that occurs when the engine starts may trigger a low voltage shutdown.
•AC Overload Shutdown If you connect an AC load rated higher than 300 watts or 1.3 amps or that draws excessive surge power, the 300 Inverter shuts down.
The PWR light stays on, and the 
light comes on to indicate that the inverter is overloaded.
Note: High startup surge requirements The power, or “wattage” rating of an AC load is the average amount of power it uses. When they are first turned on, many AC loads consume more power than their continuous power rating. TVs, monitors, and electric motors are examples of loads that have high surge requirements at start up. Although the 300 Inverter can supply momentary surge power to 600 watts, some products rated less than 300 watts can exceed its surge capabilities and trigger the AC overload shutdown feature. (See page 22 for troubleshooting procedures.)
•High Battery Voltage Shutdown If a defective battery charging system causes the battery voltage to rise to dangerously high levels, the inverter shuts down
automatically. The PWR light stays on, and the 
light comes on.
•High Temperature Shutdown If the inverter exceeds its safe operating temperature because of insufficient ventilation or a
light stays on, and the 
light comes on. When the inverter has cooled sufficiently, it restarts automatically.
