SAA S6093214
MEA member 23598 · QLD licence 92489

New solar and battery systems across the Sunshine Coast and Brisbane, designed and installed by the SAA accredited contractor and signed off by a licensed Queensland electrician. We size the battery to your evenings, not to the biggest stack a rebate allows, and we handle the rebate paperwork, the grid connection and any switchboard work.
Systems we install
Start with what matters to you. The brand is the answer, not the question.
Power through a blackout
Our pick
Inverter, battery and backup switching in one prewired cabinet, with whole home backup available and a fast switchover when the grid drops. Whole home backup depends on your switchboard, so we quote it per site.
Biggest savings
Our pick
Sizing matters more than the brand. We size the battery to your evenings, not the biggest stack a rebate allows. The Fox ESS CQ7 stacks in 6.96kWh modules, so it can match your usage closely.
Try the solar calculatorThe best app, and ready for an EV
Our pick
The tech lover's pick: a five in one stack with an AI driven app, and an optional DC module that charges an EV straight from your solar and battery.
A tight budget
Our picks
Fox ESS is the one we install most: proven hardware and everyday value. Sungrow is the other proven workhorse. Either one goes with any of the three panels we install.
Compare the three panelsKeep the solar you already have
Our pick
The retrofit specialist: an AC coupled option keeps a good existing solar inverter on the wall, with unlimited cycles for everyday use under SolaX's Australian warranty terms.
How adding a battery worksA three phase home
Our picks
Up to 29.9kW of three phase solar and battery, the biggest system an ordinary connection takes. Fox ESS, GoodWe and Sigenergy at 29.9kW, Sungrow at 25kW.
Compare the three phase systems
Packages come with Trina Vertex S+ panels as standard, or Tindo, made in Australia, or Aiko, for a roof with shade on it. We confirm the final design from your photos, or at a design visit if one is needed.
The biggest systems your connection allows
Energex and Ergon both allow up to 30kW of inverter on a three phase connection, so three of these are built right under that line at 29.9kW. Each one carries a full battery stack, from 40kWh to 54kWh, and every figure on their pages comes off the manufacturer's own datasheet.
One tower on the wall: 29.9kW of three phase hybrid inverter and a full 49.9kWh battery column, prewired.

Both rebates, applied in your quote
Solar: the STC rebate
Small scale Technology Certificates take money off a new solar system. The value depends on the system size, your zone and the certificate price, and it steps down each year. It is set on the date the system is installed and commissioned.
Batteries: Cheaper Home Batteries
The federal program takes money off a new home battery, based on its usable capacity. The installer must hold SAA battery accreditation, a separate class to solar. We hold both (S6093214) and install to AS/NZS 5139.
We check eligibility before we quote, and both rebates come off the price in your written quote. A bigger battery than your evenings need rarely pays back faster: it just costs more.
Whole Home Backup vs Essential Circuits
Battery “backup” means different things depending on how it’s wired. We explain the tradeoffs before you commit to a system.
Whole home backup
Runs your entire switchboard during a grid outage. Depends on inverter continuous output, switchboard condition, load management and correct changeover setup. Best suited to homes with manageable peak loads or smart load control.
- • Larger inverter / battery capacity required
- • Switchboard typically needs upgrading
- • Load shedding or smart circuits often needed
- • Higher upfront cost, fuller blackout coverage
Essential circuit backup
Runs only nominated circuits (fridge, lights, internet, comms) during an outage. Usually simpler and cheaper to retrofit, with a dedicated backup subboard that isolates protected circuits from the rest of the house.
- • Smaller inverter / battery sufficient
- • Backup subboard added to switchboard
- • Aircon, oven, EV charging typically excluded
- • Lower cost, targeted resilience
Honest Reviews of the Batteries We Fit
Written after carrying them up the driveway, not from a spec sheet. Each one compares usable capacity rather than nominal, says where the battery suits a Queensland home and where it does not, and covers the backup and registration details a brochure leaves out.

A Solar & Battery Install Is Only as Good as the Switchboard Behind It
Blackout backup is the part that depends on your switchboard. Every circuit the battery backs up during an outage must have a Type A RCBO, so whole home backup means the whole board, while essential circuit backup means only those circuits. Add spare capacity for the new isolators, compliant labelling and correct backup circuit separation, and we assess all of it before quoting so the system is safe, compliant and practical, not patched in on top of an old board that won't handle it.
If your switchboard is undersized, has ceramic fuses, or needs Type A RCBOs for the backup you have chosen, we'll flag it during the quote and price the upgrade up front. No surprise variations on install day.
What we check before quoting
- →Main switch and busbar rating vs total load + new battery/inverter draw
- →Type A RCBO protection on every circuit the battery will back up in a blackout, per AS/NZS 4777.1 and AS/NZS 3000
- →Space for solar isolators, battery isolators and labelling
- →Backup circuit separation: what runs during a grid outage and what doesn't
- →Earthing and bonding compliance with current standards
- →Compliant labelling and shutdown procedure documentation

Solar and Battery Questions
Straight answers on rebates, battery backup, switchboards and coastal installs, from the contractor doing the work.
Do I still get a rebate on solar and batteries?
Yes, both are still available. New solar systems are discounted up front through the Small scale Technology Certificate (STC) scheme, and new home batteries are discounted through the federal Cheaper Home Batteries Program. The exact amount depends on system size, your zone, usable battery capacity and the current certificate price, and the solar STC value reduces each year. The value is set when your system is installed and commissioned, not when it is quoted, so having the system installed before the next step down is what keeps the higher value. We handle all the rebate paperwork.
Do I need a battery, or is solar on its own enough?
Solar on its own still cuts your daytime power bills and is the cheaper place to start. A battery adds value if you use a lot of power in the evening or want backup during outages, by storing your excess daytime generation instead of exporting it cheaply. We size the system to your real usage and tell you honestly whether a battery pays its way for your household, rather than just selling you the biggest one the rebate allows.
Will my battery keep the power on during a blackout?
Only if the system is set up for backup, and how much it runs depends on how it is wired. Whole home backup runs your entire switchboard but needs a larger inverter and battery and usually a switchboard upgrade. Essential circuit backup is simpler and cheaper and runs only nominated circuits like the fridge, lights and internet, with aircon, oven and EV charging typically left off. We explain both tradeoffs before you commit, because not every solar or battery system includes blackout backup by default.
Does my switchboard need upgrading for solar and battery?
Not automatically, and we confirm it before quoting rather than on install day. A battery that simply stores your solar and offsets your bills needs no safety switch upgrade, whatever your existing board has. Two things do trigger board work. The first is blackout backup: when the battery runs your home during an outage it becomes the supply for those circuits, so every circuit it backs up must have a Type A RCBO. Whole home backup means the whole board, essential circuit backup means only those circuits. The second is the board itself, such as ceramic fuses, an undersized main switch, or no spare space for the new isolators and protection. We check both, and price any upgrade up front so there are no surprise variations once we start.
How long does a solar and battery installation take?
A typical home solar install is completed in a single day. Adding a battery or any switchboard upgrade can extend that, and we confirm the timeframe in your quote before we begin. After the install we handle the grid connection paperwork and approvals, so the only thing you do is switch it on.
Are solar panels and batteries suitable for coastal Caloundra homes?
Yes, and the salt air on the Sunshine Coast is exactly why component choice and mounting matter. Coastal and marine conditions are harder on rooftop fixings, isolators and enclosures, so we select tier 1 panels and corrosion rated mounting suited to your site and install to current standards. Being based on the Sunshine Coast means we know how these systems hold up here and we back the workmanship for the full warranty.
Can I add an EV charger to my solar and battery system?
Yes, and doing it at the same time is the most cost effective approach. One switchboard assessment and one visit covers both, and a solar aware charger can top up your car from excess daytime generation instead of the grid. You can see the full detail on our EV charger installation page.
Can I finance a solar and battery system?
Yes, we offer finance through the Brighte Green Loan, so you can spread the cost rather than pay it all up front. Brighte's published figures are a 7 year term from 9.49% p.a. (comparison rate 10.98% p.a.). You can also apply directly for a bank green loan, such as Bendigo Bank's Unsecured Green Personal Loan, or ask your own bank. We take nothing from any lender, and your price is the same however you pay.
