Fronius installers Brisbane.
Mission Green installs and services Fronius string and hybrid inverters across Brisbane and South East Queensland, and designs battery retrofits around existing Fronius systems. Brisbane's 5.2 peak sun hours a day suit a well-designed Fronius array; whether to pair a battery, retrofit, or choose a different inverter entirely is decided from your actual setup at a free assessment.
We don't only install Fronius. So this isn't a sales pitch.
Fronius is a premium Austrian string and hybrid inverter brand, and one of our top choices for simple, unshaded roofs. But we install other inverter brands too — so when we recommend a Fronius, it's because it fits your Brisbane roof, not because it's the only thing on the shelf. Start with the full Fronius overview if you're earlier in your research.
Sometimes the honest answer is a different inverter
A Fronius string inverter is a strong pick for a simple, unshaded Brisbane roof. But if your roof has heavy shading, awkward orientations, or you want a specific all-in-one battery ecosystem, another inverter — or microinverters — can be the better design. We'll tell you that before you pay a deposit, even if it means we quote you something other than the brand you searched for.
What we actually do with Fronius
We install and service Fronius inverters and design battery retrofits around them: new solar systems built on a Fronius string or hybrid inverter, health checks and fault diagnosis on existing Fronius systems — including ones we didn't install — and battery additions that work with the Fronius you already own rather than forcing a replacement you don't need.
Bring us the other quotes
Shortlisting Fronius against Sungrow, GoodWe or an all-in-one battery system? Good — you should. Bring your other Brisbane quotes and we'll walk them line by line: what's genuinely different, where a rival wins, and whether the Fronius premium is justified for your home. Sometimes the honest answer is the cheaper inverter — and we've written the guides that say so.
One installer, whichever brand you pick
Mission Green designs, installs and commissions your system and coordinates any manufacturer warranty claim on your behalf, so you're never bounced between the maker and a subcontractor. That applies whether you land on a Fronius or one of the other brands we carry.
MG coordinates the manufacturer warranty and handles claims on your behalf; it does not replace or extend the manufacturer's warranty. Your Australian Consumer Law rights apply in addition.Brisbane sun is the easy part.
The tariff maths is the real story.
South East Queensland generates a lot of solar — and pays little for exports. That combination shapes what an honest Fronius design looks like here: strong generation, high self-consumption, and a serious look at storage.
5.2 peak sun hours/day
Brisbane averages 5.2 peak sun hours per day — well above the southern capitals. A correctly sized system on an unshaded roof generates strongly year-round, which is exactly the simple-roof scenario where a Fronius string inverter is one of our top choices.
Source: our rebate & tariff checker, as at 2 July 2026.~33c/kWh average tariff
The average usage tariff in the Energex network area — which covers Brisbane — sits around 33c/kWh. Every kilowatt-hour your Fronius system lets you use from your own roof instead of the grid avoids that charge, which is where most of the value lives.
Energex area; Canstar/QCA, as at June 2026. Indicative — your plan may differ.Typical payback 4–6 years
With strong sun and high tariffs, a well-designed Brisbane solar system typically pays for itself in 4–6 years. That's indicative only — actual payback depends on your usage, tariff, system size and how much generation you use yourself rather than export.

SEQ feed-in tariffs are low, so storing your excess solar instead of exporting it is worth a serious look. There are two main paths — and which one fits depends on the Fronius you own, not on what a salesperson wants to sell.
DC-coupled: hybrid Fronius + battery
If you have a compatible Fronius hybrid inverter, a modular battery such as the BYD Battery-Box HVM can pair with it directly — the same pairing BYD supports with compatible hybrids from Fronius, GoodWe or SMA. You keep the inverter you own and add storage behind it.
BYD Battery-Box →AC-coupled: battery alongside your Fronius
If your Fronius is a string inverter with no battery port, an AC-coupled battery — such as a Tesla Powerwall 3 — can sit alongside it. Your Fronius keeps doing its job on the solar side while the battery handles storage independently. No inverter replacement required.
Powerwall 3 →New system: Fronius from day one
Building new? For a simple, unshaded Brisbane roof, a Fronius string or hybrid inverter is one of our top choices, and a hybrid model keeps a clean battery path open for later. We design the system around your roof, phase and Energex connection — not around a brand quota.
Get a Design →| A battery retrofit is usually worth it if… | Consider something else if… |
|---|---|
| Your Fronius is a compatible hybrid — a DC-coupled battery like the BYD Battery-Box HVM pairs with it directly. | Your Fronius is an older string-only model — an AC-coupled battery alongside it, or a hybrid upgrade, may be the cleaner design. |
| You're on a low SEQ feed-in tariff (typically 3–10c) and exporting most of what you generate. | You already use most of your solar in daylight — there's less excess for a battery to capture. |
| Your inverter is healthy with years left in it — retrofitting around it beats replacing it. | Your inverter is near end of life or faulting — replacing it with a hybrid may beat building around it. |
| Your evening usage is high — stored solar displaces the ~33c/kWh you'd otherwise buy back. | Your usage is already very low, or you're moving soon — you may not recoup the cost. |
Which column you fall in depends on your model, your bills and your switchboard — that's what the free assessment establishes. Our retrofit-or-replace guide walks the same decision in detail.
What's actually available
in Queensland right now.
Some Brisbane quotes still lean on rebates that no longer exist. Here's the honest state of play for Queensland — figures as at 2 July 2026, from our rebate checker.
Federal STCs — solar PV
Small-scale technology certificates give a $2,000–$3,000 automatic point-of-sale discount on solar PV, up to around $4,000 for systems of 10kW and above. Your installer applies it at quote — you never claim it yourself. As at 2 July 2026.
Federal battery rebate (CHBP)
The Cheaper Home Batteries program cuts around 30% off an installed battery, delivered as STCs applied at the point of sale — and it steps down again on 1 January 2027. This is the active battery support for Brisbane homes, and it applies to batteries paired with or retrofitted to Fronius systems. We calculate YOUR rebate-adjusted price at quote, never a best-case headline.
QLD Battery Booster — closed
Queensland's state Battery Booster rebate closed in 2024 and is not currently available. If a quote presents it as live money off, that's a red flag about the quote. Feed-in tariffs still apply: SEQ rates are retailer-set, typically 3–10c/kWh; the regional (Ergon) regulated rate is 6.006c/kWh from 1 July 2026.

FAQ.
Yes. Mission Green installs and services Fronius inverters across Brisbane and South East Queensland, and designs battery retrofits around them. Fronius is a premium Austrian string and hybrid inverter brand, and for simple, unshaded roofs it is one of our top choices alongside Sungrow. We design new solar systems around a Fronius string or hybrid inverter, service and diagnose existing Fronius systems — including ones we did not install — and add batteries to systems that already have a Fronius on the wall. Because we install other inverter brands too, a Fronius recommendation from us is a design decision, not a sales quota: if your roof has heavy shading or your goals suit a different inverter or an all-in-one battery system better, we will tell you that at the free assessment before you pay anything.
Usually, yes — and there are two main paths. If your Fronius is a compatible hybrid inverter, a DC-coupled modular battery such as the BYD Battery-Box HVM can pair with it directly, the same way BYD pairs with compatible hybrids from Fronius, GoodWe or SMA. If your Fronius is a string inverter without a battery port, an AC-coupled battery such as a Tesla Powerwall 3 can sit alongside it — your Fronius keeps running the solar side while the battery handles storage independently, with no inverter replacement required. Which path is right depends on your exact model, its age and condition, your switchboard and your evening usage, which is why we confirm it from your actual setup at a free assessment rather than assuming. The federal Cheaper Home Batteries program, which cuts around 30% off an installed battery as point-of-sale STCs, applies to both paths.
A red light or fault code is your Fronius doing its job — it has noticed something outside safe operating limits and shut down to protect itself and your system. That is reassuring, not alarming, but it is not a universal message: the same light can mean a grid voltage issue, an isolation fault or a hardware problem depending on the exact code. The single most useful thing you can do is read the exact code shown on the display or in the Fronius app and write it down, then check it against your inverter's manual. Some faults clear themselves when grid conditions settle; others need an accredited electrician. Mission Green diagnoses Fronius fault codes on Brisbane systems even if we did not install them — and if the honest answer is that it is fine and needs nothing, that is the answer you will get.
Two federal incentives are the live support for Brisbane homes as at 2 July 2026. For solar PV, small-scale technology certificates (STCs) give a $2,000–$3,000 automatic point-of-sale discount, rising to around $4,000 for systems of 10kW and above — your installer applies it at quote. For batteries, the federal Cheaper Home Batteries program cuts around 30% off an installed battery, delivered as STCs applied at the point of sale, and it steps down again on 1 January 2027. Queensland's state Battery Booster rebate closed in 2024 and should not appear as live money off on any current quote. On the export side, SEQ feed-in tariffs are retailer-set and typically 3–10c/kWh, while the regional Ergon-area regulated rate is 6.006c/kWh from 1 July 2026 — low enough that self-consumption and storage, not exports, drive the value of a Brisbane system.
Before you pay any deposit.
A Fronius on the brochure doesn't tell you who's on the roof or who answers the phone in year four. The best protection is the checks you run before you sign — run these on us, too.
The 4 checks that separate a keeper from a phoenix
Before you pay any Brisbane installer a deposit — us included — check: 1) How long has the trading entity existed, and is the ABN current? 2) Who's actually accredited to be on your roof — is the installer SAA-accredited and named? 3) Is the workmanship warranty backed by a currently-trading Australian company you can still reach? 4) Are they quoting you, or selling your lead on? A company confident enough to hand you the checklist is a good sign.
Read our full check-before-deposit guide.A part in a box isn't a fixed system
Even when a manufacturer honours a faulty inverter claim, "return-to-base" warranty often covers the part — not the call-out, the labour, or getting an accredited electrician back to your switchboard. That gap is exactly what a vanished installer's workmanship warranty was meant to fill, and it's why who installs your Fronius matters as much as the brand on the box.
Orphaned Fronius? We'll check it — even if we didn't install it
Bought a Fronius system from a company that's since disappeared? We'll do a free, no-obligation health check on your Brisbane system — even if we didn't install it — and tell you honestly what's still covered and what it actually needs, including "it's fine, leave it alone." It's an assessment, not a new warranty, but it beats ignoring a fault light because you assumed the worst.
Our fault-code guide covers what that light means first.Get an honest Fronius

No obligation. We'll look at your roof, your bills and — if you already own a Fronius — the exact model on your wall, then tell you whether to pair, retrofit, or do something else entirely. Call 03 8612 7234 or book online.
