Overview of Fronius – Company History

Founded in Austria on June twentieth 1945, Fronius is a global firm with a 75 12 months historical past within the manufacture of welding gear and almost three many years of expertise with solar inverters and different units for monitoring and controlling energy, together with battery chargers.

Fronius launched its first grid-connected solar inverter again in 1995. Since then Fronius has grown to develop into one of many trade main solar inverter producers, with 19 of 28 workplaces worldwide being concerned with solar energy. This consists of the Australian workplace positioned in Tullamarine, Victoria.

Fronius inverters are appropriate for a variety of functions, together with residential solar and industrial solar initiatives, together with their not too long ago launched Fronius Tauro inverter with 100kW capability.

 

A Brief Rundown on Solar Inverters

A solar system’s inverter is the purpose at which the DC electrical energy produced by solar panels is become grid-compatible AC electrical energy.

String inverters have historically been the usual within the solar trade. They ship the power produced by solar panels to a central inverter that modifications it from the DC electrical energy to the usable AC electrical energy that powers properties.

Microinverters, then again, convert DC to AC electrical energy at every particular person panel and permit for monitoring and power regulation on the panel stage. This is beneficial for properties which might be positioned someplace with shading from clouds, bushes, or different buildings.

 

What is PV Evolution Labs Top Performer?

PV Evolution Labs (PVEL) independently take a look at solar inverter reliability. The assessments are voluntary, with solar inverter producers paying to take part within the testing. This testing course of is internationally famend and is an correct reflection of the solar inverter’s efficiency. To learn the complete PVEL scorecard click on right here.

In 2019 the Fronius Symo ranked as a high performer within the following assessments:

    • High Temperature Operation
    • Transient Response
    • Ground and Arc Fault

Fronius Inverters – Point of Difference

Fronius SnapINverters

A novel facet about Fronius inverters is the SnapINverter know-how. It’s a standardised wall mounted bracket with the inverter on a hinge system. This permits quick access for servicing because the inverter opens like a automobile boot, while not having to be faraway from the wall.

Fronius Galvo

The Fronius Galvo is ideal for family self-consumption programs, with power classes starting from 1.5 to three.1kW. It consists of the next superior options.

  • Automatic High-Frequency Transformer Switchover
  • Integrated Data Communication
  • Smart Grid Ready
  • Zero Feed-In

Fronius Primo

The Fronius Primo is a transformerless single-phase inverter with power classes starting from 3.0 to eight.2kW, making it a really perfect possibility for a residential family inverter. It consists of the next superior options.

  • Integrated Data Communication
  • Superflex Design
  • Dynamic Peak Manager
  • Smart Grid Ready
  • Zero Feed-In Capability

Fronius Symo

The Fronius Symo is a transformerless three-phase inverter with power classes starting from 3.0 to twenty.0kW. This power vary permits the Fronius Symo inverter to be relevant to the vast majority of residential solar programs. It consists of the next superior options.

  • Integrated Data Communication
  • Superflex Design
  • Dynamic Peak Manager
  • Smart Grid Ready
  • Zero Feed-In

Fronius Eco

The Fronius Eco is a transformerless three-phase inverter designed for large-scale installations. The commercially used inverter is available in 25 or 27kW power classes. The Fronius Eco inverter holds an Ingress Protection Rating (IP Rating) of 66, this implies it’s dust-tight and in a position to stand up to heavy seas or highly effective jets of water. Both power classes maintain an effectivity ranking of over 98%, and as a result of built-in double fuse holders and optionally available overvoltage safety, string assortment bins aren’t required.

It consists of the next superior options.

  • Integrated Data Communication
  • Dynamic Peak Manager
  • Smart Grid Ready
  • Zero Feed-In Capability

All of Fronius’ inverters are manufactured in Austria and include CE certification. The CE mark lets the purchaser know that the product in query has met the legislated EU necessities for that sort of product. The concept is that the legislated requirements ought to be enough to guard customers from sub-standard merchandise. This high quality assurance is a part of the rationale why Fronius is likely one of the trade main producers of inverters. 

 

Fronius Inverter Efficiency

Residential inverter effectivity requirements are usually 95 to 98 p.c, the Fronius Primo & Symo sit at or above 98% effectivity putting them in the direction of the highest of the trade in residential inverter effectivity.

Inverter effectivity know-how will be seen within the Fronius Galvo. This inverter utilises an automated high-frequency (HF) transformer with three effectivity peaks. This permits the next share yield because the HF transformer is extra environment friendly throughout the complete enter voltage vary.

 

Fronius Inverter Value and Warranty

An essential facet of getting essentially the most worth out of a solar inverter is to decide on an appropriately sized inverter to optimise the solar panel system effectivity. To learn concerning the significance of inverter sizing and system effectivity click on right here.

Fronius inverters seize worth by way of quite a lot of their parts, nevertheless, their trade first information communication bundle is showcasing the evolution of solar inverters. The information communication connects to the web offering the flexibility to watch energy administration and information logging. This info permits the system proprietor to extend their self-consumption fee, subsequently decreasing reliance on grid power.

Both the Fronius Primo and Symo fashions utilise the Fronius Superflex Design. This design creates worth as the 2 most power level trackers (MPP) allow the lodging of the complete nominal inverter output, no matter roof orientation or partial shading. The inverters monitor the MPP by way of the Dynamic Peak Manager algorithm, this dynamically adapts the optimum working level.

In Australia, all CEC authorised Fronius inverters include a 5 12 months guarantee for elements and labour. A free extra 5 12 months extension (elements solely) to the guarantee will be claimed by way of, registering at solarweb inside 30 months of the manufacturing unit inverter dispatch. A guaranty extension will also be bought from the inverter installer inside 30 months of the inverters dispatch from the Fronius manufacturing unit. This will be for 10, 15 or 20 years, making the longest doable guarantee 25 years.

 

Fronius Inverter Costs

As Fronius inverters are manufactured in Europe this increased high quality product comes with the next price ticket compared to the inverters which might be manufactured in China.

Keep in thoughts that inverter prices usually solely run between 10-20% of your complete system, so typically it’s price investing in a top quality inverter given this can have a big influence on the effectivity and efficiency of your whole system.

 

A Full Range of Fronius Inverters Available in Australia 

The majority of Fronius’s Inverters are authorised by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program. A notable exclusion is the Fronius Symo Hybrid, this method combines a battery charging system, battery inverter, hybrid inverter, controller and system monitoring resolution in a single 3-5kW gadget.

Example of a Fronius Commercial Solar Project 

The Philippines has seen fairly an increase within the variety of solar programs being put in over the previous few years. This is as a result of public grid being unable to reliably provide power to the 13 million Filipinos residing within the metropolitan space surrounding Manila.

In April of 2019 a subject positioned in Tarlac City, Philippines had a 20MW system outfitted with 612 Fronius Eco inverters go stay. The system included 61,200 solar panels to complete the 20MW, the set up was accomplished in 5 months.

By putting in the Fronius Eco the general potential yield of the panels was elevated. Although, for an set up of this magnitude it’s uncommon for the inverters was string inverters. However, it’s due to the string inverters that the system is ready to be extra environment friendly. String inverters work higher in situations resembling partial shade in comparison with central inverters. It was estimated that the system will produce round 32,000MWh of electrical energy, decreasing CO2 by round 18.6million kg.
