METER ADAPTER AND SYSTEMS

A microgrid comprises a meter adapter for interconnection to the electric grid, facility loads, and renewable energy resources using connectors, bus bars, and switches. Adapter connectors and internal bus bars and can be stressed with excessive heat rise from heat losses that arise from carrying high currents due to constraints in the physical size and airflow restrictions. Exhaust ports and/or vents are arranged to achieve a chimney cooling effect in such conditions to meet stringent UL requirements against resultant heat rise within a meter adapter.
