Which home battery is right for me

Which home battery is right for me?

Every day, more and more Australians are adding home battery storage to their solar power systems. The motive behind this is to store electricity generated by their solar panels for use later on. But with so many home batteries on the market, choosing the right option for you can be a challenge.

What is Battery Storage?

In most Australian homes, a large proportion of the energy produced by solar power panels is sent back to the grid because it’s generated when it’s not needed, i.e. the middle of the day. However, adding home battery storage to a new or existing solar power system allows you to store your unused energy to use: 

  • At night
  • On low sunlight days
  • When utility rates are more expensive
  • During blackouts

Battery storage is a smart way to offset your electricity costs as you maximise your solar energy usage and minimise your reliance on the grid.

Key Considerations

There are a few key things to consider if you are looking for a battery for your home.

  1. How much power do you currently use on average per day? Also, does your household generally use the most energy at night? It is important to have an idea of the capacity (kWh) you need in your battery. Note: You can refer to your power bill to see how much power is used.
  2. Is your family still growing? You will need a system that can accommodate your changing needs.
  3. Maximum Depth of Discharge (DoD): This indicates the percentage of the battery that can been discharged relative to the overall capacity of the battery. For example, if a 6 kWh battery has a 90% maximum DoD, then you shouldn’t use more than 5.4 kWh before recharging the battery. Otherwise, its lifetime may be compromised.
  4. Warranty Make sure you choose a provider that has longevity and a good reputation.
  5. Budget: How much are you looking to spend upfront?

Two main types of Battery Storage Solutions

What you will also need to consider is the type of battery storage solution. Below is an overview, which will give insight into the key differences between the two different popular solutions:

  • Lithium-ion: Currently, the most popular option for solar systems. Lithium-ion batteries are typically lighter and have a higher maximum DoD than other solutions, typically around 90%. The majority of new battery technologies use some form of lithium-ion composition, but they are more expensive than lead-acid.
  • Lead-acid: batteries are often used in off-grid situations with much shorter lifetime and a lower maximum DoD.

Solahart is home to a great range of lithium-ion batteries.


Featuring more than twice the usable energy storage capacity (13.5 kWh) of the original Tesla Powerwall 1, Tesla Powerwall is a compact, scalable battery with a built-in inverter that’s simple to install and looks great on any wall. Tesla Powerwall can be either floor mounted or wall mounted.

Is Tesla Powerwall 2 right for you?

  • Lithium-ion battery pack that stores energy from your PV system in off-peak times.
  • Easy to install, completely automated and requires no maintenance to make your life easier.
  • Higher energy density offers reduced footprint, making it a nice, aesthetically-pleasing addition to your home.
  • Can be added onto any existing PV system.
  • Offers emergency backup power to your essential loads.
  • Expandable to up to 10 x Powerwall batteries across 3 phases.

Solahart PowerStore

Solahart PowerStore is Australia’s first solar-smart electric water heater. Together with a power meter/Gateway, it captures the excess energy from your rooftop solar panels and uses it to heat your water gradually, for use at a later time.

Like a battery, it stores energy (in the form of hot water), only it’s a lot more affordable.

Is Solahart PowerStore right for you?

  • Use your excess solar power to heat your water, instead of sending it back to the grid.
  • Works with both new and existing solar power systems.
  • Ensures you have a reliable supply of hot water by drawing the minimum power from the grid that is necessary.

Solahart Solar-Ready water heater is a smart choice because it provides an immediate solution to your hot water needs right now and also gives you the flexibility to upgrade and save on your energy costs in the future.

Whether you need a simple solution to get back into hot water quickly, a solar water heater from day one, or the option to upgrade to energy-saving solar in the future, you’re in control.

And no matter which option you choose, enjoy the extra peace of mind with a 10-year cylinder warranty.


1: Solahart Warranty Details: 10/3/2 warranty; 10 year cylinder and collector supply, 3 year cylinder and collector labour, 2 year parts supply including labour; applies to a single family domestic dwelling only. All other applications have a 3/1/1/1 warranty; 3 year cylinder and collector supply, 1 year parts supply, 1 year labour.

2: Energy savings of up to 65% shown is based on Australian Government approved TRNSYS simulation modelling of a Solahart 302L and using a medium load in Zone 3 and apply when replacing an electric water heater. Any savings will vary depending upon your location, type of Solahart system installed, orientation and inclination of the solar collectors, type of water heater being replaced, hot water consumption and fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff. Refer to solahart.com.au for further information.

3: For a Solahart Solar Hot Water system, each STC represents 1 megawatt-hour (MWh) of electricity displaced over a 10 year period. The number of STC’s which may be created for the installation of an eligible solar water heater varies with the size and model of the solar water heater and the region (or zone) in which the unit is installed. The value of an STC is not fixed and varies depending on market factors.
