Search for local installers with current Clean Energy Council (CEC) accreditation and experience with your preferred battery system. Obtain at least two or three written quotes covering the battery, installation, switchboard work, warranties, monitoring and any network connection requirements. Ask whether the installer will handle approvals with your electricity distributor and confirm the proposed system is compatible with your existing solar panels. Check recent reviews, insurance and licence details, and consider having a licensed electrician assess your switchboard. Installer availability, pricing and eligibility for any government support depend on your location and circumstances, so verify current information through the CEC and official government websites.
