Our solutions: battery-powered generators designed for professionals
At PESS Energy, we design and manufacture a complete range of battery-powered generators for professionals in France. These emission-free, quiet, powerful, and mobile solutions power energy-intensive equipment in challenging or urban environments. With three charging options, our systems offer great flexibility.
Wattman in action at Eiffage: the testimony

Hervé, Business Manager at Eiffage Energie Systèmes Réseaux et Solutions, shares his feedback:
“We needed a battery-powered generator capable of providing high power for short periods for arc welding or electrofusion work. Conventional thermal generators present many constraints: noise, fuel, grounding, and pollution risks. With the PESS Energy model, it’s more practical, safer, and the power is immediately available.”
The challenge for Eiffage was not so much autonomy as the instantaneous availability of power, particularly for peaks related to HDPE welding work.
“At night, in the city, the absence of noise changes everything. Even if it’s a little more expensive, for equivalent power, it’s well worth it. Plus, the possibility of charging via solar power or bypass is a real bonus.”
Finally, the robustness of the equipment is highlighted:
“The product exudes quality. The welds are impeccable, the finish is very clean. You can tell it’s professional equipment, far superior to standard products. Even with the Wattman model, the chassis inspires confidence.”
