Key features of the Fronius Gen24 Plus Inverter
The Fronius Gen24 Plus Inverter packs several standout capabilities into one hybrid unit. Here is what sets it apart from a basic solar inverter.
- Two backup power options: The unit offers backup power even without a battery, through the PV Point socket, which delivers up to 3 kW during a grid outage while the sun is shining. Pairing it with a compatible battery unlocks Full Backup, keeping your entire home powered through an outage, including larger appliances like fridges and induction cooktops.
- Battery compatibility: The Fronius Gen24 Plus is designed to work natively with BYD Battery-Box Premium HVS and HVM high-voltage battery modules, letting you store excess solar energy for use at night or during a blackout. Certain LG RESU Flex battery models are also supported, depending on region and configuration, giving households more than one storage brand to choose between.
- Smart energy management: Self-consumption optimisation and load shifting are built in, prioritising solar power for your home and shifting flexible loads, such as pool pumps, hot water systems, or dishwashers, to sunny periods to reduce grid reliance.
- Multifunctionality: Beyond converting solar power, the Fronius Gen24 Plus Inverter integrates with heat pumps, EV chargers, and other smart home devices to form a broader energy management ecosystem rather than acting as a standalone box on the wall.
- Easy monitoring and control: Built-in WLAN and Ethernet connectivity let you track the system remotely through the Fronius Solar.web platform, covering production, consumption, and battery status from a phone, tablet, or laptop.
- Flexible system design: With two independent MPP trackers and a wide DC input voltage window, the inverter suits complex roof layouts, shaded strings, multiple orientations, and future panel additions without needing a second unit.

Applications for the Fronius Gen24 Plus Inverter
The Fronius Gen24 Plus Inverter suits a wide range of Australian households looking to get more from their solar system:
- Energy independence: Generate solar power during the day and store the excess in a compatible battery, reducing what you draw from the grid at night and during peak pricing periods.
- Blackout protection: PV Point and Full Backup give the system real resilience during outages, from powering essential circuits like fridges and lighting to running the whole home.
- Future-proofing: The scalable design lets you add a battery later without replacing the inverter, making a Full Backup Fronius Gen24 Plus Inverter setup more affordable than it was at the time of this model’s launch.
- EV and heat pump integration: Homes adding an EV charger or a heat pump can route that load through the inverter’s energy management features, prioritising solar rather than grid power for charging and heating.
- New builds and retrofits: Because Primo and Symo variants cover single-phase and three-phase properties, the Fronius Gen24 Plus fits both new-build solar installs and retrofits onto existing switchboards, provided there’s suitable wall space near the meter box.
Pros of the Fronius Gen24 Plus Inverter
- Flexible backup power: The Fronius Gen24 Plus Inverter offers two backup tiers, a PV Point for essential loads during daylight and Full Backup for whole-home protection once a battery is added.
- High efficiency: Conversion rates on this inverter are strong across both Primo and Symo variants, so more of the solar energy your panels generate actually reaches your home rather than being lost in conversion.
- Native battery compatibility: Integration with BYD’s high-voltage battery range means a Fronius Gen24 Plus Inverter system can be sized closely to a household’s real storage needs, rather than forcing a one-size-fits-all battery choice.
- Future-proof technology: Smart meter compatibility and open interfaces mean the system can adapt as home energy management, EV charging, and time-of-use tariff structures continue to evolve.
- Single-phase and three-phase options: Primo and Symo variants cover different property configurations, from standard homes to larger three-phase builds and some small commercial sites.
- Wide power range: Spanning 3 kW to 10 kW, the Fronius Gen24 Plus Inverter fits most residential rooftop systems without needing a different product line for larger arrays.
Cons of the Fronius Gen24 Plus Inverter
- Higher upfront cost: The Fronius Gen24 Plus Inverter typically costs more than a basic string inverter of the same power rating, reflecting its hybrid capability and backup functionality.
- Battery sold separately: Fronius doesn’t manufacture batteries, so a compatible BYD unit adds meaningfully to the total cost of a Full Backup system, and battery pricing can vary between installers.
Is the Fronius Gen24 Plus Inverter right for you?
Weigh up these factors when deciding if the Fronius Gen24 Plus Inverter fits your household:
- Backup needs: If whole-home blackout protection matters most, pair the inverter with a battery for Full Backup. PV Point is a lower-cost option if you only need essential loads covered during daylight outages, with no battery required.
- Power requirements: Most Australian homes suit the Primo, or single-phase, version of the Fronius Gen24 Plus Inverter, while three-phase properties should look at the Symo variant instead for balanced power distribution.
- Budget and rebates: With the federal Cheaper Home Batteries Program discounting eligible battery systems by around 30%, pairing a battery with the Fronius Gen24 Plus Inverter is more affordable today than it was when this model first launched.
- Scalability: The system is designed to accommodate battery expansion later, so you aren’t locked into today’s storage capacity if your household’s energy use grows over time.
A qualified solar installer can confirm the right system size, battery capacity, and backup configuration for your home before you commit to a Fronius Gen24 Plus Inverter installation. Getting a couple of independent quotes is a reasonable step before signing off on any hybrid inverter and battery package, and it’s worth asking installers directly whether Full Backup or PV Point best matches how you use power at home.
Overall, the Fronius Gen24 Plus Inverter remains one of the more flexible hybrid inverters available to Australian homeowners, particularly for households planning to add a battery, an EV charger, or a heat pump at some point rather than all at once. Its combination of established local support, a field-serviceable design, and native compatibility with well-known battery brands makes it a reasonable long-term pick, even if it isn’t the cheapest inverter on the shelf.
