A typical home solar battery can cost roughly $8,000–$14,000 installed before any applicable incentives, although smaller and larger systems may fall outside this range. The price depends on storage capacity, battery chemistry, installation complexity, switchboard upgrades, brand and warranty, and whether you need a hybrid inverter. Eligible systems may receive support under current government schemes, but the amount and eligibility depend on the product, installer and your circumstances.
