Energy

Power without interruptions — from an apartment to a plant

One of the two directions our reputation rests on. We size the system to the real load, supply the equipment and arrange the installation — for homes, businesses, communities, public facilities and tender projects.

What we do in energy

Backup power

Inverters with batteries and power stations: the boiler, the fridge, the till and the connection keep working through outages.

Solar plants

Hybrid and grid systems for homes and businesses — a payback calculation, two ready options.

Industrial BESS

Storage systems of 100–250 kW for plants, communities and tender projects.

Turnkey installation

Our installation team mounts the system — a separate service at an additional price.

Ready solutions and the calculator — in our energy shop

Kits with prices and hours of runtime for an apartment, a house, a café, a pharmacy, an apartment block.
