Inaccess Z-PPC: Accurate control for Zero Export PV installations

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. Inaccess Z-PPC satisfies Export Limitation requirements for the most rigorous grid, using the plant inverters and meters/relays, providing near real-time capabilities for plant active power control. 

Indicatively, Z-PPC has been successfully commissioned in the recently inaugurated IKEA store in Columbus Ohio, providing accurate zero export limitation, while maximizing energy usage compensation from the store’s 1.2MWp PV array.
