Maximum efficiency
for utility-scale projects


High Round Trip Efficiency (RTE)

High efficiency that allows to improve 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.

Low power derating, high power capacity at 1500Vdc, wide operating temperature range


Grid connection

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

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

Fast frequency response Synthetic inertia Grid forming in parallel operation with the grid


Battery oriented

Safety centered design with instantaneous controls and monitoring.

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, up to 1500Vdc, including: li-ion, lead-acid, flow and others.
