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.
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.
LFP storage sized to your evening usage, in 13.99kWh modules on the M5 and M10. Alpha ESS Australia backs the product warranty.
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, isolators and protection devices. Switchboard upgrades appear as a separate line.
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.
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.
Capacity moves the figure most: each module adds 13.99kWh, and 3 modules take the 10kW inverter.
Every GREON Alpha ESS system includes a hybrid inverter, 5kW for 1 or 2 modules and 10kW for 3 modules.
Older boards need protection work to meet Australian standards. GREON checks yours from a photo.
Double storey homes and tile roofs add labour. Single storey homes with metal sheeting stay at the standard rate.
Each extra metre from the main switch adds cable and labour.
Single phase homes use the M5 or M10. Three-phase homes compare other brands on our [Solar Batteries in Australia] page

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.
60% of the factor
A 13.99kWh M5-S earns about $3,615, a 27.98kWh system about $5,785 and a 41.97kWh system about $6,330.
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.
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].
Most households fit 1 of 3 Alpha ESS capacities: 14kWh for essentials, 28kWh for growing households and 42kWh for EV owners. The 14kWh option sits fully in the 100% tier, so it has the lowest entry price at $4,621*.
For 2 to 4 people running air con and cooking after dark.
For 4 to 6 people with a pool pump or home office.
For households that charge an electric vehicle overnight.
Every option carries 10 years of Alpha ESS warranty cover and backup for essential circuits.
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.
Your last 2 power bills show consumption after dark and set the base capacity.
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.
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.
GREON installs 2 Alpha ESS options from the SMILE series. Capacity runs from 13.99kWh to 41.97kWh, every unit uses lithium iron phosphate cells, and the performance warranty guarantees 70% retained capacity after 10 years.
Every Alpha ESS system includes a hybrid inverter, and the full datasheet comes with your quote.
The M5-S suits one-phase homes needing 14kWh or 28kWh, and the M10 suits heavy daily use with 42kWh. Both use LFP chemistry and carry a 10-year warranty.

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.
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.
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.
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, rails and wiring stay in place, and the battery charges before any export.
The hybrid inverter in every quote runs your panels and battery as one system.
One-phase supply pairs with the M5-S or M10. Three-phase homes compare other brands on our [Solar Batteries in Australia] page.
The Alpha ESS app shows solar generation, battery charge and energy use in real time.
GREON fits an EV charger beside your battery, so the car charges from stored solar instead of the grid.
