An all-in-one battery with its own solar hybrid inverter, expandable to 54 kWh with Expansion Units. *Power is configurable; unlimited cycles for self-consumption use under Tesla's warranty.
Tesla Powerwall 3 supplied and installed by our SAA accredited installers across Queensland.
Powerwall 3 is an all-in-one home battery: the 13.5 kWh lithium iron phosphate (LFP) battery, a solar hybrid inverter with three MPPTs, and the power electronics all live in one wall- or floor-mounted unit. Because the inverter is built in, most homes don't need a separate solar inverter at all. It can take up to 20 kW of DC solar input.
How it works, simply: during the day, surplus solar charges the battery instead of being exported for a few cents. In the evening the battery powers your home before you draw from the grid. LFP (lithium iron phosphate) chemistry is known for thermal stability and long cycle life.
It suits homes installing new solar and a battery together, owners who want whole-home backup through Tesla's Backup Gateway 2, and anyone who wants solar, battery, and (with a Tesla Wall Connector) EV charging managed in one app.
For Queensland conditions: the manufacturer specifies an operating range of -20°C to 50°C, and its enclosure rating is Indoor/Outdoor (IP 67 for battery and electronics, IP55 for wiring). In hot climates many systems reduce output at the top of their range, so we install out of direct afternoon sun with clearance for airflow wherever possible. With storm season bringing outages, the backup set-up (which circuits stay on) is something we'll design with you.
Countryside Solar supplies and installs the Tesla Powerwall 3 across Toowoomba, Dalby and our 13 service areas in Queensland. Our SAA-accredited installers handle system design, installation, commissioning and warranty registration, and the work is backed by our 25-year workmanship warranty.

A solar hybrid inverter with three MPPTs is integrated, so panels connect straight to the battery and there's one less box on the wall.
Nominal output can be set to 5 kW, 10 kW or 11.04 kW to suit your supply and network rules, with 185 A locked-rotor current for starting motors such as air conditioners and pool pumps.
Up to three Powerwall 3 Expansion units can be added to one Powerwall 3, and up to four Powerwall 3 units can be combined.
With Backup Gateway 2, the system detects outages and switches your home to battery automatically, and the Tesla app shows energy flows in real time.

Products from other categories that work well alongside the Powerwall 3.
Usually not. Powerwall 3 includes a solar hybrid inverter with three MPPTs and up to 20 kW of DC solar input. Existing systems with their own inverter can also be AC-coupled.
Yes. Tesla allows up to three Expansion units per Powerwall 3, and up to four Powerwall 3 units in one system.
The manufacturer warranty is 10 years, with battery capacity remaining at end of warranty: 70%; warranted throughput: Unlimited cycles for self consumption / Time based control / backup. 37,800 kWh for other uses. Terms may require product registration. We register it for you.
The manufacturer lists Indoor/Outdoor (IP 67 for battery and electronics, IP55 for wiring). In Queensland we still avoid direct afternoon sun where possible, because heat can reduce performance, and we'll recommend the best spot during the site visit.
Eligible installations may qualify for the Cheaper Home Batteries Program discount. We'll confirm eligibility and the current amount in your quote.
Most Queensland homes suit 10–16 kWh of usable storage. We size the Powerwall 3 from your evening usage, backup goals and solar array.
Backup capability varies by model and switchboard design. We'll explain whether the Powerwall 3 covers whole-home or essential circuits for your property.
