A practical solar battery checklist should cover usable capacity, expected daily cycling, battery chemistry, inverter compatibility and whether whole-home or selected-circuit backup is needed. Check the product and workmanship warranties, monitoring features, installation location, ventilation, safety requirements and how the system will work during a blackout. Ask for itemised quotes covering equipment, labour, switchboard changes, approvals and ongoing costs, and confirm the installer is appropriately licensed. Rebate and feed-in tariff arrangements vary by state and circumstances, so check current information on energy.gov.au and with your installer before making a decision.
