Get More Out of the Solar You Already Have

Without a battery, the solar you generate during the day and do not use is exported to the grid for a small feed-in tariff, then you buy it back at full price after dark. A battery closes that gap: you store your cheap daytime generation and run your home on it through the expensive evening peak.

We install solar batteries across Brisbane, Ipswich and Logan, on new systems and as a retrofit to solar you already have. Tesla Powerwall and other quality batteries, sized to your usage, with proper backup wiring so the essentials keep running when the grid goes down.

Is a Battery Worth It?

The honest answer is: it depends on your usage. A battery makes the most sense if you use a lot of power in the evenings, have a decent-sized solar system generating surplus during the day, or you value backup through Brisbane's storm-season outages. If your usage is mostly daytime and your solar already covers it, the case is weaker.

We would rather tell you that up front than sell you a battery that never pays for itself. Send us a bill and your solar setup and we will give you a straight assessment, the right size if it makes sense, and a fixed price with any current incentives applied.

A complete, safe, backup-capable system.

  • Safe isolation and compliance to standard

How Battery Backup Works in a Blackout

Not every battery keeps your home running in an outage: it depends on the backup wiring. Set up properly:

  • When the grid drops, the battery automatically keeps your nominated essential circuits running (lights, fridge, internet, a power point or two)
  • Your solar can keep charging the battery during the outage, extending how long you last
  • You choose which circuits are backed up, sized to the battery

In a suburb that loses power in every big storm, that is often the feature people value most. Pair it with a solar system or retrofit it to what you already have.

How It Works

1

Send your details

A recent bill and your solar setup let us size a battery and give honest advice on whether it stacks up.

2

Battery, backup wiring, isolation and metering all handled in-house by licensed electricians.

3

Storing and backed up

Commissioned and monitored, so you run on your own power at night and stay on in a blackout.

Frequently Asked Questions

Can't find your answer? Call 07 3813 0067 and we will happily talk it through.

Can I add a battery to my existing solar?
Yes. Retrofitting a battery to an existing solar system is one of our most common jobs. We check your setup and add storage sized to your evening usage.
Is a solar battery worth it?
It depends on your usage. Batteries pay off best if you use a lot of power in the evenings, generate surplus solar during the day, or value blackout backup. We will give you a straight assessment rather than overselling.
Will a battery keep my power on in a blackout?
With the right backup wiring, yes. Your nominated essential circuits keep running, and your solar can keep charging the battery during the outage. It is a popular feature in storm-prone suburbs.
Which batteries do you install?
Tesla Powerwall and other quality batteries with real warranties. We will recommend what suits your system, usage and budget.
How big a battery do I need?
Enough to cover your evening usage without overspending. We size it from your bill and solar output rather than selling you the biggest unit.
Are there rebates for batteries?
Incentives change over time. We will confirm any current battery incentives that apply to your install and factor them into your quote.
