Delta’s PCS100 and PCS125 Power Conditioning Systems (PCS) are bi-directional energy storage inverters for grid-tied and off-grid use in commercial and industrial (C&I) applications, including power backup, peak shaving, load shifting, PV self-consumption, PV smoothing and more. Their compactness, scalability and reliability make Delta PCSs a wise choice for a wide range of system configurations, including integration with various battery technologies. PCS100 and PCS125 can be connected in parallel to reach multiples of their respective power ratings with the benefit of being controlled as one.
