Home solar battery systems

Jason Svarc


The huge leap forward in battery technology has seen an immense amount of interest in people looking to go off-grid, store their own solar energy (self-use) and become energy independent. Although the rapid pace of technology has resulted in some confusion over what is achievable and which system is best suited to an individual households. Here we help explain some of the advantages of home battery systems, provide some battery reviews and compare several of the leading battery systems.

For those new to solar see our basic introduction to the different solar system types including grid-tie, off-grid and hybrid battery systems.

Advantages of home battery systems

  • Reduce cost - Save money by using less energy from the grid

  • Reduce emissions - Reduce pollution from coal/nuclear/gas power generation

  • Be blackout safe - Have power available during a blackout or emergency

  • Become energy independent - Generate, store and use your own energy

Do you need a battery for your home?

For many people the cost of a battery system is simply too high, but this doesn't mean you can't take advantage of rooftop solar. For most households rooftop solar will reduce your electricity bills by 50% or much more depending on the amount of energy you use during the day as it is generated. For example it is possible to run energy intensive appliances such dishwashers, air-conditioners and washing machines for free using your solar energy during the day.

Many modern solar inverters have inbuilt ‘demand management’ controls which can automatically switch on ‘smart’ appliances when there is excess solar energy rather than sending it to the grid for little return. Also new generation AC batteries are now available such as the SonnenBatterie and Tesla Powerwall 2, plus an increasing number of grid-connect solar inverters are now 'battery ready' so it will be easy to add battery storage in the future.

How much does a home battery system cost?

The cost of home battery system depends on the size (capacity) of the battery and type of solar or hybrid inverter used. Typical household batteries can cost anywhere from $3500 up to $15,000 or more depending on the storage capacity measured in kWh (kilowatt hours). There are many different systems available which suit many different household energy needs. Here we have provided a guide as how much a typical battery systems will cost for a typical 3 bedroom home. See the home battery system price guide here

Popular battery options


DC coupled battery

The LG Chem RESU range of home battery systems are one of the most widely used and flexible battery options available being compatible with a huge range of the most popular home energy storage (hybrid) inverters and systems including the SolarEdge optimiser system. Available in two main sizes, 6.5kWh and 10kWh capacity, the RESU range is also one of the most affordable and reliable battery systems on the market.

Tesla Powerwall 2

AC battery

The Tesla Powerwall 2 is one of the most well known and most popular battery systems. Available in one size only the Powerwall 2 is an AC battery with a relatively large 13.5kWh capacity which is more than enough for the average household. The recent price rises bring it up to $10,500 plus installation so it is on the higher end of the price scale but is also offers some advanced features such as liquid cooling and inbuilt inverter/charger. However it still requires a solar inverter to operate with a solar array.

Home Solar Battery Comparison

Below is a table of the most popular and common battery systems currently used in Australia. Some of these can be retrofitted to existing solar installations such as the Tesla Powerwall 2, Sonnonbatterie and Enphase battery. There are also retrofit inverter options using the LG chem and BYD batteries. Ask your local licensed solar installer for more details and information.
