Is ABB A Good Brand?

ABB has undergone lots of ups and downs in these 33 years. It’s the perfect example of not giving up at any cost. So, before I give you an answer on whether ABB is a good brand or not, let me give you a quick brief on its company.
ABB was founded in 1988 in Zurich, Switzerland; it was a merger of two companies named ASEA and Brown, Boveri & Cie. These two companies were formed in 1883 and 1891 respectively and were involved with electrical goods like motors, circuit breakers, robots etc.
ABB provides an all-inclusive range of power converters and solar inverters for a variety of applications across all industries. The power converters and inverters of ABB help you to generate and use energy efficiently. It is designed in such a way so that it can withstand any sort of conditions and that too at a low price. You can undoubtedly rely on ABB as its power converters and solar inverters are backed by global support and service.
Furthermore, ABB’s commitment towards technical innovation and manufacturing has been acknowledged, and it has been awarded as the Manufacturer of the Year at the Motion Control Industry (MCI) awards.
This MCI award is proof that ABB is one of the only few manufacturers that offer both VSDs (Variable Speed Drive) and motors that combine the perfectly matched motor and drive packages made just for you!
ABB invests heavily in the development of next-generation motion technology; it offers comprehensive life cycle services to maintain the reliability of its products. And for this very reason, they are known as the market leaders in the supply of motors and drives. More so, ABB won Supplier of the Year at the Pump Industry Awards.
ABB has Ability Smart Sensor for low voltage motors, which offers just the right thing- you can now monitor the condition of most low voltage motors at a very low price. This Smart Sensor converts low voltage motors into intelligent, connected machines. The predictive maintenance based on data from this sensor can help you to reduce the downtime by up to 70%. It can also extend the motor lifetime by 30 %, and it can cut energy consumption by up to 10%.
And then there’s the Smart Sensor which is part of the ABB solar inverters portfolio that includes more than 180 digital solutions! It uses the industrial internet to create digitally connected devices, systems and services that increase productivity, cut maintenance costs and reduce energy consumption. ABB is definitely an all-in-one package.

Oh, wait! It doesn’t stop here; ABB has world-leading manufacturing facilities; for instance, its 25,000 sq.m Helsinki factory is home to VSD (Variable Speed Drive) and R & D initiatives.

There are over 20 different laboratories at the site supporting production, R&D and customer applications. And you won’t believe it, but the factory produces some 200,000 variations of frequency converters and solar inverters each year! Unbelievable, isn’t it? 

Additionally, ABB has its own field service engineer network, backed up with local support through its authorised value provider channel to support its drives and motors in the field.
Therefore, ABBs hard work and willpower earned them these awards, which is a testament to their success serving these diverse industries as ABB today is writing the future of industrial digitalisation. I am sure by now you got an answer of whether ABB is a good brand or not. Because it indeed is, and no matter what its past was, I can assure you that ABB won’t disappoint you.

ABB and FIMER Partnership

ABB was a premium manufacturer that offered a wide range of high-quality string solar inverters; in 2014, ABB bought forth one of the smallest yet famous companies called ‘Power One’, which was known as ‘Aurora’.
Unfortunately, things got out of hand, and it gained a poor reputation because of the ‘Aurora’ solar inverters. The customers were facing issues such as technical problems and poor customer support; as a result, ABB’s solar inverter began to lose its reputation. And just for this one mishap of ABB Aurora solar inverter, it had its negative impact on their other standard quality type inverters as well.
Thus, in July 2019, ABB decided to opt out of the business. And just in time, FIMER came to the rescue in early 2020. FIMER solar inverter is the fourth largest Italian based solar inverter distributor. It has a production capacity of 4.12GW with a string inverter range from a few kW to 7.8 MW; held the hands of the ABB’s business and finalised the acquisition.
ABB, in spite of having a terrible startup, with their years of playing around the Aurora inverters, finally got through all the infamy by starting from scratch. It reintroduced their technically advanced inverters called the UNO inverter series. And it was only possible with the help of the FIMER, the guardian angel of ABB.

Where Is ABB Solar Inverter Manufactured?

ABB’s inverter, as mentioned earlier, are manufactured in Italy. You might worry about the pricing of the inverters, as ABB is a multi-billion-dollar industrial giant, but that is the last thing you should worry about. As these top-notch inverters are cheap and come with great customer support.
Although ABB’s solar inverters are manufactured in Italy, but you will be amazed to know that it has got not one, but four offices in Australia- situated in 4 states, including Sydney, Brisbane, Melbourne, and Perth and their head office is situated in Sydney, NSW. So, without any hesitation, you can drop in your queries, and within no time, ABB’s correspondents will be solving your problems.

ABB Inverter- Is It Any Good?

If you want a straightforward answer without me being biased or anything- then I can tell you for a fact that the ABB inverters are compared to SMA and even Fronius inverters. Yes! You heard that one correct. ABB inverters are one of the most preferable inverters in the Australian market.
I agree they had their share of loss because of that one inverter. But it’s high time we see the progress, hard work and dedication towards the best. This inverter has an efficiency of 97% with an impeccable amount of features solely for your benefit.
Furthermore, it has a switch called “DC isolator” that needs to be operated manually. It works as a safety mechanism, as the switch shuts off the DC current between the solar panels and the solar inverter. If any problem arises in your solar panels and someone comes to fix them, they will be safe from being electrocuted.
