This powerful Alpha ESS system captures more solar during the day, enabling you to significantly reduce grid reliance, cut electricity bills, and enjoy continuous backup power during outages — while qualifying for Australia’s federal and state battery rebate programs.

This configuration helps you:

  • Maximise solar usage day and night

💰 How are prices calculated?

We like to keep things simple and transparent, so you always know what you’re paying for — and what you’re saving.

Total Price = Battery Price – Federal Battery Rebate

All eligible battery systems receive a federal rebate based on usable capacity. The rebate is currently calculated as:

$350 × Usable kWh of the battery

For example, let’s say you’re looking at a battery system with 15 kWh usable capacity. The rebate would be:

$350 × 30.3 = $10,605.00 federal rebate

So if the system’s full retail price is $17,000, the displayed price on our website would be:

$18,150.00 – $10,605.00 = $7,545.00

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

✅ No paperwork is needed — 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 a CEC-accredited professional
  • GST included

📌 Final Quote May Vary Based On:

  • Your property’s location and accessibility
  • Switchboard condition or upgrade requirements
  • Distance between the switchboard and the battery location
  • Additional installation materials, if needed

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

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
