5 Operating the 150 Inverter

Operating Statuses

This section describes normal operation as well as problems that could occur when you use the inverter. If you have a problem, see “Troubleshooting” on page 12.

•Normal Operation When you connect the inverter to your vehicle’s 12 volt outlet and turn on the On/Standby switch, the green PWR light comes on and AC power is available at the outlet.

The inverter shuts down automatically in response to low battery voltage, high battery voltage, AC overload, overheating, or a short in the AC output.

•Low Battery Voltage Alarm and Shutdown As the battery discharges, its voltage decreases.

When the inverter senses that the voltage at its DC input has dropped to 10.7 volts, it sounds an alarm. This gives you time to shut down computers or other sensitive devices. If you ignore the alarm and the DC input drops to 10.0 volts, the inverter shuts down the AC load being operated. The PWR light stays on, the alarm stays on, and

the light comes on. The low battery voltage shutdown feature saves the battery from excessive discharge, which can prevent you from starting your vehicle, or more seriously, damage the battery.

•Possible shutdown when the vehicle’s engine is started The 150 Inverter will operate while your vehicle’s engine is running, but the normal voltage drop that occurs when the engine starts may trigger a low voltage shutdown.
