40,000 hours lifespan

This translates to more than 5.000 cycles, or over 1.600 days of continuous operation.

Hybrid system

The two models in the Medium range offer rated power of 15kVA and 45kVA, and energy storage capacity of 45kWh. The units are easy to connect to the generator thanks to a wide range of socket options.

ZERO fuel and CO2 emissions

It helps operators to dramatically reduce their fuel consumption and CO2 emissions, while delivering optimal performance with zero noise and virtually no maintenance.

70% more compact and lighter in weight

High-density lithium-ion batteries are lighter than other technologies. Weight and size reduction means that the units can be transporting without any specialist equipment.

12 hours autonomy

Provides over 12 hours of power with a single charge (1.5 hrs. charging)

Zero Noise

Unlike generator-powered solutions where the sound of the engine is impossible to eliminate, batteries operate silently.

ZBP, medium range Energy Storage System

The ZBP have a footprint of just 1.5 m2, which means that they are 70 percent smaller and lighter in weight than traditional standalone generators. Their size, which has a lot to do with their high-density lithium-ion batteries, brings a new level of versatily and usability. Without compromising on power, these Energy Storage Systems have a working life of over 40.000 hours. This contributes to a very low Total Cost of Ownership.

Although all medium and large Energy Storage Systems can operate in hybrid mode and as a standalone solutionthe ZBP are the perfect fit for certain applications. Due to their size and capacity, they are ideal for telecom instalations in remote locations. In metropolitan construction sites, they can be used to balance out the peaks in demand and low loads. Also, these Energy Storage Systems can operate in emissions-free and noise-sensitive areas where generators can't. Of course, the ZBP can also work storing energy coming from renewable sources. 

Hybrid mode: 24 hours at a construction site
