Commercial buildings
Offices, hotels, retail and car parks that want chargers for staff, guests or company vehicles, without putting the rest of the installation at risk.
Technically sound solutions, tailored to every project
We design and install electric vehicle chargers for commercial and residential buildings, along with solar power plants and electrical power installations. From site assessment to commissioning.
For chargers to work reliably, the whole power path has to work: from the building’s grid connection, through the distribution board, to every vehicle. Click the chargers, choose their power and see what happens when several vehicles plug in at the same time.

Offices, hotels, retail and car parks that want chargers for staff, guests or company vehicles, without putting the rest of the installation at risk.

Many residents, one grid connection. A solution that lets chargers be added gradually and costs be shared clearly.

A home charger and, if you wish, a solar system, designed to work together with the existing installation.

Synetra Engineering is a Belgrade-based engineering company that designs and delivers EV charging infrastructure, solar and electrical power systems.
We start every project with the building, not with an equipment catalogue: how much capacity there is, how the space is used and what will be needed in a few years’ time. Only then do we choose a solution and take it through design, installation and testing, up to the handover of documentation.
We work with investors, building managers, property owners and designers, in Belgrade and across Serbia. Our designers are licensed by the Serbian Chamber of Engineers.

Send us the basic details of your building. We will get back to you within 2 working days.
