Two possible problems; input voltage too low, or the output load too high. If input remains at 12v or higher and it shuts off with no load, then the inverter is bad.

2500 superex hooked up to 12v ,has a squeal when I turn a hair dryer, and the volt meader drops from 12v down alot


Is the unit hooked up in a vehicle? If it is, try increasing the engine rpm a little bit to bring the voltage back up. Sounds like the hair dryer is overloading the inverter.

Open the monitor, look for blown capacitors and replace them. If problem persist, test the light bulbs and the inverter. If the inverter includes ceramic capacitor, replace it. If some of the bulbs does not do the flash - replace it. Check the transistors of the inverter. Replace if faulty.

Power going up and down


An incandescent lamp that is cold takes approximately 10 times the running current initially. The inverter MAY not be able to start the 500 watt lamp if its protection circuits sense the very low starting resistance of the lamp.

Test the inverter on some other device first.
