Installation & rebates

Your package quote includes the specified battery, inverter, standard installation, commissioning and handover. We confirm your postcode, site conditions and rebate eligibility before you accept.

Eligible rebates are deducted in your written quote. Eligibility, approved usable capacity and installation date determine the amount; federal battery STCs apply to at most the first 50kWh of eligible usable capacity.

Gateway hardware, extra backup circuits, solar panels, switchboard upgrades and other site works are included only when listed. Any additional work is agreed before installation.

Warranty & returns

GoodWe’s current Australian inverter terms (Rev 5.8, July 2026) list 10 years for the ESA single-phase and three-phase families. The linked BAT 5.1/8.3 terms provide 10-year product and conditional performance cover, with a 70% retention threshold and a throughput limit of 3MWh per kWh of usable capacity. Time, throughput and operating conditions apply.

Accessories have separate cover, and the battery and inverter documents use different start-date rules. Read the applicable documents for claims, exclusions, freight and labour conditions. Solfuture installation workmanship cover and any additional cover must be stated in the quote. Australian Consumer Law rights remain available.

Contact Solfuture before arranging a return or cancelling an installation. Your agreed terms explain the process, and Australian Consumer Law rights continue to apply.
