About Fronius

SolarBazaar lists 20 products from Fronius, concentrated in inverters. Every listing on this page is drawn from the same catalogue, so the specifications, categories and prices below can be compared directly against any other brand in the directory.

The catalogue breaks down into 2 categories — 18 inverters and 2 batteries. Inverters are where the brand is deepest, with 18 of the 20 listings.

Listed Fronius prices run from £ 576 to £ 6,816 (GBP), which reflects the spread between the brand's entry-level units and its largest or most feature-complete models. Prices are indicative and move with supply, import duties and exchange rates — use them to compare brands, not as a quotation.

Across those listings we hold 135 published specifications, including MPPT Trackers, IP Rating, Power Rating, Weight (kg) and On Grid / Off Grid. Where a manufacturer publishes a figure, it appears on the product page as a field you can compare, rather than being buried in a datasheet.

What Fronius makes: Inverters explained

An inverter converts the direct current (DC) produced by solar panels and stored in batteries into the alternating current (AC) that household appliances, pumps and the utility grid actually use.

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.

  • the MPPT voltage window, which decides how many panels go in a string
  • peak and weighted (European/CEC) efficiency, typically 96–98.5%
  • topology — on-grid, off-grid, hybrid or micro
  • 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

How to choose an inverter

The guidance below applies to any inverter, Fronius's included. Work through it against the specifications listed on this page before you compare prices — a cheaper unit that does not fit your voltages, currents or protocols costs more in the end.

  • Match the battery communication protocol (CAN bus or RS485) between inverter and battery. Compatible voltages are not enough; without a supported protocol the battery management system and inverter cannot agree on charge limits.
  • 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.

What buyers get wrong

  • 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.

Buying Fronius in United Kingdom

Product availability on SolarBazaar is scoped by country, so this page shows the Fronius range listed for United Kingdom plus any items published globally. Switching country in the header changes both the catalogue and the currency prices are quoted in.

SolarBazaar is a comparison directory rather than a shop: we publish specifications, prices and documentation so you can shortlist equipment, then buy from a local distributor or installer. That matters for warranty — cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Fronius in United Kingdom before ordering.

If you are still shortlisting, SMA, SolarEdge and Victron Energy are listed in the same category and can be compared against Fronius spec by spec.

Fronius — frequently asked questions

How many Fronius products are listed on SolarBazaar?

20 products, spread across 2 categories: 18 inverters and 2 batteries. The count reflects what is listed for the country you are browsing, so it changes if you switch country.

What does Fronius make?

Fronius's listed range is led by inverters (18 of 20 listings), followed by batteries (2). An inverter converts the direct current (DC) produced by solar panels and stored in batteries into the alternating current (AC) that household appliances, pumps and the utility grid actually use.

How much do Fronius products cost?

Listed Fronius products run from £ 576 to £ 6,816 (GBP), depending on capacity and model. Prices are indicative and change with supply, duties and exchange rates, so treat them as a comparison reference rather than a quotation.

Is Fronius a good brand?

SolarBazaar does not rank manufacturers editorially — we publish the specifications so you can judge them against your own requirements. For Fronius, the practical checks are the 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 and maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect, and whether the warranty is serviceable in United Kingdom. A brand with strong specifications and no local support presence is often the more expensive choice over a system's life.

Where can I buy Fronius products in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and prices here to shortlist, then buy through an authorised distributor or installer in United Kingdom — that route keeps the manufacturer's warranty intact, which direct grey-market imports usually do not.
