  If your Cobra inverter has no output voltage, there could be several reasons: * The inverter might be switched off, so turn the inverter on. * There might be no power to the inverter, so check the wiring. * There might be a short circuit, so check the load for proper operation. * The input voltage may be low, so recharge the battery and check connections and cables. * The DC polarity may be reversed, so observe the correct polarity.

  If your Cobra inverter has no output voltage after prolonged use, it could be due to thermal shutdown. Allow the inverter to cool off. Reduce the load and the continuous operation input current required. Improve ventilation, making sure ventilation openings in the inverter are not obstructed, and reduce the ambient temperature.
