The Volta 15 ZERO is a 3-in-1 mobile energy system, developed for construction sites, telecom locations and infrastructure projects without a grid connection where the strictest emission requirements apply. The system combines solar panels, a battery pack and a methanol fuel cell as backup in one integrated system.
The Volta 15 ZERO is our quietest and cleanest mid-power solution. A proven 3-in-1 energy solution for projects where noise and emissions are simply not an option. With a continuous output of 1.8 kW and a peak output of 12 kW.
Completely whisper-quiet. Nitrogen-free. Particulate-free. Power, always.

of available energy.
The Volta 15 ZERO combines three technologies that work seamlessly together, controlled by smart software.
1. Solar panels
The amorphous solar panels generate energy during the day and charge the batteries. They continue to produce energy even in cloudy or rainy weather. The Volta 15 ZERO operates completely silently and with low emissions at all times.
2. The battery
The 31.2 kWh LiFePO4 battery stores the generated energy and supplies power at any time of day, continuously even when the sun isn’t shining.
3. Methanol fuel cell
Is the capacity insufficient, the methanol fuel cell automatically kicks in. A fuel cell operates electrochemically: no combustion, no internal combustion engine, no noise. Methanol is converted directly into electricity. The result: a backup that is completely silent, emits no nitrogen or particulate matter, and with a significant CO₂-reduction. The fuel cell switches off automatically as soon as the system is self-sufficient again.
The three technologies work together continuously. The system monitors itself and is monitored remotely by the Volta Energy team.
