What to do if my Duracell 1000 has no output voltage and the Fault Light is on?

If the Fault Light is on and there's no output voltage from your Duracell Inverter, it could be due to several reasons: low or high input voltage, thermal shutdown, unit overload, or a short circuit. To resolve this: * Recharge the battery and check the connections and cable, ensuring the inverter is connected to a 12V battery. * Check the voltage regulation of the charging system. * Allow the unit to cool off, improve ventilation, and ensure the ventilation openings are not obstructed. Reduce the ambient temperature. * Reduce the load to ensure it does not exceed the inverter's output rating. * Remove any short circuits.
