Overview

Flexible hybrid inverter with powerful emergency power supply. Developed for farms, small businesses as well as larger single and multi-family homes, these hybrid inverters are highly flexible, with 3 high-current MPP trackers and a wide voltage range. They also use an integrated Dynamic Peak Manager algorithm that enables users to achieve optimal yields even in shady conditions allowing installations with complex roof constructions, different module orientations and inclinations or even combinations of different module types to be easily implemented. Powerful emergency power supply When combined with a battery storage system (such as Fronius Reserva), it not only increases self-consumption for homes and businesses but also ensures secure power supply to large consumers 24/7 and even in the event of a power outage. In addition, the Backup Power Boost function in backup mode allows for a temporary increase in output power to ensure critical equipment, such as heat pumps, refrigeration units, ventilation systems, and machines, continue running smoothly. With an integrated surge protection device and an Arc Fault Circuit Interrupter (AFCI), the Fronius Verto Plus guarantees the very highest safety standards even in its basic configuration, without the need to pay for additional components. With Fronius, you can also rest assured that your data is in the best hands, ensured by their certified information security system, servers and cloud storage being located in Europe. Key features: Power classes 15.0, 17.5, 20.0, 25.0, 30.0, 33.3kW 3 MPP Trackers - wide DC voltage range 2 inputs per tracker - no string fuses required Arc Guard AFCI on board as standard AC and DC over voltage protection as standard Overvoltage protection included - DC Type 1+2 / AC Type 2 Warranty Inverters from 13 kW Option 1 - 2-year Fronius Warranty Plus + 3-year Fronius Warranty Plus upon registration Option 2 - 2-year Fronius Warranty Plus + 5-year Fronius Warranty upon registration Fronius Warranty - The Fronius Warranty offers warranty protection for the material over the entire service life.

How to read this datasheet

Fronius Verto Plus is listed with 10 published specifications from Fronius, including MPN of 4,210,450, power rating of 15000W, MPPT trackers of 3 and phases of Three 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 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 and maximum PV input and the number of MPPT trackers, which set how many panel strings you can connect. 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.

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.
Choose a hybrid inverter if a battery is in your plan now or later; retrofitting storage onto a pure grid-tie inverter usually means buying a second unit or an AC-coupled battery system.

Common mistakes

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.
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.

Price and availability

Fronius Verto Plus is listed at £ 3,993 (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 Verto Plus — frequently asked questions

How much does Fronius Verto Plus cost?

Fronius Verto Plus is listed at £ 3,993 (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 Verto Plus?

We hold 10 published specifications for this inverter, including MPN 4,210,450, power rating 15000W, MPPT trackers 3, phases Three Phase and connectivity Ethernet, WiFi. The full table is on this page, listed under model FR-4.210.450.

Who makes Fronius Verto Plus?

Fronius Verto Plus is a Fronius product, listed under inverters with model reference FR-4.210.450. The Fronius brand page lists the rest of its range so you can compare across the catalogue.

Is Fronius Verto 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. 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.

Where can I buy Fronius Verto Plus?

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.
