Overview

Please note: The Fronius Primo GEN24 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, single phase inverters, with power of between 3 and 10 kW, is the ideal inverter for private households. Includes an integrated basic backup power supply . Backup power is supplied to connected devices up to 3 kW via the PV Point socket, as long as the sun is shining. The smart device design combined with intelligent software enables fast and flexible installation and delivers optimum yields, even when the PV modules are in the shade. What’s more, the integrated active cooling extends the service life of the inverters, securing your customers’ investment. 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 whilst the sun is shining. Automatic activation in case of a grid outage Costly additional installation work is not necessary Supplies single-phase loads of up to 3 kW Operates without battery (depending upon sunlight levels) 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 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 Upgrade to GEN24 PLUS With the Fronius UP.storage* software upgrade, the Fronius GEN24, can be retrofitted with a battery connection at any time, including the Full Backup option. By combining with a battery, you can get even more out of your photovoltaic system, even at night. Use more of your own electricity and become more independent of electricity providers and prices. *Please note, FUP – Fronius Up Program is expected to be available in the UK in 2025.

Reading the specifications

Fronius Primo GEN24 is listed with 1 published specification from Fronius, including MPN of 4,210,140. 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 continuous AC output in kW, which caps the load you can run at once, 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 and the MPPT voltage window, which decides how many panels go in a string. 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.

What to check before ordering

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.

Where buyers lose money

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.
Buying on peak-watt price alone. A cheap inverter with a narrow MPPT window forces awkward string layouts and can strand a portion of the array.

Price and availability

Fronius Primo GEN24 is listed at £ 1,157 (GBP). 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 your country: 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 — frequently asked questions

How much does Fronius Primo GEN24 cost?

Fronius Primo GEN24 is listed at £ 1,157 (GBP). 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.

What are the specifications of Fronius Primo GEN24?

We hold 1 published specification for this inverter, including MPN 4,210,140. The full table is on this page, listed under model FR-4.210.140.

Who makes Fronius Primo GEN24?

Fronius Primo GEN24 is a Fronius product, listed under inverters with model reference FR-4.210.140. The Fronius brand page lists the rest of its range so you can compare across the catalogue.

Is Fronius Primo GEN24 right for my system?

That depends on what it has to connect to. For an inverter, check 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% against the rest of your equipment before price enters the decision. Confirm the inverter is approved by your local utility or distribution network before you buy if you intend to export power — grid connection depends on certified anti-islanding and local grid-code compliance, not on the inverter's specifications alone.

Where can I buy Fronius Primo GEN24?

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 — buying in-channel is what keeps the manufacturer's warranty valid.
