Whether you're adding a battery to solar you already have or getting solar and a battery together, tell us your postcode and a few details about your home. We'll share your request with up to 3 participating installers who service your area. It's free, and there's no obligation to accept a quote.

The federal battery discount in Perth

Perth homes can get the federal Cheaper Home Batteries Program discount. For batteries installed from 1 May 2026 to 31 December 2026, each kWh of usable capacity earns 6.8 certificates, at a lower rate above 14 kWh. At $38 a certificate (installers trade them at the market price, which varies), that works out at:

  • 10 kWh usable: 68 certificates, about $2,584
  • 13.5 kWh usable: 91 certificates, about $3,458
  • 20 kWh usable: 119 certificates, about $4,522
  • 30 kWh usable: 154 certificates, about $5,852
  • From 1 January 2027 the rate drops to 5.7 certificates per kWh, so the same 13.5 kWh battery would get about $2,888.
  • The battery must be installed with new or existing solar, be able to join a virtual power plant (you don't have to join one), be on the Clean Energy Council's approved list and be installed by an accredited installer.
  • Your installer normally takes the discount off the quoted price. In WA you may also be able to get the WA Residential Battery Scheme rebate (see below).

Connecting a battery in Perth

Perth is on Western Power's network. Western Power needs an application whenever a battery is added, and its rules changed on 1 May 2026.

  1. Step 1: An application to Western Power

    Adding a battery needs an Embedded Generation Connection application, like a new solar system. Homeowners are responsible, and most authorise their installer to apply.

  2. Step 2: New rules from 1 May 2026

    New and upgraded systems, including ones adding a home battery, must meet the new requirements. A base CSIP-AUS capability is needed to connect, and extra battery features are only required if you're claiming the WA rebate (they also let the battery join a virtual power plant).

  3. Step 3: Up to 30 kVA

    A standard household connection can now take up to 30 kVA of inverter capacity, solar and battery together, single or three phase.

The WA battery rebate and buyback rates

  • WA Residential Battery Scheme: Synergy customers can get $130 per kWh of usable capacity, up to $1,300 (rebates apply to usable capacity up to 10 kWh), for a battery of at least 5 kWh. One rebate per property.
  • Interest-free loans of $2,001 to $10,000 over three to ten years, for households with a gross income under $210,000. The loan and rebate together can't exceed the cost of the system.
  • You must join a virtual power plant to get the rebate or loan. Synergy customers can choose Synergy's or an approved alternative.
  • Synergy's DEBS buyback pays 10 cents per kWh for exports between 3 pm and 9 pm, and 2 cents at other times, so a battery that exports in the evening earns five times the midday rate.

Keeping the power on in a blackout

Not every battery provides backup, and those that do may only cover some circuits. Ask which circuits stay on, how quickly the backup takes over, and whether your solar keeps charging the battery during a long outage.

What stays on depends on how the system is set up. Ask each installer which circuits are on backup, how quickly it switches over, and whether solar keeps charging the battery during a long outage.

Where the battery can go

The battery installation standard, AS/NZS 5139, limits where a battery can be installed. Among other places, it can't go:

  • Inside a habitable room, such as a bedroom, lounge, kitchen or study
  • In a ceiling space or wall cavity, or under a staircase
  • On an evacuation or escape route
  • Within 600 mm of a doorway, a window into a habitable room, or an appliance

Worth asking about in Perth

  • Check your Wi-Fi reaches where the battery's inverter will go: it needs to stay online for export rules, and to join a virtual power plant.
  • Claiming the WA rebate? Get conditional approval before installation, and make sure the battery is installed within six months.
  • In a townhouse or unit? Wall space for a battery is often common property, so check with your owners corporation or strata company before you get quotes.
  • All electrical work must be done by a licensed electrician. Ask for the installer's licence and accreditation details with the quote.

Frequently asked questions

Is there a battery rebate in Perth?

Yes: the federal Cheaper Home Batteries Program, plus the WA Residential Battery Scheme for Synergy customers (up to $1,300, or an interest-free loan), which needs you to join a virtual power plant.

How much is the discount on a 13.5 kWh battery?

For a battery installed by 31 December 2026, 91 certificates, or about $3,458 at $38 a certificate. The certificate price varies, so check the amount on each quote.

Can I add a battery to my existing solar in Perth?

Usually, yes. It needs your network's approval like a new system, and the battery's inverter counts towards your connection's limits. Ask installers whether your existing inverter can be kept or needs replacing.

Will a battery keep my power on in a blackout?

Only if it's installed with backup. Many batteries can provide it, but some cover only selected circuits and some need extra equipment. Ask each installer exactly what stays on.

What size battery do I need?

Start with how much power you use from late afternoon until morning. Our guide and the rebate calculator show how capacity, solar size and the federal discount fit together.
