Often, yes. Compatibility depends on your current inverter, electrical setup and the battery you choose. A site assessment helps establish suitable options.

Only if the system includes suitable backup capability and is configured for it. Ask which circuits can be backed up, the available power and how long stored energy may last.

Cost depends on equipment, system size and installation requirements. A tailored quote should explain inclusions and site-specific costs. Rebate eligibility needs to be checked for your location and circumstances.
