Define the AC collection boundary
Solar power distribution switchgear may collect inverter outputs, connect transformers, isolate feeders, measure energy, and interface with a grid or facility bus. The correct arrangement follows the plant topology and protection study.
Inputs to collect
| Input | Why it matters |
|---|---|
| Inverter and transformer schedule | Establishes source ratings and connection points |
| AC feeder and bus arrangement | Defines collection, isolation, and maintenance paths |
| Fault and protection data | Coordinates breakers, relays, CTs, and trips |
| Metering and plant controls | Defines energy, status, alarms, and remote interfaces |
| Outdoor environment | Affects enclosure, heat, UV, dust, water, and cable entry |
| Grid or facility requirements | Sets the project-specific interface and evidence |
Scope boundary
This guide does not certify grid compliance or assign protection settings. Confirm the final switchgear with the power-system engineer and applicable project requirements.
