Key Benefits

<p>Proteus PCS-E Inverters combine reliability and robustness, efficiency, compactness and high power capability at 1500Vdc, all for a minimum Levelized Cost of Storage (LCoS)</p>

High Round Trip Efficiency (RTE)

<p>High efficiency that allows to improve the overall system RTE and LCoS.</p> <p>&nbsp;</p> <p>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.</p>

Battery oriented

<p>Battery agnostic design to accommodate different battery technologies, up to 1500Vdc, including: li-ion, lead-acid, flow and others. Safety centered design with instantaneous controls and monitoring.</p> <p>&nbsp;</p> <p>Double power module topology for two independent battery connections allowing for much lower DC short-circuit currents and increased system availability.</p>

Higher Power

<p>Up to 5470 kVA at 850 Vrms. This high-power design allows savings by using less units per project.</p>

Better LCoS

<p>Compact design which allows 2-inverter solution of up to 11000 kVA in a standard 40 ft skid, achieving overall cost reduction by using less</p> <p>units per project.</p> <p>&nbsp;</p> <p>Design with best-in-class component that guarantees less probability of failure and therefore less operation cost .</p>

Reliability

<p>Smart liquid-air CoolBrid cooling system that allows critical components to work at temperature level far below the limit, guaranteeing product life span.</p> <p>&nbsp;</p> <p>“Easy to support” concept, with heavy components in removable trays, reducing maintenance and repair time (MTTR).</p>

Advanced Grid integration

<p>Four quadrant operation for full active and reactive power support to comply with the most demanding grid codes.</p> <p>&nbsp;</p> <p>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.</p>
