Inverter PCS 250KT
High power bi-directional invertor AC/DC for energy storage applies multi-level T-type technology to achieve 99% transformer efficiency, active power control, reactive compensation and high/low voltage ride-through.
It is resistant to short circuit, DC reverse polarity, overvoltage and current overload. It supports three-phase operation in symmetrical and asymmetrical systems.
