Overview

📦 About This Bundle

The Alpha ESS 39.9 kWh Battery, paired with the SMILE5-INV 5KW Hybrid Inverter (supporting up to 7.5 kW PV input), delivers a powerful and scalable home energy storage solution designed for large homes, EV charging households, small commercial sites, and off-grid capable living.

This advanced Alpha ESS system enables you to store a large amount of solar energy, significantly reduce grid reliance, and maintain essential operations during blackouts — while accessing federal and state rebates for strong financial returns.

This configuration helps you:

  • Use more solar during night-time and peak-rate hours
  • Lower electricity bills with increased self-consumption
  • Maintain household and business continuity during outages
  • Benefit from generous government rebates

With 39.9 kWh usable battery storage and a 5 kW hybrid inverter, this system offers:

  • Efficient charging from up to 7.5 kW rooftop PV
  • Smooth single-phase power delivery for residential circuits
  • Seamless automatic transition between solar, battery and grid

This setup can typically support large household loads — including HVAC systems, refrigeration, water pumps, EV charging, and continuous appliances — for 28–48 hours, depending on usage.

With a 10-year manufacturer warranty, Alpha Cloud smart monitoring, and CEC-accredited installation, this system provides powerful energy independence, reliability, and outstanding long-term savings.

💰 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 × 39.9 = $13,965.00 federal rebate

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

$23,760.00 – $13,965.00 = $9,795.00

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
