Maximum efficiency
for utility-scale projects


High Round Trip Efficiency (RTE)

Market leading efficiency of up to 99.45% (IEC 61683), improving the overall system RTE and LCoS.

Smart liquid/air cooling system that allows critical components to work at temperature level far below their limits, guaranteeing longer product lifespan and lower thermal losses.

AEP and UEP product variant for maximum plant power output.


Grid connection

Four quadrant operation for full active and reactive power support to comply with the most demanding grid codes.

Fast frequency control mode with a response time below 150 ms.

Weak grid and micro-grid configuration with a seamless transition and black start capabilities.


Battery oriented

Safety centered design with instantaneous controls and monitoring both hard-wired and through communication protocols.

Double power module topology for two independent battery connections allowing for much lower DC short-circuit currents and increased system availability.

Battery agnostic design to accommodate different battery technologies, including: li-ion, lead-acid, flow and others.


Available to fit any customers' needs

Different product configurations available to optimize performance in demanding environments, IEC and UL certifications, as well as different voltage levels to fit customer's needs.
