💰 How are prices calculated?

Total Price = Battery Price – Federal Battery Rebate

All eligible battery systems receive a federal rebate based on usable capacity:

$350 × 18.64 kWh = $6,524.00 federal rebate

If the full retail price is $13,002.00, the displayed price would be:

$13,002.00 – $6,524.00 = $6,478.00 

This is the amount you’d typically pay (incl. GST) for standard installation. 

✅ No paperwork is required — we apply the rebate upfront and handle the claim process for you.

✅ Our Online Price Includes:

  • The full battery + hybrid inverter bundle
  • Federal rebate already applied
  • Standard installation in metro areas
  • Monitoring app setup and commissioning
  • Certified installation by CEC-accredited professionals
  • GST included

📌 Final Quote May Vary Based On:

  • Property location and accessibility
  • Switchboard condition or upgrades required
  • Distance between switchboard and battery location
  • Additional installation materials, if needed

We provide a personalised quote before any work begins — no surprises, no pressure.

Plan Your Install

🛠️ Plan Your Install

Before we can confirm your quote or schedule an installation, we need to understand a bit about how and where you'd like the battery installed.

  • ✅ Whether you're installing the battery inside (garage) or outside (side of house)
  • ✅ Whether your system is being installed as an AC-Coupled setup (added to an existing solar system), or a DC-Coupled setup (as part of a new installation or replacing an exising inverter)

These options affect:

  • How the system is wired
  • Where components can be safely mounted
  • What rebates may apply
  • The type of photos we’ll need from you

FAQs

❓ Frequently Asked Questions

Q:  Will the FoxESS Home Battery System work during a blackout?

A: Yes — many FoxESS home battery systems include built-in backup and emergency power functionality (when installed with compatible hybrid inverters and backup configurations). This allows the system to supply electricity to essential circuits such as lights, refrigerators, Wi-Fi, and other critical appliances during a blackout. Depending on the model, you can access several kilowatts of backup and surge capacity to keep your home powered when the grid goes down.

Q: How much can I save using the FoxESS Home Battery System?

A: You can save hundreds of dollars per year by storing excess solar energy generated by your solar panels and using it during peak tariff periods instead of drawing electricity from the grid. By maximising self-consumption and reducing reliance on rising energy prices, a FoxESS battery system helps improve overall solar return on investment. Actual savings will depend on your household energy usage, solar production, and local electricity rates.

Q: Can the FoxESS home battery be installed on an existing solar system?

A: Yes — FoxESS batteries and hybrid inverters are designed to be compatible with many existing solar systems (subject to technical assessment and inverter compatibility). Our installation team will review your current solar setup during the quotation and site inspection process to confirm whether a FoxESS battery solution is suitable for your system.
