Lack of output power using power inverter

1. If the inverter is not adequately warming up, you will need to turn the inverters power switch "Off" and then "On" again. Repeat if necessary.
2.  Make sure you turn ignition switch to accessory position. The automotive system requires ignition to be on.
3. If battery voltage is below 10.5 volts, recharge or replace battery.
4. Reduce load to a maximum of 400 watts.
5. If the inverter in thermal is in shutdown condition, allow the inverter to cool down. Ensure adequate ventilation around the unit.
6. Also, make sure the load is no more than 400 watts for continuous operation.
7. If the inverters fuse is blown, replace the fuse.
8. Be sure the inverter is connected to a power source with correct voltage and polarity.
