InAccess - Model Z-PPC - Zero Export Controller - Datasheet

An increasing number of commercial installations use PV generation to offset their energy usage, provide corporate environmental stewardship and save money. At the same time grid operators need to maintain a reliable, secure supply of electricity to existing customers. Export power limitation schemes serve exactly these two needs, requiring a maximum power export from the installation to the grid. Power Limitation may be specified as “Zero Power Injection” or “Export Limitation”: Zero Power Injection indicates that the customer is not allowed to inject any active power to the grid. Export Limitation is a limit on the amount of power the customer can export to the grid. Both mandates come with strict requirements in timing and accuracy.
