SolarEdge 50kW PCS050 AC Coupled Battery Inverter

SolarEdge 50 kW PCS050 AC Coupled Battery Inverter 50 kW three‑phase AC‑coupled battery inverter for SolarEdge commercial and industrial storage systems, designed to work with the SolarEdge 102.4 kWh Battery Cabinet. Bi‑directional power conversion with up to 55 kW DC input power and <20 ms transition time between on‑grid and backup modes when used with the Commercial Backup Interface. High efficiency (up to 97.5%), IP65 enclosure and integrated protections for dependable long‑term operation on UK and European C&I sites. Overview The SolarEdge PCS050 is a 50 kW three‑phase AC‑coupled battery inverter, supplied as part of the SolarEdge CSS‑OD commercial storage system. It connects to one or two SolarEdge 102.4 kWh battery cabinets and an AC‑coupled SolarEdge PV system, handling charging and discharging of the storage while interfacing with the grid or backup system. The inverter is managed through the SolarEdge ONE optimisation platform, which coordinates site generation, storage and loads for self‑consumption, peak shaving and tariff‑based operation as supported in firmware. When combined with the optional Commercial Backup Interface in supported countries, it can also form part of a microgrid‑type backup architecture. Key features 50 kW rated AC active power output (55 kVA apparent) at 400/230 Vac, three‑phase, with <3% THD. Up to 55 kW DC input power via two DC interfaces, supporting up to two CSS‑OU‑20 102.4 kWh battery cabinets per inverter. Maximum inverter efficiency of 97.5%, with fully bi‑directional operation for charge and discharge. On‑grid and backup operation with overall system transition time <20 ms when used with the SolarEdge Commercial Backup Interface. IP65‑rated, air‑cooled enclosure with integrated Type II DC and Type III AC surge protection, reverse polarity protection and grid, earth fault and leakage monitoring. Typical applications Well suited to logistics hubs, warehouses, light industrial sites, commercial rooftops and similar C&I locations where SolarEdge PV is already installed or planned. Typical uses include peak demand reduction, shifting solar generation into evening operation, and, with the appropriate backup interface, providing support for critical loads during grid outages.
