What’s the Best Solar Battery in Australia?

Fast read

In 2023 there is a wide range of products on the market available for all solar systems; below are the ones we recommend. The Tesla Powerwall 2 is advanced and efficient. It is known for its technology.

On the other hand, BYD batteries are affordable. Sonnen batteries, with their German heritage and Lithium-ion batteries, provide reliability and excellent customer service.

Sungrow Power Supply Co., Ltd. is another noteworthy option, specialising in solar inverters and energy storage systems.

Ultimately, choosing the right battery depends on factors such as energy requirements, budget, available space, and individual needs. Consult with solar and energy storage experts and stay informed about market trends and new technologies for best results.

Which are the best solar batteries in Australia?

For those who currently have solar in their homes or are thinking about installing solar in their homes, the question about batteries and whether or not you should get batteries has more than likely come into your mind. Australia has different types of solar batteries. The best solar battery for you depends on what you need and like.

How do you choose?

With so many options, how do you choose the best solar battery for your solar system? A few different variables need to be considered when choosing a specific solar battery for yourself. The main things to consider are:

  • Battery capacity – get enough for your family now and in the future. EV charging will add to the capacity need;
  • Price – do not go for a price-alone decision, so cheap is not an option; go for a solution that offers value;
  • Power rating – A solar battery’s power rating refers to the maximum amount of power it can deliver at a given time. Typically measured in kilowatts (kW). Power rating is important as it shows how much electricity a battery can handle. A higher power rating means the battery can supply more energy simultaneously to power various devices in your home.
  • Depth of discharge – how far can you recycle the battery as recommended by the battery manufacturer? If there are two batteries and one has a 90% recommended discharge, you can pull 9 kW of power out of it, but if the competitor model only has an 80% recommended discharge, from full to empty, you will only get 8 kW. An important consideration during a blackout.

More considerations

  • Warranty – battery warranties can be confusing, so make sure you check out the various offers and compare apples with apples. Of course, a product warranty is only as strong as the company that backs it.
  • Backup capabilities – Interestingly, not all solar batteries have a backup power capability. Many homeowners assume all batteries have a backup capability, as that’s one of the key battery advantages. So make sure you understand what your favourite model offers in case of a blackout.
  • A good monitoring app is essential for easy control and optimization, compared to a difficult-to-understand solution. Ask your installer to demonstrate the monitor app of their recommended solution(s).

Tesla – a great overall option

The Tesla Powerwall 2. Yes, that is right, Tesla is not only one of the leading electric car companies in the world, but they are also in the energy storage industry. Their battery is one of the most efficient and advanced on the market today.

Their battery packs use advanced lithium-ion technology for reliable performance and efficiency.

Although it has a slightly higher price tag than competitor models, it has an impressive capacity of 13.5kWh, which for the average home, will power the house through the night and enable the home to be almost self-sufficient. With 13.5 kWh, the unit has more capacity than some of the competing batteries.

The technology includes a battery and inverter, allowing solar panels to power home electricity needs at the same time. The Powerwall has the potential to be installed with any new or existing solar system.
