Red and green LED Indicators on top of your inverter will show the status of the inverter and alert you to conditions that could cause the inverter to shut down.

If the inverter is overloaded, it will shut down to protect itself. The red LED will illuminate to indicate Overload Protect. To restore normal operation, disconnect the excessive load and turn the unit off and on again using the Power Button.

If the DC input voltage drops below 11 volts, the red LED will light up to indicate Low Voltage Protection, but the unit will continue to operate. If the input voltage drops to 10.5V or less, the inverter will shut down to protect the battery, the red LED will be lit and the alarm will continue. To restore normal operation, return the DC input voltage to at least 12V. The inverter will automatically return to normal operation.

If the DC input voltage rises above 15 volts, the inverter will shut down to protect itself, the red LED will light up to indicate a high voltage protection. To restore normal operation, return the DC input voltage to less than 15 volts. The inverter will automatically return to normal operation.
CAUTION: Although the inverter has protection against over-voltage, it may still be damaged if the input voltage were to exceed 16 volts.

If the internal inverter temperature rises above the alarm threshold, the unit will continue to operate. If the internal temperature rises to 104ºF, the inverter will shut down to protect itself.
NOTE: Internal inverter temperature can rise due to being operated in a high heat environment or due to the fan or vents being blocked during operation (even in relatively cool outside air). To restore normal operation, turn the unit off and allow it to cool. The inverter will automatically return to normal operation after it has cooled.

The USB outlet will supply 5 volts at 500ma to charge and power cell phones, iPods® and other small electronics.

The inverter can deliver 300 watts for about 60 minutes. The inverter must cool for 15 minutes before it can resume operation at 300 watts.
NOTE: Operating time will vary depending upon the type, capacity charge level of the battery, and the power draw of the AC products you are using. With a normal vehicle battery and a 100 watt load (such as a small television) you can expect an operating time of 2 to 3 hours. It is recommended that you start your vehicle once an hour when using the RPPD300 for extended periods of time to prevent draining the battery.
