Who this suits
Largest in range; large home or small commercial.
Before you choose on size
Federal battery certificates are tiered — weighted toward the first 14 kWh of usable capacity, tapering from 14 to 28 kWh, and small above that. A larger battery does not attract a proportionally larger discount. Choose capacity on your evening and overnight usage and whether you want extended backup, not on the rebate.

What is in the GoodWe 15kW 48kWh 3 Phase battery system


The largest GoodWe system in our range: the 15 kW three-phase ESA all-in-one with six high-voltage battery modules — 48 kWh of usable storage.
Maximum generation capacity and maximum storage in one product family. At 200% DC oversizing the inverter accepts up to 30 kW of panels, and 48 kWh of storage carries a high-consumption property through extended outages. This is the configuration for large rural properties and small commercial sites where continuity of supply is the point.
The ESA integrates the inverter, meter, backup changeover switch and battery base into one unit and is grid forming, establishing its own supply during an outage.
Because 15 kW is above the usual Victorian residential range, network approval and export limits need confirming for your address. A six-module stack weighs around 475 kg, so wall structure and clearances are assessed on site. Panels, mounting and installation are quoted separately. Indicative values are not a quote.
