The scenario
A rural property in the Enel Ceará concession area seeks homologation of a grid-tied 12 kWp photovoltaic system with a backup generator and automatic transfer switch for critical loads during grid outages.
What is in this drawing
Read the decisions behind it.
01
Integrating PV inverter output and utility grid before the ATS normal input to enable net metering while ensuring generator-only backup via the emergency input.
02
Selecting a bidirectional meter to satisfy utility requirements for exported energy measurement.
03
Sizing the ATS to handle full load current and coordinating breaker ratings for overcurrent protection.
Use this single-line design as a template for similar Enel Ceará homologation projects involving distributed generation with backup sources and transfer switching.
