SOLAR INVERTER CABINET ARCHITECTURE

摘要

A cabinet for a solar power inverter is described. A solar power inverter receives DC current from a solar panel and transforms the DC current into AC current. To cool the inverter equipment, an air inlet receives ambient air drawn into the cabinet by an air pressurizer. The ambient air is urged into a pressurized air plenum, from which two ports channel the air into at least two air paths to flow over the equipment in the cabinet. The equipment in the cabinet is arranged such that the air passes over more heat-sensitive equipment before reaching less heat-sensitive equipment. The equipment in the cabinet can be separated by grounded, metal walls to contain and diminish electromagnetic interference. The equipment may be accessed from a single, front side of the cabinet.
