• Audible Alarm (internal to the inverter): The inverter makes a buzzing sound when it senses a
low battery condition. At this time, the user should reduce the connected loads and charge the
battery.
Note: The audible alarm may make a momentary “chirp” sound when the inverter is turned OFF.
This is a normal occurrence.
