FEDERAL GOVERNMENT PROGRAM

Australian Government Cheaper Home Batteries Program

The Australian Government announced the Cheaper Home Batteries Program as part of the 2024-25 Federal Budget under the Powering Australia and Future Made in Australia plan. It provides interest-free loans through the Clean Energy Finance Corporation (CEFC) for eligible households installing approved battery storage systems.

The goal: reduce battery costs by around 30%. WA homeowners can potentially stack this with Synergy's Distributed Energy Buyback Scheme (DEBS) (currently 2.5 c/kWh for new connections) for maximum savings. s.

STC REBATE TIERS

STC Rebate Tiers: How Battery Size Affects Your Rebate

Under the Small-scale Technology Certificate (STC) scheme (see the Clean Energy Regulator's STC guidelines), the rebate factor applied to battery storage systems is tiered by capacity:

Battery Capacity	STC Factor
0 to 14 kWh	100% of the STC factor
14 to 28 kWh	60% of the STC factor
28 to 50 kWh	15% of the STC factor

Why 14 kWh Is the Sweet Spot

A battery sized up to 14 kWh receives the full 100% STC factor, meaning you get the maximum upfront rebate per kilowatt-hour of storage. Popular batteries like the Tesla Powerwall 3 (13.5 kWh usable) fall just under this threshold, which is one reason they are so common in Perth homes. Check the CEC approved battery product list for eligible models.

Why 28 kWh Matters for Larger Homes

If you need more than 14 kWh of storage, the capacity between 14 kWh and 28 kWh still attracts 60% of the STC factor. This makes a dual-battery setup (e.g. two 13.5 kWh units totalling 27 kWh) a smart choice for larger homes or households with high overnight energy use: you stay within the 28 kWh threshold where the rebate is still meaningful.

What Changes from 1 May 2026

From 2026, the STC deeming period shortens, reducing the total number of STCs generated for any battery installation. This means the dollar value of all three tiers decreases. Homeowners who install before the May 2026 reduction lock in the higher rebate. For a 14 kWh system at 100% factor, the difference between installing now versus after May 2026 can be several hundred dollars. For a 28 kWh dual system, the saving is even larger.

The key takeaway: Size your battery at 14 kWh or below to maximise the per-kWh rebate. If you need more capacity, staying under 28 kWh keeps you in the 60% tier. Above 28 kWh, the rebate contribution drops sharply to 15%, making very large systems harder to justify on rebate value alone. Call 1300 717 583 to discuss the right size for your Perth home.

WHY IT MATTERS

Why Does Getting Perth Battery Installation Right Matter from Day One?

A battery system that is incorrectly sized, incompatibly paired, or poorly wired may work initially, but will underperform, degrade faster, or develop safety issues over time. In Perth's hot climate, correct placement in a shaded or cool location is also essential for battery longevity and warranty compliance. Getting it right at installation avoids expensive corrections later.

Our approach starts with a thorough assessment of your existing solar system, inverter compatibility, and energy usage. We only recommend a battery if it is genuinely compatible and will deliver meaningful benefits for your household. We also guide eligible customers through the WA Residential Battery Scheme rebate process.

We assess your system before recommending a battery, and help eligible Perth customers access WA battery rebates.

PRE-INSTALLATION

What Does Ares Energy Check Before Recommending a Battery in Perth?

A battery recommendation without this assessment is just a guess.

Inverter Compatibility

Not all inverters support battery storage. We check your inverter model, firmware version, and communication capability before any recommendation.

Energy Usage Profile

We review your consumption patterns, particularly evening and overnight usage, to determine whether battery storage will actually benefit you.

Existing Solar System

System size, panel output, and current generation data all influence the right battery capacity. We review your existing setup in detail.

Placement & Ventilation

Battery location must meet clearance, ventilation, and fire separation requirements. We identify a compliant installation location before proceeding.

Electrical Protection

We verify that your switchboard and existing wiring can safely support the addition of battery storage with correct protection devices.

Export Limits & Feed-In

Grid export restrictions and feed-in tariff arrangements affect whether a battery adds real value. We factor these into our assessment.

Common questions

Frequently Asked Questions: Perth Battery Installation

What battery rebates are available for Perth homeowners in 2026?

Eligible Synergy customers can receive up to $5,000 rebate plus a $10,000 interest-free loan under the WA Residential Battery Scheme for batteries installed from 1 July 2025. The federal Cheaper Home Batteries Program provides additional subsidy on top. You must use a CEC approved installer and join an approved VPP program to qualify.

Do I need to join a Virtual Power Plant (VPP) to get the WA battery rebate?

Yes. Participation in an approved Virtual Power Plant program is a mandatory condition of the WA Residential Battery Scheme. This allows your battery to assist the grid during peak demand. Ares Energy will guide you through VPP enrolment options as part of your installation.

Is my existing solar inverter compatible with a home battery?

Not all inverters support battery addition. Compatibility depends on the inverter brand, model, firmware version, and communication protocol. Ares Energy performs a full inverter compatibility assessment before making any recommendation. We only proceed if your system can reliably support battery integration.

What is the difference between AC-coupled and DC-coupled battery systems?

DC-coupled systems connect the battery before the inverter, generally offering higher efficiency. AC-coupled systems connect on the AC side after the inverter, making them easier to retrofit to existing solar installations. The right choice depends on your inverter type and existing system design. Ares Energy assesses your setup and recommends the optimal solution.

Which battery brands does Ares Energy install in Perth?

Ares Energy has experience installing Tesla Powerwall 3, Sungrow SBR, Sigenergy, and Alpha-ESS batteries across Perth homes. We assess inverter compatibility and recommend the most suitable brand and capacity for your specific system and energy usage.

Will my battery charge from the grid overnight if solar doesn't produce enough?

Most modern battery systems can be configured to charge from the grid during off-peak hours when solar generation is insufficient. Ares Energy configures your battery charge settings to optimise self-consumption and align with your Synergy tariff arrangement.

What happens to my battery warranty if installed by an uncertified installer?

Most battery manufacturers require installation by a CEC approved installer to maintain warranty validity. Installation by an uncertified installer can void the product warranty entirely. Ares Energy is CEC approved and provides full compliance documentation including a Certificate of Electrical Compliance with every installation.

Is the Federal Home Battery Program available in Perth, WA?

Yes. Eligible WA homeowners can apply through the Clean Energy Finance Corporation (CEFC) as part of the Australian Government's Cheaper Home Batteries Program. The program provides interest-free loans to reduce upfront battery costs by around 30%. Ares Energy can help assess your eligibility and find the right battery for your home.

What size battery gets the best STC rebate in Perth?

Under the federal STC scheme, batteries up to 14 kWh receive 100% of the STC rebate factor, making them the most cost-effective choice for maximising your upfront savings. Capacity between 14 kWh and 28 kWh attracts 60% of the factor, while above 28 kWh only 15% applies. A 13.5 kWh battery like the Tesla Powerwall sits just under the 14 kWh threshold for full rebate eligibility. For current rebate estimates based on your home's needs, call Ares Energy on 1300 717 583.

Will battery rebates reduce after May 2026?

Yes. The STC deeming period shortens each year, reducing the upfront rebate value on new battery and solar installations. Installing in 2025 or early 2026 means you receive the higher current rebate before the May 2026 step-down. Call us on 1300 717 583 for current pricing.
