Medium Energy Storage Systems
From 200 to 500 kVA
From 200 to 500 kVA
These energy storage systems come in a 10ft container. Designed to meet the requirements for off- and on-grid applications, they are ideal in combination with renewable stations, providing up to 9,2 MWh of storage capacity ―with 16 ZBC 250-575 units connected in parallel. ZBC models can operate as a standalone solution, in hybrid mode with several sources of energy and as the heart of a microgrid. These medium units are ideal for demanding applications that require a constant and significant flow of electrical energy.
These medium energy storage systems are scalable, as up to 16 units can be connected in parallel. Moreover, when operating in hybrid mode with a diesel generator, users can reduce daily fuel consumption by up to 90%, depending on the application. Stand-alone medium energy storage systems offer no fuel consumption and no CO2 emissions during their operation. This scenario is also common for microgrids with a backup generator, in which the energy storage system is managing the input coming from the grid and/or renewable sources of energy.
If the solution features an active diesel-driven generator, operators will still enjoy significant energy savings, increasing the productivity of their core business by up to 50%. When coupled with a power generator, energy storage systems account for low loads, reducing the generator running hours by up to 70%. This translates into a longer generator lifetime —five to ten years—.

Delivering at less than 80 dB(A), these medium energy storage systems are suitable for noise-sensitive environments, such as events and construction sites in metropolitan areas, as well as for telecom, manufacturing, mining, oil and gas and rental applications.
They are ideal for applications with a high energy demand and variable load profiles, as they efficiently cover both low loads and peaks. For example, they can properly size cranes and other electric motors, and successfully manage peaks in energy demand for noise-sensitive events and for electric vehicles (EV) recharging stations.
Working off-grid or to boost the grid, standalone or in a hyrbid solution, in parallel with other battery energy storage systems or as the central piece of a microgrid, they provide resilient and sustainable energy on demand - helping you lower emissions, meet regulations and cut costs through a seamless integration with low emission innovations.
