Austrian-built string and hybrid inverters with the longest track record on Australian roofs. The GEN24 Plus hybrids for homes, the Symo range for big three-phase and commercial jobs, and a BYD battery when storage is wanted. Installed by our own SAA-accredited electricians.
Fronius has been building inverters in Austria since the 1990s and has been in Australia longer than almost any other brand. That matters for the one component in a solar system most likely to need attention in its life: the service network is deep, parts are here, and a 20-year-old Fronius still gets supported. The hardware is actively cooled, which is why it holds full output on a 40-degree Melbourne afternoon when passively cooled inverters are throttling back.
We install two families. The GEN24 Plus hybrids for homes, which can run as a plain string inverter today and take a BYD battery whenever you are ready, with a backup power outlet built in from day one. And the Symo string inverters for large three-phase homes and commercial roofs, up to 20kW per unit. System design is on the solar and battery page; this page is about the Fronius hardware.
Residential hybrids and the Symo string range. Warranty is 10 years in Australia with registration.
Symo GEN24 Plus. Primo GEN24 Plus up to 97.6%.
GEN24 Plus 3 to 10kW, Symo up to 20kW.
HVS 5.1 to 12.8kWh, HVM 8.3 to 22.1kWh.
Inverter with registration. BYD battery 10 years.
Battery-ready single phase, battery-ready three phase, or a big string inverter for a big roof.
A single-phase hybrid that runs as a string inverter until you add storage. PV Point gives you a backup power outlet in a blackout even with no battery. The right buy when a battery is a few years off and you do not want to pay for two inverters.
Three-phase hybrid with a BYD Battery-Box Premium HVM stack, DC coupled. Full Backup option runs the whole home on all three phases in an outage. For three-phase homes with ducted heating and cooling, a pool or an EV that want premium hardware.
For large three-phase homes, sheds, farms and small commercial roofs. The Symo 20.0 in the photo runs up to 20kW per unit with two MPPTs, and multiple units run in parallel for bigger sites. IP66 for outdoor mounting, and the long service life Fronius is known for.
Pricing depends on inverter size, whether a BYD battery goes in now, switchboard condition and phase. We quote against your bill with the battery rebates already applied.
Models we install. The BYD battery pairs with either GEN24 Plus.

Fronius and BYD published figures at the time of writing. Model availability and warranty terms change between revisions, so we confirm the exact units on your quote.
From site inspection to switch-on, all done by our own crew. Fronius Service Partner trained, so warranty work is handled by us, not a call centre.
Roof, switchboard, phase and where the inverter can sit (it has a fan, so not outside a bedroom window). We read a recent bill to size the system and check Solar Victoria solar rebate and federal battery discount eligibility.
GEN24 Plus or Symo, BYD now or later, backup scope and the number you actually pay with incentives taken off up front.
Panels up, inverter mounted, BYD stack if ordered, switchboard work done, PV Point or Full Backup wired. SAA-accredited, A-Grade, in-house.
Grid connection and export limit arranged with your distributor, Solar.web set up on your phone, warranty registered for the full 10 years, certificate of electrical safety lodged.
Fronius wins on build quality and a battery-later path. These are what it gets quoted against.
All-in-one stack with 8kWh modules and DC EV charging. Wins when the battery is going in now and you want one box for everything.
SungrowValue string and hybrid inverters with the SBR battery. Wins on price when the budget is the priority.
SolarEdgeOptimiser under every panel. Wins on a shaded or multi-orientation roof where a string inverter would lose yield.
We install the heat pump, the induction cooktop and the EV charger the inverter will be feeding. That changes how we size it.
If storage is two or three years away, a GEN24 Plus now means the battery bolts on without replacing the inverter. We tell you when that path beats buying a full hybrid stack today.
SAA-accredited and A-Grade, on our payroll. The person who quoted the job is reachable after it, and the same crew comes back to add the BYD battery.
Solar Victoria solar panel rebate and interest-free loan, federal STCs on the panels and the federal Cheaper Home Batteries discount on the battery. Checked at inspection, applied on the quote, lodged by us.
The 10-year Fronius warranty needs registration, which we do. PV Point or Full Backup is wired and tested before we leave so the outage plan actually works.

Yes. Fronius is Austrian made, has been in Australia for decades, and has one of the strongest service records of any inverter brand here. It costs more than the Chinese-made options and the fan is audible up close, but for longevity and support it is the benchmark most other brands get measured against.
GEN24 is a string inverter. GEN24 Plus is the same unit with the hybrid battery function unlocked, so a BYD battery can be connected now or later. We install the Plus on homes where a battery is even a possibility, because the upgrade from GEN24 to Plus later costs more than buying Plus up front.
A backup power outlet built into every GEN24 Plus. In a blackout, while the sun is up, it supplies up to about 3kW from the panels to a dedicated power point, with or without a battery. Enough for the fridge, phones and the modem. Full Backup, an option, runs the whole home from the battery.
BYD Battery-Box Premium, HVS or HVM, DC coupled to the GEN24 Plus. Modular 2.76kWh units, so the stack grows from 5.1kWh to 22.1kWh, and modules can be added in place later. Both carry a 10-year warranty.
More than Sungrow, similar to Sigenergy for the inverter alone, and it depends on size, phase, whether a BYD battery goes in and your switchboard. We quote against your bill with rebates taken off. Book the free site inspection for a fixed number.
It is audible up close under full load on a hot day, similar to a quiet split system outdoor unit. Placement handles it: we do not mount a Fronius outside a bedroom window. The active cooling is why it keeps full output on a 40-degree day when passive inverters derate.
Yes. The solar side qualifies for the Solar Victoria rebate and STCs, and the BYD battery with a GEN24 Plus is on the approved product list for the federal Cheaper Home Batteries discount. We confirm eligibility at inspection and apply it all on the quote.
All of Melbourne, from the inner suburbs to the Mornington Peninsula. We are based in Somerville. See the locations page or call and we will confirm.
Your address, a recent bill and whether a battery is now, later or never. We will size the system, quote GEN24 Plus or Symo, and take the rebates off before you see the number. No obligation.
