire machine. Full unit replacement in the event of a fault, covering both inverter and battery as one integrated system for 10 years.
Backed by Sieyuan Electric — a Bloomberg NEF Tier 1 energy storage manufacturer with 33 years of experience and US$5 billion in annual turnover, ensuring long-term parts and support availability.
LiFePO4 prismatic cells with a settable 100% depth of discharge. Every kilowatt-hour of installed capacity is available to use — no reserve held back by the system.
Both systems support expansion to 102.4 kWh of total storage across multiple battery stacks. Start at the right size for today and grow capacity as your needs change.
