Under normal operation, which statement is true about the inverter control settings?

• A. Inverter selector AUTO and inverter control AUTO
• B. Inverter selector AUTO and inverter control ON
• C. Inverter selector ON and inverter control AUTO
• D. Inverter selector OFF and inverter control AUTO

Answer: (A)

The inverter is designed to be managed by two controls: a selector and a control switch. The selector determines whether the inverter is operated automatically or manually, while the inverter control determines whether the inverter is commanded on or off. In normal operation you want automatic coordination, so both are set to AUTO. This lets the system start the inverter when there’s a demand for AC power and shut it off when it isn’t needed, preserving power and ensuring proper power quality. Forcing the inverter on (or off) or locking the selector to a non-auto position would bypass that automatic coordination, leading to unnecessary power use or loss of available AC power when it’s required. Hence, the best setting is both in AUTO.
