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 FOXESS 8kW 27.84kWh 1 Phase battery system
A complete single-phase system built around the FOXESS KH8 hybrid inverter and a 27.84 kWh CQ7 high-voltage battery stack — one master unit plus three modules at 6.96 kWh each, all usable.
Stepping up from 5 kW to 8 kW matters where the roof can carry a larger array: three MPPT trackers cover three roof faces and 200% DC oversizing accepts up to 16 kW of panels. The KH series also provides a backup supply, so nominated circuits keep running from the battery when the grid goes down.
Installs as a new system or AC-couples onto existing solar.
Panels, mounting and installation are quoted separately after a site assessment. Indicative values are not a quote.
