Solar Batteries in Mackay
Solar Batteries: The Smart Upgrade for Your Mackay Home
Solar power has long been a great way to cut electricity bills, but with feed-in tariffs offering lower returns and battery technology now more efficient than ever, adding storage is the next step.
For homeowners in Mackay, installing a solar battery makes perfect sense.
A battery allows you to store excess energy from the day and use it at night, reducing reliance on the grid and maximising your savings. Whether you want greater energy security or to get the most out of your solar system, a battery is the key to unlocking its full potential.
Why Add Solar Battery Storage to Your Mackay Home?
A solar battery lets you store excess solar energy for use when you need it most—whether at night, during peak rate periods, or in a power outage. Instead of sending electricity back to the grid for minimal returns, you can use more of the energy your system generates, maximising your savings and improving your home’s energy efficiency.
Here’s why adding a solar battery is a smart move:
- Lower Electricity Bills – Reduce your reliance on the grid and avoid rising energy costs.
- Increased Self-Consumption – Keep more of your solar energy instead of relying on feed-in tariffs.
- Backup Power – Keep essential appliances running during blackouts.
- Energy Security – Store energy for when you need it most, improving your home’s resilience.
- Optimised Solar Use – Make the most of your solar system by using stored power during peak times.

Save More with a Home Battery in Mackay
A solar battery doesn’t just store energy—it stores savings. Instead of sending excess solar back to the grid for a low feed-in rate, a home battery lets you use your own power when it’s worth the most.
That means:
- Using stored energy during peak times to avoid high electricity rates
- Maximising your solar usage instead of buying from the grid
- Reducing your energy bills by hundreds—sometimes thousands—each year
With the right setup, many Mackay homeowners are seeing payback in just a few years—and real savings for the long haul.
A solar battery can cut your reliance on the grid and turn your system into a long-term bill-buster.

Frequently Asked Questions
How much is the federal battery rebate in Mackay?
The federal Cheaper Home Batteries Program currently takes around $252 per usable kWh off the first 14 kWh of an eligible battery. For a typical 13.5 kWh home battery that’s roughly $3,400 off, applied as an upfront discount on your quote. Capacity between 14 and 28 kWh gets 60% of that rate, and capacity between 28 and 50 kWh gets 15%. The rate steps down every six months, with the next reduction on 1 January 2027, and Energy Base handles all the rebate paperwork for you.
Can I add a battery to my existing solar system?
Yes, in most cases. The federal rebate applies to batteries added to existing solar as well as new solar and battery packages. Your solar system needs to be grid-connected and up to current standards, and some older inverters may need upgrading or a separate AC-coupled battery (a battery with its own inverter that works alongside your existing one). We check your current setup during a free site inspection and tell you exactly what will and won’t work.
Are solar batteries worth the investment?
Every household has different energy needs, but with lowering feed-in tariffs, rising electricity prices, and increasing inflation, there’s never been a better time to invest in battery storage.
A solar battery allows you to store excess energy instead of exporting it at low rates, helping you use more of your solar power and avoid high-cost grid electricity. Plus, with backup power during blackouts, a battery adds extra security to your home’s energy supply.
If you want to reduce energy costs and increase your energy resilience, a solar battery is a worthwhile investment.
What is the best battery size for my home?
Battery size depends on your energy usage, solar system size, and household needs. However, for most homeowners, a battery between 10–14kWh offers the best balance of affordability, storage capacity, and long-term savings. Our team can assess your energy profile and recommend the most suitable battery size for your home.
Which battery brands does Energy Base install?
We install BYD, Sigenergy, FranklinWH, Sungrow and Tesla Powerwall. All five are approved for the federal rebate and have a strong track record in Queensland’s heat and humidity. Each suits a different type of home: Tesla Powerwall and FranklinWH are all-in-one units with built-in backup, Sigenergy and Sungrow pair well with their own hybrid inverters, and BYD is modular so capacity can be expanded later. We’re a Tesla Powerwall Certified Installer and recommend the brand that fits your usage and budget, not a one-size-fits-all package.
What types of solar battery technologies are available?
The most common options include:
- Lithium-ion batteries – Known for efficiency, longevity, and fast charging, making them the preferred choice.
- Lead-acid batteries – A more budget-friendly alternative but generally less durable and efficient.
- Advanced technologies – Options like lithium titanate offer specialised benefits for unique energy needs.
Our team can help you select the best battery for your home and energy goals.
Does my battery need to be VPP ready to get the rebate?
Yes. To qualify for the federal rebate, the battery must be capable of joining a Virtual Power Plant (VPP), which is a program where your energy retailer can draw on your stored power at peak times in exchange for payments or credits. You don’t have to join a VPP; the battery just has to be compatible. Every battery we install meets this requirement, and we can talk you through whether joining a VPP makes sense for your household.
Will a solar battery keep my power on in a blackout?
Only if it’s set up with backup capability, which not every battery includes by default. With backup, the battery keeps selected circuits running when the grid goes down, such as your fridge, lights, internet and some power points. How long it lasts depends on the battery size and what you’re running. We design the backup circuits around what matters most to your household and, where the system allows, set it up so your solar keeps recharging the battery during a daytime outage.
Are solar batteries safe for home use?
Yes, modern lithium-ion solar batteries are designed with advanced safety features such as thermal management and built-in protections against overcharging. When installed by qualified professionals, they provide a secure and reliable energy storage solution for your home.
Where is the best place to install a solar battery?
Solar batteries are typically installed in a garage, utility room, or another sheltered, well-ventilated area that stays dry. A professional installer will assess your property and recommend the safest and most efficient location.
How long does it take to install a solar battery?
Most solar battery installations can be completed within a day, depending on the complexity of the system and your existing setup. Your installer will handle all details to ensure a smooth and hassle-free process.
What kind of warranty do solar batteries come with?
Solar battery warranties typically range from 5 to 15 years, covering performance and defects. High-quality brands also guarantee a certain number of charge cycles or a minimum energy capacity over time, ensuring long-term reliability.
