Overview
Please note: The Fronius Primo GEN24 Plus is gradually being replaced with a new SC (superior current) version, if the size you are looking for is 'Out of stock' please see the SC version . The Fronius Primo GEN24 Plus, with power categories of between 3 and 10 kW, is the ideal hybrid inverter for private households. With many features as standard, the single-phase device covers all customer requirements. Whether it is used in photovoltaics, a storage system, grid back-up, heating or e-mobility, the Fronius Primo & Symo GEN24 Plus offer a unique range of solutions for both single-phase or three-phase systems. They can be combined with BYD Battery-Box Premium HVS/HVM storage systems to create a competitively priced storage solution for quality- and cost-conscious system owners. A Fronius Smart Meter and an internet connection are also required for operation. The GEN 24 Plus boasts a light and compact design, an active cooling concept, and quick and easy installation and commissioning. The service concept, whereby individual parts can be replaced, also guarantees easy repair and therefore contributes to its sustainability credentials. Features PV Point integrated basic backup power function. GEN24 units include a power socket that is automatically supplied with electricity in the event of a power outage. Automatic activation in case of a grid outage Costly additional installation work is not necessary Supplies households with single-phase loads of up to 3 kW Can operate even without battery (depending upon sunlight levels) Full Backup Option By using additional switchgear, power can be supplied to single or three-phase devices in a whole property in the event of a power outage. Supplies the entire household Automatic switch to backup power in the event of grid failure See Related Products below for backup switchgear. Multi-Flow Technology DC and AC energy flows can work in parallel even in grid backup mode. This allows energy from the PV array and from the battery to work together seamlessly with the battery being charged or discharged as appropriate. The battery can be charged from both the DC and the AC side meaning the inverter can also be AC-coupled to existing PV systems. Active Cooling Technology Using an innovative fan housing, which is integrated into a recess of a die-cast aluminium heat sink with specially arranged cooling fins. Long service life for the inverter Higher yields Flexibility in system design Dynamic Peak Manager Uses MPP algorithm with tolerance of shading Maximum yields even in the case of partial shading Avoids the need for power optimisers SuperFlex Design Uses 2 MPPT trackers with a wide DC input range Enables maximum flexibility in system design Potential problems with different roof orientations and partial shade avoided Monitoring & Communication PV system monitoring using Fronius Solar.web allowing system data and potential for optimisation potential visible at all times Energy Management using 4 digital I/Os to increase self-consumption Open interfaces allow easy integration of third-party components such as heat pumps or Smart Home systems. These include Modbus RTU/TCP SunSpec, Fronius Solar API, LAN, WLAN Configuration notes: Only one GEN24 inverter in a system can have a battery connected Warranty 2-year Fronius Warranty Plus + 3-year Fronius Warranty Plus and 5-year Fronius Warranty upon registration Fronius Warranty - The Fronius Warranty offers warranty protection for the material over the entire service life. Fronius Warranty Plus - The Fronius Warranty Plus covers the material, servicing, and transport costs. Warranty extensions available up to 20 years

What these specifications mean
Fronius Primo GEN24 Plus is listed with 12 published specifications from Fronius, including MPN of 4,210,140,002, power rating of 3000W, MPPT trackers of 2 and phases of Single phase. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For an inverter, the figures that matter most are surge or peak rating, which covers the brief inrush of motors and compressors, maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect, the MPPT voltage window, which decides how many panels go in a string and peak and weighted (European/CEC) efficiency, typically 96–98.5%. It is the component that decides what a solar system can do: how much power you can draw at once, whether you can export to the grid, whether the system keeps running in a blackout, and how well the panels and battery are managed day to day.
Choosing an inverter: the checks that matter
The checks below apply to any inverter. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Look at the warranty term and what it covers. Five years is the common baseline, ten is offered by stronger brands, and extensions are often cheaper bought with the unit than later.
- Size the inverter against the loads you need to run simultaneously, not against the total wattage of every appliance in the building — a 5 kW inverter comfortably runs a fridge, fans, lights and a couple of ACs, but not all of them plus a water pump starting at the same time.
- Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.
- Check the surge rating if you run motors — deep-well pumps, compressors and older air conditioners can draw two to three times their running current for a few seconds at start-up.
Common mistakes
- Ignoring the ambient temperature rating. Inverters derate in heat, so a unit rated 5 kW at 25 °C may deliver noticeably less on a hot roof-adjacent wall at 45 °C.
- Assuming any grid-tie inverter keeps the lights on during an outage. Standard on-grid units shut down for safety unless they have a dedicated backup or islanding output.
- Overlooking the IP rating. An outdoor installation needs at least IP65; indoor-rated units mounted outside fail early.
Price and availability in United Kingdom
Fronius Primo GEN24 Plus is listed at £ 1,549 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Fronius locally before ordering.
Fronius Primo GEN24 Plus — frequently asked questions
How much does Fronius Primo GEN24 Plus cost?
Fronius Primo GEN24 Plus is listed at £ 1,549 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

Who makes Fronius Primo GEN24 Plus?
Fronius Primo GEN24 Plus is a Fronius product, listed under inverters with model reference FR-4.210.140.002. The Fronius brand page lists the rest of its range so you can compare across the catalogue.
Is Fronius Primo GEN24 Plus right for my system?
That depends on what it has to connect to. For an inverter, check the MPPT voltage window, which decides how many panels go in a string, peak and weighted (European/CEC) efficiency, typically 96–98.5% and topology — on-grid, off-grid, hybrid or micro against the rest of your equipment before price enters the decision. Keep the panel array between roughly 1.0 and 1.3 times the inverter's rating. Slight oversizing (a higher DC-to-AC ratio) captures more energy on cloudy mornings and winter days; going far beyond it wastes generation through clipping.
Where can I buy Fronius Primo GEN24 Plus in United Kingdom?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
