Confirming Inverter Operation
To confirm that the inverter is operating correctly:
◆ Disconnect the AC input power by turning the input AC power
breaker off or unplugging the AC power cord.
• The inverter should transfer to inverter mode immediately. This
will be indicated by the INVERT (yellow) LED illuminating.
• The inverter will begin to produce an low audible “buzz” as it
takes power from the batteries and uses it to power the loads.
• The loads should continue to operate uninterrupted.
This completes the functional test. If all tests pass, the inverter is ready for
use. If any of the inverter’s internal set points are to be adjusted, consult
the programming chapters of this manual.
