Operating Limits

Power Output:

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.

WARNING: To prevent personal injury or loss of life, never start or leave your engine running in a poorly ventilated area such as a garage.

Helpful Formulas:

To Convert AMPS to WATTS: AMPS X VOLTS = WATTS

To Convert WATTS to AMPS: WATTS ÷ VOLTS = AMPS

These formulas yield a close approximation of the continuous loads of a product.

To calculate approximate Startup Load: Multiply: WATTS X 2 = Starting Load

This formula yields a close approximation of the starting load of the appliance, although some may require an even greater starting load. NOTE: Induction motors such as air conditioners, refrigerators, freezers and pumps may have a start up surge of 3 to 7 times the continuous rating. Most often the start up load of the appliance or power tool determines whether an inverter has the capability to power it.

For example: You have a freezer with a continuous load of 4 amps, and a start up load of 12 amps:

4 amps x 120 volts = 480 watts continuous, 12 amps x 120 volts = 1440 watts starting load

You would need an inverter with peak-surge rating greater than 1440 watts to run this appliance.
