Z-PPC satisfies Power Limitation requirements for the most rigorous grid, using the plant inverters and meters/relays, providing near real-time capabilities for plant active power control. With UNiTY advanced Power Limitation schemes, the EPC and Plant owner may benefit by installing larger PV systems, simplifying design while optimizing the array to meet the needs of the customer – not only the stringiest demands of the utility.

Zero Power Injection has strict timing requirements with the system either not allowed to export at any time or ensure the zero export level with a 2-5 seconds deviation response time.
