Fronius inverters — sized, quoted and installed end to end
What Is A Fronius Solar Inverter?
Fronius is an Austrian manufacturer with a long history in power electronics, and its solar division makes string and hybrid inverters used in residential and commercial systems worldwide. An inverter converts the DC electricity your panels generate into the AC electricity your home and the grid use, and Fronius' range spans straightforward single and three-phase string inverters through to battery-ready hybrid models with built-in backup power capability.
Ausgreen Solar Solutions selects, sizes and installs Fronius inverter systems as part of our top-listed product range, matching the model to your panel array, switchboard and household's actual usage pattern rather than a one-size-fits-all package.
☀️ Solar Rebates Can Significantly Cut The Upfront Cost
Eligible solar installations, including qualifying systems paired with a Fronius inverter, can currently attract Small-scale Technology Certificates (STCs) that reduce the upfront cost, on top of any applicable state-based scheme. Exact eligibility depends on the specific system configuration, installation date and your location — our team confirms current entitlements as part of your quote.
Fronius Inverter Options We Install
Fronius' published range covers straightforward string inverters through to hybrid, battery-ready models with backup power — we help you choose the right one.
Fronius Primo (~1.5–8.2kW)
A single-phase string inverter range suited to standard residential systems, with dual MPP trackers on most models for flexible panel string layouts.
Fronius Symo (~3–20kW)
A three-phase string inverter range for larger residential systems and small commercial sites on a three-phase supply.
Fronius GEN24 Plus
A hybrid inverter available in single and three-phase formats, designed to integrate with a compatible battery and provide backup power during a grid outage.
Fronius Solar.web
Fronius' own monitoring platform, included with current inverters, for tracking generation, consumption and system health from a phone or browser.
ℹ️ Specifications Vary By Model & Release
Fronius updates model line-ups, output ratings and certifications from time to time, and not every model is available or CEC-approved at every point in time. The figures on this page describe the general shape of Fronius' published range — your quote will confirm the exact model, output rating and warranty terms recommended for your site.
What Makes A Fronius Inverter Different
Fronius inverters are built around a modular mounting system and weatherproof outdoor-rated housing, backed by a standard manufacturer warranty that can be extended on eligible models.
SnapINverter Mounting System
A wall-mounted bracket lets the inverter body be lifted on and off independently, designed to speed up installation and any future servicing.
Outdoor-Rated Housing
Current Fronius inverters carry an IP66 rating on the connection area, allowing outdoor installation on a suitable wall without an additional enclosure.
Dual MPP Trackers
Two maximum power point trackers on most models allow panel strings facing different directions to be wired and optimised independently.
Battery & Backup Ready
GEN24 Plus hybrid models are designed to integrate with a compatible battery and can power selected circuits during a grid outage via Fronius' PV Point feature.
Integrated DC Disconnect
A built-in DC disconnect switch is designed to simplify isolation for maintenance and improve on-site safety during servicing.
Active Cooling Design
Fan-assisted cooling on current models is intended to maintain output in hot conditions rather than reducing power once the unit heats up.
Fronius Solar.web App
Free access to Fronius' own monitoring portal gives you a live and historical view of generation, self-consumption and system performance.
STC & Rebate Ready
Systems paired with a CEC-approved current Fronius model are eligible for Small-scale Technology Certificates, and pair well with a battery or EV charging setup on suitable sites.

Honest Sizing Advice
We recommend the Fronius model and system size that fits your actual usage and panel array — not the largest inverter we can sell you.
What A Well-Run Inverter Install Looks Like
An inverter is the part of your system doing the most work. These are the things worth getting right from the start.
- Confirm your installer is CEC-accredited and check their track record independently
- Size the inverter to your actual panel array, not just the cheapest matching unit
- Check your switchboard's phase configuration before committing to a model
- Get an itemised quote that separates the panels, inverter, installation and any rebate
- Ask about the inverter's warranty term and any extension options in writing
- Confirm whether the inverter is battery-ready if that's on your future plans
- Set up production monitoring from day one so performance is easy to track
- Choosing an inverter on price alone without checking panel and switchboard compatibility
- Undersizing the inverter relative to the total panel array capacity
- Assuming every inverter model qualifies for the same STC or rebate value
- Mounting the unit somewhere that breaches the manufacturer's clearance or shading guidance
- Not clarifying whether backup power or battery integration is included or optional
- Leaving monitoring app setup and warranty registration until "later"
Government Incentives That Can Reduce Your Solar Cost
Depending on your location, eligibility and the specific system configuration, several government schemes can be combined with your Fronius inverter installation.

Frequently Asked Questions
Is Fronius a reputable inverter brand?
Fronius is an Austrian manufacturer with a long history in power electronics and has been supplying solar inverters to the Australian market for many years. As with any inverter brand, we recommend confirming installer support and warranty terms, which is part of every Ausgreen Solar Solutions quote.
What's the difference between Primo, Symo and GEN24 Plus?
Primo is Fronius' single-phase string inverter range, Symo is the three-phase string inverter range, and GEN24 Plus is the hybrid line designed to integrate with a compatible battery and provide backup power during an outage.
Can I add a battery to a Fronius system later?
A standard Primo or Symo string inverter typically needs a compatible AC-coupled battery added later, while a GEN24 Plus hybrid inverter is designed with battery integration in mind from the outset. We can advise the best path during your site check.
Do Fronius inverters qualify for STCs or other rebates?
Eligibility depends on the specific system configuration and its CEC approval status at the time of installation, along with system size and location. We confirm current eligibility as part of your itemised quote.
What warranty comes with a Fronius inverter?
Current Fronius inverters carry a standard manufacturer warranty with the option to extend on eligible models, with exact terms set out in Fronius' datasheet. Exact terms are confirmed on your quote for the model installed.
How do I monitor my Fronius inverter's performance?
Every current Fronius inverter includes access to Fronius Solar.web, their own monitoring portal, for real-time generation and consumption data. We can also add SkyBox Energy Management for more detailed visibility.
