Why does my inverter display error code E01 with equipment plugged in?

An E03 error indicates a power demand overload. Reduce loads connected to the AC outlet of the unit. Check appliances that have high-surge ratings and disconnect. To determine which device might be causing the overload plug everything in one piece at a time starting with devices with the lowest consumption and finishing with those with the highest consumption. If issue persists, contact Newcastle Technical Support. http://www.newcastlesys.com/submit-trouble-ticket
