Fimer (ABB) Overview – Company History

Arturo Sottocorno created Fimer S.p.A in 1942 as a welding equipment producer. Fimer’s headquarters are in Vimercate, which is in Italy. Solar and e-mobility will be Fimer’s key business segments in 2022. Fimer employs over 1100 people worldwide, with direct operations in 26 countries across five continents. Fimer is able to maintain a distribution network of over 100 countries because to its three manufacturing facilities and three research and development centers.

Fimer’s solar branch was founded in 2007 and has since evolved to become the world’s fourth largest provider of solar inverters. Fimer completed the acquisition and integration of ABB’s inverter division in March of 2020. The deal comprised all of ABB’s manufacturing and research and development facilities in Finland, Italy, and India, as well as 800 personnel spread across 26 countries.

“We will have the ability to utilize the ABB name in combination with Fimer for the next three years,” Fimer CEO Filippo Carzaniga said in an interview about the branding of Fimer ABB Inverters. According to this statement, Fimer may continue to produce inverters under the ABB name for the next few years.

A Quick Overview of Solar Inverters

The inverter in a solar system converts the DC electricity generated by solar panels into grid-compatible AC electricity. String inverters, hybrid inverters, micro inverters, and power optimisers are the four types of solar inverters.

In the solar business, string inverters (such as Fimer’s) have long been the standard. They transport the power generated by solar panels to a central inverter, which converts it from DC to AC electricity that may be used to power dwellings.

What is the top performer at PV Evolution Labs?

PV Evolution Labs (PVEL) has been independently testing solar panel reliability since 2014, with help from DNV GL, and has now tested solar inverters for the first time in 2019. It is a paid optional test that manufacturers must participate in. Solar panel testing is widely regarded as an excellent indicator of solar panel quality around the world. Inverter testing is likely to be recognized in the same way. Click here to read the entire PVEL scorecard.

Inverter Warranty from Fimer (ABB)

Fimer (ABB) single-phase home inverters are CEC approved and come with a 10-year manufacturer’s guarantee as standard in Australia. The five-year manufacturer’s warranty on the three-phase home inverters can be extended to ten years. The guarantee period begins when the inverter is installed or six months from the date of manufacture, whichever comes first.

All ABB Inverters installed before Fimer’s acquisition of the ABB Inverter business will have their warranties honored, according to Fimer.

Costs of Fimer (ABB) Inverters

Residential inverters made by Fimer (ABB) are made in Italy, which implies they will be more expensive than those made in China.

Pricing that is only indicative

  • $1,000 to $1,200 Fimer UNO-DM-TL-PLUS-Q 3.3kW Inverter
  • Inverter Fimer UNO-DM-TL-PLUS-Q 4kW $1,100 to $1,300
  • Inverter Fimer UNO-DM-TL-PLUS-Q 5kW $1,200 to $1,400

Keep in mind that inverter costs often range from 10% to 20% of the total system cost, therefore it is frequently worthwhile to invest in a high-quality inverter because it will have a significant impact on the efficiency and performance of your Solar Power project.

Example of a Fimer (ABB) Commercial Solar Project Made in Italy

Costa Rica is home to this ABB inverter installation. Because of the country’s unique climate and location, renewable energy sources provide for nearly all of the country’s energy needs. In recent years, renewable energy sources such as hydro, solar, geothermal, and wind have gained popularity.

Costa Rica was able to supply 100 percent of the country’s electricity from renewable sources throughout most of 2018. It is the country’s goal to generate all of its electricity from renewable sources.

ABB supplied inverters for Costa Rica’s largest solar farm, which produces enough energy to power 10% of the country’s population. 28 ABB PVS-175 String Inverters and 1 ABB PVS-175-MVCS were used in the farm (medium voltage compact skid). Prior to the acquisition, this installation was completed.
