*GREON starting figures for a standard install. Your final total comes from an itemised quote. Program rules: Clean Energy Regulator.

Cost per kWh falls as the stack grows. A 13.99 kWh usable capacity costs about $571 per unit of storage, and a 37.2 kWh battery costs about $457. Homeowners start small, then expand as energy needs grow. GREON recommends the right battery size for your household.

Compare any Alpha ESS battery price in Australia line by line: battery, inverter, installation and warranty. Alpha solar battery price offers differ between installers. An offer without switchboard work looks cheaper upfront. GREON beats any genuine comparable quote within 30 days. Every Alpha ESS solar battery price we quote already includes the STC discount.

  • WHAT'S INCLUDED

What's Included in Your Alpha ESS Battery Quote

Every GREON Alpha ESS quote covers 4 components: battery modules, the inverter, cabling and protection, and installation with paperwork. Each component appears as its own line, so you see where every dollar goes.

Alpha ESS Battery Modules

LFP storage sized to your evening usage, in 13.99kWh modules on the M5 and M10. Alpha ESS Australia backs the product warranty.

Hybrid or Battery Inverter

A 5 kW hybrid inverter pairs with 1 or 2 modules, and a 10 kW hybrid inverter pairs with 3 modules. The inverter appears inside every figure.

Cabling and Protection

Cabling, isolators and protection devices. Switchboard upgrades appear as a separate line.

Installation and Paperwork

Australian installers fit and test the system, set up the monitoring app, lodge your rebate claim and apply to Energex or Ergon. A 10-year GREON warranty covers the work.

  • PRICE FACTORS

What Changes the Price of an Alpha ESS Battery?

6 factors set every Alpha ESS installation cost in QLD: capacity and model, your inverter size, main board condition, storeys, cable distance and power supply type. GREON prices each factor as a separate line.

Battery Size and Model

Capacity moves the figure most: each module adds 13.99kWh, and 3 modules take the 10kW inverter.

Inverter Size

Every GREON Alpha ESS system includes a hybrid inverter, 5kW for 1 or 2 modules and 10kW for 3 modules.

Main Board Condition

Older boards need protection work to meet Australian standards. GREON checks yours from a photo.

Roof Type and Storeys

Double storey homes and tile roofs add labour. Single storey homes with metal sheeting stay at the standard rate.

Cable Distance

Each extra metre from the main switch adds cable and labour.

Power Supply Type

Single phase homes use the M5 or M10. Three-phase homes compare other brands on our [Solar Batteries in Australia] page

  • THE REBATE

How Much Is the Federal Rebate on an Alpha ESS Battery?

The Cheaper Home Batteries Program takes about $3,615 off a 13.99kWh Alpha ESS SMILE-M5-S installed before 1 January 2027. Every kWh up to 14 earns the full STC factor of 6.8, and GREON deducts the saving before you pay.

The Clean Energy Regulator runs the scheme through small-scale technology certificates (STCs), each worth about $38.

A 13.99kWh M5-S earns about $3,615, a 27.98kWh system about $5,785 and a 41.97kWh system about $6,330.

Install Before 1 January 2027

The factor drops from 6.8 to 5.7 on 1 January 2027, set by installation date, not contract date. The same 13.99kWh battery then earns about $3,030, a $585 drop.

Queensland Battery Booster Status

The Queensland Battery Booster closed in May 2024, according to the Queensland Government, so the federal battery rebate is the only upfront incentive for QLD homes.

GREON checks eligibility and lodges the paperwork. Full rules: [solar battery rebate guide].

  • GET SIZED RIGHT

How GREON Sizes the Right Alpha ESS Battery for Your Home

GREON sizes every Alpha ESS battery from 3 inputs: your consumption after dark, your solar system output and your backup needs. We recommend the smallest capacity that covers all 3, not the largest option.

01

Night-Time Use

Your last 2 power bills show consumption after dark and set the base capacity.

02

Solar System Output

A 6.6kW solar system produces about 26kWh on a clear day, enough to fill 14kWh. Larger 10.5kW and 13.3kW systems produce about 41kWh to 52kWh.

03

Backup Needs

Backup cover adds capacity for appliances kept running in an outage.

Send your storeys, supply type and a recent power account for a sized proposal within hours.

  • YOUR SAVINGS

How Much Can an Alpha ESS Battery Save You Each Year?

An Alpha ESS battery saves about 30c for every kWh of solar used after dark instead of exported. A home shifting 10 kWh a day saves about $3 daily, or about $1,095 annually, before VPP credits.

Solar exports earn little in Queensland. Ergon’s regional feed-in tariff is 6.006c/kWh for 2026 to 27, and SEQ retail offers sit between 0c and about 10c.

Helensvale Retrofit on a 6.6kW System

A couple kept their panels and added a 13.99kWh M5-S with a new hybrid inverter. Air con and cooking now run on battery power after dark.

Coomera New Build With the 13.3kW Package

New owners paired a 13.3kW solar system with a 41.97kWh M10 and claimed the panel and battery rebates in one visit.

Hope Island EV Home With 42kWh

A 41.97kWh M10 charges the car from stored solar energy instead of grid power.
  • Every Alpha ESS battery GREON installs is VPP-ready, so owners can join a virtual power plant for extra credits. Examples are illustrative, based on current tariffs and a 30c gap between import and export rates.
  • BACKUP POWER

Does an Alpha ESS Battery Provide Backup Power in a Blackout?

Yes, when GREON designs for it. The M5 and M10 switch to UPS-grade supply in under 20ms, powering a protected sub-board wired to the circuit list you choose.

  • Emergency output on the inverter, which isolates from the grid automatically
  • A sub-board that separates chosen wiring from the rest of the house
  • A short list of must-have appliances, such as the fridge, lights, Wi-Fi and fans

Storm season from October to March brings the most outages to SEQ. A 13.99 kWh battery runs those appliances for about 1 to 2 days without grid power.

Tell GREON this matters when you request a figure, so the design includes it from day one.

  • ADD TO YOUR SOLAR

Add an Alpha ESS Battery to Your Existing Solar System

Most owners keep their solar panels when adding an Alpha ESS battery. GREON pairs the battery with a 5kW or 10kW hybrid inverter, so your panels, rails and wiring stay in place.

Panels Stay Put

Panels, rails and wiring stay in place, and the battery charges before any export.

Hybrid Inverter Included

The hybrid inverter in every quote runs your panels and battery as one system.

One-Phase Supply

One-phase supply pairs with the M5-S or M10. Three-phase homes compare other brands on our [Solar Batteries in Australia] page.

Solar and Battery Tracking

The Alpha ESS app shows solar generation, battery charge and energy use in real time.

EV Charger Installation

GREON fits an EV charger beside your battery, so the car charges from stored solar instead of the grid.

Planning new panels and a battery together: compare our [Solar + Battery Packages] or read the [Solar + Battery Installation Process].

  • WHY WE CHOOSE IT
