Use more of your solar
Daytime surplus and evening consumption reviewed to give the battery a practical role.
Home battery storage
Use more of your solar after the sun goes down.
Battery value depends on how much excess solar you have, when the home uses power and what you want protected during an outage. Laurence reviews those details before discussing size or equipment.

Care for your home
A battery needs a clear job to do.
The right design begins with the energy your solar leaves unused, the power your home needs after sunset and the circuits you would want during an outage. Laurence assesses those details before discussing capacity or equipment.
A useful first conversation
You do not need to diagnose it first.
These details help Laurence understand the job, ask the right questions and plan the most useful next step.
- 01Your current solar and inverter
- 02Evening energy use and tariff
- 03Backup, EV or expansion priorities
How Borda can help
Give the battery a clear job.
Capacity and power
Usable storage and output considered together so you understand how long energy may last and what can run at once.
Backup by design
Essential-circuit or broader backup expectations agreed before the electrical design is finalised.
Existing and future equipment
Solar compatibility, switchboard, phases, likely EV loads and possible expansion assessed as one system.
Safety first
Backup has limits
Stored energy and inverter output are different. Agree which circuits matter and what can run together before the system is designed.
→Start with the way your home uses power.
Tell Laurence what you want storage to achieve, what solar is already installed and which circuits matter most during an outage.
Useful to know
Storage, output and backup are separate decisions.
Clear practical information, supported by trusted Australian guidance where useful.
Capacity and power are different
Capacity in kilowatt-hours describes how much energy can be stored. Output in kilowatts limits how many and how large appliances can run at once. A bigger capacity number does not automatically mean stronger backup.
Australian Government · Batteries ↗Backup does not happen automatically
A battery must be specifically configured for outage operation. Depending on the design, it may support selected essential circuits, broader household loads within limits, or only one phase of a three-phase home.
Australian Government · Batteries ↗Where the battery goes matters
Safe clearances, wall construction, summer sun, weather, cable access and vehicle impact all influence the installation location. Future modules also need suitable space from the start.
SA Metropolitan Fire Service ↗The federal battery discount is not a flat figure
The Cheaper Home Batteries Program supports eligible systems, but the value depends on installation date and usable capacity. Rules changed from 1 May 2026, so Laurence confirms current eligibility rather than quoting a blanket percentage.
Australian Government · Cheaper Home Batteries ↗Direct with your electrician
The person discussing backup understands the circuits behind it.
Speak directly with Laurence about what matters during an outage and how the home uses energy after sunset. He checks the existing solar, inverter and switchboard, then explains the capacity, output and backup arrangement that best fit those priorities.
- You are heard.Talk through the job directly with Laurence.
- Your options are clear.Understand what matters now, what can wait and why.
- Your home is respected.The work is tested, explained and left tidy.
Compare battery pathways
Start with the right system architecture.
Explore two modular battery platforms, then talk with Laurence about which configuration—if either—fits your existing solar, energy use and backup priorities.
Straightforward from the start.
Explain the job once
Share what is happening, where you are and what a good result looks like.
Understand the recommendation
Laurence assesses the property, explains the options and confirms a clear scope.
Know what was completed
The agreed work is tested, left tidy and handed over with practical guidance.
Common questions
Before choosing a battery.
Helpful starting points. The right answer still depends on the property and the existing electrical setup.
Will a battery work with my existing solar?
Often, yes, but the inverter, system configuration, switchboard, phases and current product approvals still need checking. Laurence assesses the existing equipment before recommending the practical pathway.
Will it power my whole home during a blackout?
Only if the system is designed to do so, and always within its output and stored-energy limits. Many homes choose selected essential circuits; others require a broader design.
Can solar recharge the battery during an outage?
Some islandable systems can keep using solar and recharge the battery while the grid is down. Others can use only the energy already stored. This must be established during design.
How large should my battery be?
There is no universal size. Useful sizing considers daytime solar surplus, evening use, simultaneous appliance loads, backup priorities, tariff and future consumption.
Can I add more capacity later?
Possibly, if the product, final configuration, installation space and approval conditions allow it. Expansion should be discussed at the beginning rather than assumed.
Will a battery definitely save me money?
Not necessarily. Value depends on available solar surplus, when you use power, tariffs, feed-in rates, system cost and operating settings. Laurence will avoid generic savings claims.
Talk through the practical next step.
The right answer depends on the property and what is already installed.
