About Firman Generators

It’s rare to find a power generator manufacturing company with so much interesting history. The generator equipment brand Firman Generators is a part of the SUMEC group of companies, specializing in trade and service, engineering contracting, and investment development, which was set up back in 1978. This was the year that marked the beginning of China paving its way to becoming a tour de force in global manufacturing when Chairman Mao stepped down from power. SUMEC happened to be one of the first few companies since the country’s stringent communist rule relaxed slightly, leaving a global footprint and creating a long history in the manufacturing industry. 

Firman was established in 2001, and its launch also marked SUMEC’s entrance into the global portable generator market. A short six years later, Firman was being touted as the top export brand from China. Joining forces with American heavy hitter generator and engine brand Kohler Engines in 2014 was a definite landmark, adding to their repertoire their partner company’s rich 140 years of experience. They entered the North American market the following year, and by 2017, Firman had evolved into a force to reckon with, having exceeded 10 million units. 

Providing their services in over a hundred countries and regions across the globe, Firman products can be used in an array of fields such finance, medicine, industrial production and construction, as well as day-to-day life. They’ve been tirelessly committed to creating efficient and clean generating equipment for their customers, and providing them with a reliable supply of power while cutting back on energy consumption as much as possible.

There’s a slight sense of skepticism that accompanies products manufactured in China; if that is the rule, this is definitely an exception. In 1997, the SUMEC group began their own research and development into the process of development of large power generation plants in Asia, and they derive much of their experience of the generator market from having built top-quality large-scale grid-linked generators here. Partnering with some of the best-respected manufacturers all over the world, Firman has consistently remained on top of new product developments and innovations to stay at the top of the game. With a range of upcoming innovations at their research and development facilities, Firman holds over a hundred patents across several countries, and is looking at a promising future in manufacturing power equipment.

Warranty, Quality and Return Policies: Details

While Firman is pretty confident that the need for post-purchase service is rare, it offers a generous three-year warranty on every generator and inverter they sell. You can register for the warranty here.
