Keep Your Power Working After Dark

A grid outage, a scorching summer night, or simply watching your feed-in credit shrink each quarter, these are the moments a solar battery earns its keep. Rapidcool Air Conditioning, Electrical & Solar designs and installs solar batteries across the Illawarra, sized to match how each household or business actually uses power.


Without storage, a solar system only works while the sun is up, and any energy you don't use straight away is exported back to the grid for a modest credit. A battery keeps that power on hand instead, ready for the evening rush, an overnight air conditioning run, or an unplanned blackout, so the energy you've already generated works harder for you.


Ready to stop losing power back to the grid? Call 02 4283 1077 to arrange a battery system built around your Illawarra property.

Power That Pays For Itself

Watch Your Bills Shrink

A System Built Around You
Every battery Rapidcool installs is sized and configured for the property it's going into, not fitted from a standard template. Existing solar arrays, daily energy habits, and future plans, whether that's an EV, a pool, or simply more backup capacity, all factor into the setup, so the system actually matches how a household or business uses power.


Less Grid, More Independence
The better matched the battery, the less a property needs to lean on the grid. That means steadier protection against rising electricity costs and a stronger buffer during outages. Many customers find their day-to-day habits shift naturally over time to make the most of the power their system produces, without any real effort involved.


Track It in Real Time
Every installation comes with a monitoring app matched to the battery and inverter brand, whether that's Sigenergy, GoodWe, FoxESS, or Sungrow. It gives a live view of solar generation, household consumption, battery charge, and grid usage, so it's easy to see exactly where the savings are coming from.


Support That Doesn't Stop at Installation
Rapidcool remains available well after the job is finished. Whether it's a question about how the system's performing or help getting more out of the monitoring app, ongoing support across the Illawarra is part of the package.

Frequently Asked Questions

  • How much maintenance does a solar battery need?

    Solar batteries generally require very little ongoing maintenance. Most modern systems are designed to run with minimal intervention, needing only occasional visual checks and monitoring through the accompanying app. Keeping the unit clear of dust and debris, and ensuring adequate ventilation around it, helps maintain performance. Any servicing needs are typically outlined in the manufacturer warranty and specific to the battery chemistry used.

  • Are solar batteries safe to install near a home?

    Solar batteries are designed and tested to meet strict Australian safety standards before being approved for sale. Installation location matters, with placement guidelines around ventilation, temperature and proximity to living areas factored into every setup. When installed by a licensed, accredited electrician in line with these standards, solar batteries are considered a safe addition to a property.

  • What is the difference between AC and DC coupled batteries?

    AC coupled batteries connect to the existing solar inverter and convert power separately, making them well suited to retrofitting onto an established solar system. DC coupled batteries connect directly to the solar panels through a hybrid inverter, generally offering slightly higher efficiency but often requiring installation alongside a new system. The right choice usually depends on whether solar is already installed.

★★★★★ ★★★★★

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.
