Keep your solar for the evening peak
A battery moves your own generation into the hours you actually use it, instead of exporting it when the buyback rate is at its lowest.
How it works
A home battery is a buffer between what your roof makes and when your household needs it.
It charges from your surplus
Once the house has taken what it needs, the excess charges the battery rather than being exported. Charging happens through the middle of the day when generation is highest.
It discharges when you get home
From late afternoon, the household draws from the battery instead of the grid. This is the window where cooking, cooling and lighting all stack up at once.
The grid covers what is left
If the battery empties overnight, supply reverts to the grid without you doing anything. Some setups can also charge from the grid on a cheaper tariff, if the tariff structure warrants it.
Backup runs a nominated circuit
If a backup circuit is fitted, selected loads keep running during an outage. This is a specific piece of wiring work, not something every battery does by default, and it is agreed before installation rather than assumed.
Why this matters in Perth
The WA energy market and the local climate both change what makes sense here.
The WA buyback structure rewards shifting, not exporting
Because daytime export earns the lower rate under the Distributed Energy Buyback Scheme, power you store and use yourself in the evening avoids buying at the retail rate. Storage in WA is mostly an argument about self-consumption rather than about selling more.
Your evening peak is the expensive part of the day
In most Perth households the load between late afternoon and bedtime is the block solar cannot reach on its own. That gap is the specific thing a battery is for, and it is the number worth looking at before choosing a size.
Blackout behaviour, described honestly
A battery without a backup circuit will shut down in an outage along with the rest of the system, for the safety of anyone working on the network. If keeping the fridge and some lights running matters to you, say so early, because it changes the install.
You do not have to do it all at once
A solar system specified as battery ready leaves the right inverter and the right space in place, so storage can be added later without paying twice for the same work.
System options
Choosing a specification
Battery sizing follows your evening consumption and how much surplus your roof actually produces. Oversizing storage is an expensive way to buy capacity you never cycle.
Evening cover
Sized to carry the after-work peak on a typical day.
Full evening and overnight
For households that want to stay off the grid from sunset to sunrise.
Storage with backup
Adds a nominated backup circuit for outages.
Paying for it
Cash, finance and lease arrangements are all available. Terms, rates and approval conditions come from the finance provider, not from us, so we set them out plainly rather than quoting a headline figure.

Common questions
Home Battery Storage questions
Will a battery keep my house running in a blackout?
Only if it is installed with a backup circuit, and only for the loads on that circuit. Without one, the system disconnects during an outage so that nobody working on the network is exposed to power from your roof. Tell us early if outage cover is a priority.
Can I add a battery to solar I already have?
Usually. It depends on your existing inverter: some can be paired with a battery directly, others need an additional unit or a hybrid replacement. We check what you have before quoting rather than assuming a retrofit is straightforward.
How long does a home battery last?
Batteries are warranted on a combination of years and energy throughput, so how hard you cycle it matters as much as its age.
How do I know what size to get?
Start with how much power the household uses after sunset, then look at how much surplus your roof genuinely produces to charge it. A battery bigger than your daily surplus will not fill, and one smaller than your evening load will not carry you through it.
Is a battery worth it in Perth?
It depends on your evening consumption, your current export rate and what you pay to buy power back. That is a calculation on your numbers, not a general answer, and we would rather run it with you than give you a slogan.
Where does the battery physically go?
Most units are wall mounted in a garage or on a shaded external wall, with clearance requirements and temperature limits set by the manufacturer. Perth summer heat is a real consideration, so placement gets checked on site.
