MEC – the Better Alternative

About Us

MEC-energijski sistemi, d.o.o., founded in Naklo, Slovenia in 2020, is derived from Mengling Power Electronic (Dong Guan) Co. Ltd., which is in operation since 1989 in China. Before moving ti in Slovenia, the company had its headquarters from 2012 to 2020 in Villach, Austria

With the establishment of Mainland Energy Conversion Ltd. in 1999, we gained a foothold in Hong Kong. MEC is thus an important production and transit partner, aiming to offer customers around the world the highest quality, the best value for money and contemporary OEM products.
