Choosing a Fronius battery installer

• Accreditation: the installer must be accredited by Solar Accreditation Australia (SAA) for batteries, or the battery won't qualify for the federal discount. Ask for their accreditation number.
• The exact model: check the quoted Fronius model is on the approved list above, with its usable capacity in kWh.
• The inverter: Fronius makes inverters too. Ask whether the battery is paired with a Fronius inverter or a compatible one from another brand, and confirm it can join a virtual power plant (VPP), which the federal discount requires.
• Backup: ask what keeps running in a blackout and whether backup costs extra.
• Warranty: ask how the Fronius warranty is registered, what capacity it guarantees, and who to call if something goes wrong.
• The discount: the federal discount should be shown as its own line on the quote, so you can compare quotes fairly.
