Reliable Solar Batteries in Wollongong

Store the Sun's Power

With electricity prices continuing to climb, more homes and businesses are pairing batteries with existing or new solar to cut their reliance on the grid altogether. Sized to suit your household's needs, Rapidcool Air Conditioning, Electrical & Solar supplies and installs solar batteries in Wollongong homes and businesses. 


Most homes with solar only use a fraction of the power their panels produce during the day, sending the rest back to the grid for a feed-in credit that's often worth a fraction of what you paid for it. Solar batteries change that equation by storing what you don't use on the spot, so it's there for the evening peak, an overnight run of the air conditioner, or a grid outage that would otherwise leave you without power.


When you’re ready for round-the-clock savings on your solar, call our team on 02 4283 1077 to explore which solar batteries are right for your property and  we can help with solar panel installations too.

Savings You Can See

Save Money, Save the Planet

Maximise energy savings
Solar batteries help you get more value from every dollar you've already invested in solar. Every Rapidcool battery installation includes access to a monitoring app matched to your battery and inverter brand, whether that's Sigenergy, GoodWe, FoxESS, or Sungrow, so you can track solar generation, household consumption, battery charge, and grid usage in real time. Shifting high-energy tasks like washing, dishwashing, or EV charging into daylight hours means you're using stored solar power rather than paying full retail rates from the grid.

Custom designed systems
No two properties use power in the same way, so we size and configure every battery system around your household or business, not a one-size-fits-all setup. We take into account your existing solar array, daily usage patterns, and future plans, whether that's an EV, a pool, or simply wanting more backup capacity.

Energy independence
A well-sized battery reduces how often you need to rely on the grid, giving you more control over rising electricity costs and better protection during outages. Over time, many customers find their habits naturally shift to make the most of the power they generate, without needing to think about it.

Ongoing local support
Our team doesn't disappear after installation. If you have questions about how your system is performing or want help getting more from the monitoring app, Rapidcool Air Conditioning, Electrical & Solar is on hand to support you long after the job is done.

Frequently Asked Questions

  • How long do solar batteries last?

    Most solar batteries are designed to last between 10 and 15 years, though this varies by brand and how the system is used. Manufacturer warranties typically reflect this expected lifespan, giving a clear indication of what to expect from the investment.

  • Can a solar battery run my whole house during a blackout?

    This depends on the size of the battery and how much power the home uses. Some systems are set up to keep essential circuits running during an outage, while larger systems can cover more of the household.

  • Do I need approval to install a solar battery in NSW?

    Grid-connected battery installations in NSW need to meet Australian and NSW electrical safety standards, and installation should be carried out by a Clean Energy Council accredited installer to ensure compliance.

  • Can I add a battery to my existing solar system?

    In most cases, yes. Batteries can generally be retrofitted to an existing solar system, though compatibility depends on the current inverter and setup, so an assessment is recommended beforehand.

  • How do I know what size battery I need?

    The right size depends on household energy use, the size of the existing solar system, and whether the priority is backup power, daily savings, or both. These factors should all be considered when choosing a system.

★★★★★ ★★★★★

Absolutely amazing business, the customer team is really friendly. Just had a second air conditioner unit installed with them. The first one installed around a year ago has been working amazingly and is super energy efficient. Installation was really quick, Jordan was really professional and made sure everything was okay prior to turning off the power. Work space was left tidy and the indoor and outdoor unit are perfectly placed. Will always recommend them to any local looking for a quality air conditioning team.

Had two 7.1kW Panasonic air conditioners installed and couldn't be happier with the experience. Communication from start to finish was excellent — clear, prompt, and professional. The pricing was very competitive, and the quality of the workmanship really stood out. Every detail of the installation was handled with care, and the team made sure everything was neat, efficient, and working perfectly. Highly recommend for anyone looking for reliable service and top-notch attention to detail.

Highly recommend. We had the Advantage Air system installed in 2024 with each zone on their own sensor, so each room can be at their chosen temp. Fast and easy install process, outstanding very informative sales and technician staff. Had the system serviced last week — very reasonable pricing for service. It is the best investment we've ever made, the whole family absolutely loves this system. Highly recommend this local company.
