Anleitung Zusammenfassung
This protects the battery from being over-discharged. It will restart when the input voltage exceeds 12V+/-0.3V. The inverter will also shut down if the input voltage exceeds 15.5V+/-0.5V. This protects the inverter against excessive input voltage. Although the inverter has protection against over-voltage, it may still be damaged if the input voltage were to exceed 16 volts. High Temperature Over Temperature Protection – If the internal inverter temperature rises above the alarm threshold, the meter will flash as shown, an alarm will sound to indicate Over Temperature Protect, and the unit will continue to operate. If the internal temperature rises to 40.C (104.F), the inverter will shut down to protect itself, the meter will flash as shown and the alarm will continue to sound. NOTE Internal inverter temperature can rise due to being operated in a high heat environment or due to the fan or vents being blocked during operation (even in relatively cool outside air). To restore normal operation, turn the unit Off and allow it to cool. The inverter will automatically return to normal operation after it has cooled.

To protect the battery, if the unit needs to be restarted after low voltage protection, the voltage of DC input should be above 12V. To extend the life of the fan, it will stop when there is no load. The speed of the fan increases as the load increases. The unit is completely insulated in input and output for added safety. Troubleshooting Guide Problem/Symptom Low output voltage No output voltage No output voltage after prolonged use No output voltage, “Protect” indicator lighted No output voltage No output voltage Low battery alarm on all the time Possible Causes Overload Low input voltage Thermal shutdown High input voltage Short circuit Inverter switched off No power to inverter Reverse DC polarity Poor DC wiring Poor battery condition Solution Reduce the load. Recharge battery. Check connections and cable. Allow inverter to cool off. Reduce load, continuous operation input current required. Improve ventilation; Make sure ventilation openings in the inverter are not obstructed. Reduce ambient temperature. Make sure the inverter is connected to 12V battery. Check regulation of charging system. Check load for proper operation. Turn inverter on. Check wiring to inverter. Observe correct polarity. Check connections. Make sure battery is fully charged.
