Supercharge Your Solar with BYD Battery Storage

The solar revolution is in full swing, with over 30% of Aussie homes now powered by rooftop solar. While solar panels alone help slash power bills and reduce carbon emissions, they don’t always meet your energy needs—especially once the sun goes down.

Here’s where battery storage makes a game-changing difference.

During the day, your Trina solar panels generate clean energy, which your Fronius inverter converts into usable AC power. But many households aren’t home to use all that energy during daylight hours—so it gets sent back to the grid for a small credit. At night, you’re back to buying electricity at peak rates.

That’s why Eco Sparky installs the BYD Battery-Box Premium alongside our solar systems. It stores your unused solar energy so you can use it after dark or during cloudy weather, reducing your reliance on the grid and protecting you from rising electricity costs.

Why Add a Battery?

Energy Independence – Store your own solar power and use it when it suits you
More Solar, Less Grid – Use your self-generated power day and night
Peak Tariff Protection – Reduce your need to buy expensive electricity
Cleaner Backup Power – Keep the lights on during outages without noisy generators
Future-Ready for EVs – Charge your electric vehicle at home, with your own power

According to the Climate Council, adding just a 4kWh battery to a 5kWh solar system can increase your solar self-use from 30% to 60%. That’s massive savings—and massive impact.

Why We Recommend BYD + Fronius

Eco Sparky installs both Tesla Powerwall and BYD batteries, but for many homes, the BYD + Fronius combo is the perfect pairing:

🔹 BYD Battery-Box Premium – Modular, safe, and scalable
🔹 Fronius GEN24 Inverter – Smart, hybrid-ready, and battery-compatible
🔹 Trina Solar Panels – High efficiency and built for Australian rooftops
🔹 Clenergy Tilt Frames – Maximise solar generation year-round

This setup delivers top-tier performance, energy insights via Fronius Solar.web, and the flexibility to expand storage as your needs grow.

Battery FAQ’s

Why install a Battery?

In a world where energy costs are soaring and our reliance on electricity continues to grow, integrating a battery into your home's energy system holds a plethora of advantages. Whether you're driven by economic sensibilities, a desire to reduce your environmental impact, ensuring uninterrupted power supply, or preparing for the electrified future, the decision to install a battery is both smart and forward-thinking.

  • Economical Advantage: If your solar setup is substantial or your energy consumption pattern aligns with peak-hour tariffs, a battery becomes a savvy investment. As electricity prices surge, tapping into your self-generated power during the day or off-peak hours grants you greater independence from the grid, translating to significant savings over time.

  • Eco-Friendly Footprint: By embracing the combination of solar panels and batteries, you're embracing a power solution that operates without a trace of emissions. These technologies work quietly and diligently to capture, store, and dispense clean, untainted energy, reducing your carbon footprint while contributing to a more sustainable planet.

  • Reliable Resilience: Imagine never being left in the dark during a power outage. While traditional generators are a common choice, some batteries offer a cleaner and hassle-free alternative! Swiftly switching on to power your essentials when the grid falters, batteries grant you peace of mind without the noise, pollution, and ongoing maintenance costs associated with generators.

  • Electrify Your Future: With each battery installation, you're not merely enhancing your home's energy system, but also taking a decisive step toward electrifying your future. As the world gravitates toward renewable energy and cleaner technologies, your battery-equipped home becomes a microcosm of progress, where you can fully harness the potential of solar energy, reduce your carbon impact and gain energy independence.

  • Empower Your EV transition: As society transitions toward electric vehicles (EVs), preparing your home for this shift has never been more relevant. By installing a battery now, you're securing a seamless and convenient charging solution for your future EV. Fuelling your sustainable journey right from your home ensures effortless and cost-effective strides toward cleaner and cheaper transportation!

What incentives are available for Batteries in NSW?

In NSW, homeowners and businesses can get incentives for battery installations, particularly when paired with existing solar systems. The NSW Government offers a rebate program, providing discounts of $1,600 to $2,400 on upfront installation costs of batteries. Additionally, there's a Virtual Power Plant (VPP) incentive of $250 to $400 for connecting the battery to a VPP, which can be claimed twice within a six-year period. 

Can you add a battery to an existing solar system?

In most cases it is  possible to add a battery to an existing solar system, however it can be tricky depending on whether or not your system was designed with the possibility of doing so in the first place. For those in the process of installing solar, a hybrid inverter can be a great way to ensure your system is ready to add a battery whenever that makes the most financial sense for your situation. 

Will I need more panels?

The necessity for additional solar panels to charge a battery at home largely depends on your current solar setup, energy consumption, and the battery capacity you wish to install. If your existing solar array generates surplus energy beyond what you use during daylight hours, you might have the potential to charge a battery without needing more panels. However, if your solar production doesn't exceed your daily consumption, you might consider adding more panels to ensure sufficient energy generation to both power your home and charge the battery. Before making any decision, it's advisable to consult with a professional solar energy technician like Eco Sparky. We can assess your energy needs, evaluate your current solar capacity, and recommend the optimal solution.
