As more Victorian households embrace solar energy, one question keeps coming up — “Should I invest in a solar battery?”
Solar batteries are the missing piece that lets you store excess solar energy and use it anytime — day or night.
But before you make the leap, it’s normal to have questions.
Here are the 10 most common questions homeowners ask about solar batteries — and our expert answers.
1️⃣ What does a solar battery do?
A solar battery stores the extra power your solar panels generate during the day. Instead of sending that energy back to the grid, it saves it for later use — like at night or during cloudy weather.
👉 Result: More self-sufficiency and lower electricity bills.
2️⃣ How much energy can a solar battery store?
Modern systems, like the FOX ESS series offered by Greentastic Pty Ltd, can store between 10 kWh and 42 kWh of power — enough to run an average home through the night.
3️⃣ Will a battery reduce my power bills?
Yes — by up to 80 % in many cases!
By using your stored energy first, you’ll draw much less electricity from the grid, especially during peak pricing hours.
4️⃣ Are solar batteries worth it in Victoria?
Absolutely. With Victoria’s Solar Homes Program and Victorian Energy Upgrades (VEU) rebates, solar batteries have never been more affordable. Rebates can cut thousands off the upfront cost.
5️⃣ How long do solar batteries last?
Most high-quality batteries — such as the FOX ESS range — come with a 10-year performance warranty and are engineered to last even longer with proper use and maintenance.
6️⃣ Can I add a battery to my existing solar system?
Yes! If you already have panels, a compatible solar battery can be easily integrated.
Greentastic’s experts can assess your current setup and recommend the best battery option for maximum efficiency.
7️⃣ What happens during a blackout?
Unlike standard solar systems, a battery can keep your home powered during outages.
With backup capability, essential appliances — lights, fridge, Wi-Fi — stay on, even when the grid goes down.
8️⃣ How safe are solar batteries?
Very safe. FOX ESS batteries are Clean Energy Council (CEC) approved and built with advanced lithium-iron-phosphate (LiFePO₄) technology, which is more stable and reliable than older battery chemistries.
9️⃣ How long does installation take?
A standard installation usually takes one to two days, depending on your home’s electrical setup.
Greentastic’s certified installers ensure everything is tested, approved, and ready to perform safely.
🔟 What’s the average cost of a solar battery system?
Prices vary by size and brand, but Greentastic Pty Ltd currently offers exclusive deals on FOX ESS 41.9 kWh systems — starting from $5,999 installed (after rebates).
That’s a powerful system for a fraction of typical market pricing!
