Back to sunnier days.
now makes its own battery, and this install is built around it.

The inverter, smart meter and battery are all Fronius, so they’re designed to work together. The meter shows what the solar is producing and what the house is using.

What went in:

36x SunPower 455W panels (30 year product, 30 year performance warranty)
1x Fronius Gen24 Symo PLUS SC 12kW inverter (10 year warranty)
1x Fronius Smart Meter
1x Fronius Reserva BCU
5x Fronius Reserva 3.15kW modules

The last gas appliance in this house is gone.

These owners wanted to go fully electric. Better savings, and a home set up properly for the long run.
It wasn’t a simple job. Everything had to go in the basement, and the conduits couldn’t be hidden in the walls. Leaving them exposed would have looked messy, so the team ran a cable tray to keep it all neat. Swipe through to see how it came out.

The 30kW Sigenergy controller gives the home whole-home backup. If the grid drops out, the house keeps running.
The old gas hot water system was the last gas appliance on the property. The new heat pump handles hot water on electricity, which means it can run off the solar and the battery instead of the gas network.

Estimated annual saving from taking the home all electric: $4,859.
The owners also had $9,555 taken off the upfront cost through the federal STC incentive and the Cheaper Home Batteries Program.

What went in:
39x Aiko A490-MCE54Mb 490W panels (25 year product, 30 year performance warranty) 1x SigenStor EC 30.0 TP 30kW inverter (10 year warranty) 4x SigenStor BAT 9.0 batteries (three-phase) 1x Sigenergy Gateway with backup 1x Reclaim ECO 300 litre heat pump

Sam and Tas have just knocked over their CPD training for the year.

To keep our solar accreditation current, every accredited installer has to rack up 100 CPD points annually - new standards, new technology, changes to how things get done on the tools.

Good to be back at school fellas; just like the little apprentices 🤓 🧑‍🎓

We installed this client’s solar system back in 2023. A Powerwall 2 followed in 2024. This year, we’ve added a Powerwall 3.

Same home, same family, three years of careful expansion.�

For anyone holding a Powerwall 2 and wondering if it’s time to upgrade — you don’t need to replace it. Tesla have (finally) made the PW2 and PW3 fully compatible. We fitted a Tesla Energy Meter to enable that compatibility, and the two units now run as one system.�

This is the value of designing for the long term from the outset. Household energy needs change. Usage patterns shift, an EV gets added, priorities move. A properly specified system should accommodate that evolution without requiring you to start again.
If you’re running a Powerwall 2 and want to understand your options to add more battery storage, we’re happy to talk it through.

Set among tall trees, this home had partial shading to work around. Rather than a standard flush mount, we angled the panels specifically to maximise production despite the shade line. Same roof, different thinking.
For this one:
⚡ 14.7kW System Size
⚡ 19,062kWh Estimated Annual Solar Generation
⚡ $2,969 Estimated Annual Energy Bill Savings

How we did it:
30 panels, 25-year warranty
⚡ Sigenergy SigenStor Bat 10.0 x3
⚡ Gateway with backup (single phase)
⚡ Switchboard upgraded to RCBOs
⚡ Sigenergy 7kW EV charger, single phase

With the battery running, this place can go through the night — or a blackout — without the lights flickering. And when the 3-hour free power window kicks in, they can use it for EV charging, topping up the battery, whatever they please.

Got a shaded roof and figured solar's not really worth it? Might be worth a second look. It just needs to be designed properly, not slapped on.

Bigger battery, bigger savings?

Not necessarily.

It's one of the most common assumptions we walk people through before they commit to anything.

Battery size should match how your household actually uses power, not how big your solar system is. Get that wrong and you're either paying for storage you'll never touch, or still buying grid power on cloudy days.

Here's the bit most people don't know: batteries like the Sigenergy SigenStor is modular. That means we can size it around your actual usage now, and add capacity later if your needs change. We're all about Future Proofing your home.

For these installs, we looked at the customer's export data and usage before landing on the right size.

Two recent installs, two different system sizes, both with the same focus on getting the most out of the available roof space.

Aiko panels paired with Sigenergy inverters, with the larger system installed on a tilt to optimise solar production at their location.

It’s the little details in the design and installation that make the difference.

A different approach, and one that made sense for this home.

With an existing 6kW solar system already in place, the owners chose to add battery storage instead of more panels. Having recently bought a hybrid car and with an EV charger on the radar, it was all about planning ahead.

By pairing their new Sigenergy battery with OVO's 11am to 2pm free power window, they've added more flexibility while future-proofing the home for what's next.

From pre-wire to finished install. 👌

We first visited this Sorrento build back in February to get all the cabling hidden away before the walls went up. Fast forward to this week, and the system is complete.

Always a good time working alongside the team at .

Planning a new build? Get in touch early so we can help future-proof it from day one.
