Our PCS (power conversion systems) are multi-functional inverter/converter devices. They are offering bidirectional power conversions (AC->DC and DC->AC) for electrical energy storage, together with optional modules for on-grid and off-grid usage in commercial and industrial applications. The switching time for reversing the power flow is less than 100 ms, respective 5 cycles.
We have a wide range of different models, matching with our battery storage systems or your existing storage up to 3.6 MW.
