A solar and battery package typically combines rooftop panels, an inverter, a home battery, monitoring software and installation in one proposal. It may also include system design, grid connection paperwork, warranties and after-sales support, but inclusions vary between installers and retailers. Ask for the panel and battery capacities, expected performance, installation costs, warranty terms and what happens if a component fails. Any available rebate or incentive depends on the system, location and your circumstances, so check the current rules on energy.gov.au and confirm the final quote with an accredited installer.
