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 9.99kW 48kWh 3 Phase battery system
The three-phase GoodWe ESA all-in-one with six high-voltage battery modules — 48 kWh of usable storage, the largest battery in our range.
This is a system for properties that must stay running through multi-day outages, sites at the end of a weak line, and homes where nearly all energy use has been electrified across three phases.
The ESA integrates the inverter, meter, backup changeover switch and battery base into one wall-mounted unit, and it is grid forming — during an outage it establishes and holds its own supply rather than disconnecting with the network.
Four MPPT trackers and 200% DC oversizing accept up to 19.98 kW of panels. A six-module stack weighs around 475 kg, so wall structure, position and clearances are assessed on site. Panels, mounting and installation are quoted separately. Indicative values are not a quote.
