Search for local installers with experience in your battery brand and ask whether they are appropriately licensed and accredited, such as through the Clean Energy Council. Compare written quotes covering the battery capacity, usable storage, installation, monitoring, warranty terms and any switchboard or electrical work. Ask how the system may affect your solar export payments, electricity plan and backup power, as not every battery provides whole-home backup. Rebates and other incentives depend on your location and circumstances, so check current government information and confirm eligibility with the installer or relevant provider before signing.
