What a solar battery does

Green Edge Technologies installs solar batteries for homes and businesses in Melbourne and across Victoria. A battery stores the solar power your panels make during the day, so you can use it at night. We can install a battery with new solar panels, or add one to the solar you already have.

Solar panels make most of their power in the middle of the day. Without a battery, any power you don't use then goes back to the grid. A battery stores that spare power so you can use it in the evening and overnight.

A battery can also keep your power on in a blackout, if it's installed with backup. With backup, the battery runs the circuits you choose until the grid comes back.

The federal battery discount

The Cheaper Home Batteries Program is a federal government discount on home and business batteries. It opened on 1 July 2025, and the government changed it on 1 May 2026. The Clean Energy Regulator runs it.

The discount covers small batteries connected to new or existing solar panels. You don't need to apply for it yourself. Your accredited installer gives it to you, either off the price up front or as a rebate after the install.

The discount gets smaller over time until 2030. Because it changes, we work out the current discount when we quote.

Solar Victoria's interest-free battery loan is no longer taking applications.

Solar battery questions

How much does a solar battery cost in Melbourne?

The cost of a solar battery in Melbourne depends on the battery's size and brand, your existing solar, and whether you want backup. The federal discount also changes the price. We give you a free quote with the current discount included.

Can I add a battery to my existing solar panels?

Most existing solar panels can have a battery added, but it depends on your inverter. We check your inverter and system before we quote.

What size solar battery do I need?

The right solar battery size depends on how much power you use, when you use it, and how much solar you have. The federal government's advice is that bigger is not always better. We size your battery to how your home uses power.

Will a solar battery keep my power on in a blackout?

A solar battery keeps your power on in a blackout only when it's installed with backup. Backup runs the circuits you choose, such as lights and power points. Tell us what you want to keep running and we'll set it up.

Do I need to apply for the battery discount myself?

You don't need to apply for the Cheaper Home Batteries Program discount yourself. Your accredited installer or retailer gives you the discount. We handle it as part of your install.

Is there a Victorian government battery rebate?

Solar Victoria's interest-free battery loan is no longer taking applications. The federal Cheaper Home Batteries Program is open to Victorian homes and businesses.

Can I go off the grid with a solar battery?

Going fully off the grid needs a system designed for it from the start. That is a bigger project than adding a battery to your solar. Green Edge also installs off-grid systems. Ask us if off-grid suits your property.

Which battery brands does Green Edge install?

Green Edge installs Tesla, Sigenergy, BYD and FranklinWH batteries. We help you choose the one that suits your home, your solar and your budget.

Does Green Edge install the Tesla Powerwall?

Green Edge is a Tesla Energy Certified Installer and installs the Tesla Powerwall 3. We can talk you through how it compares with other batteries for your home.
