This is caused by low intermediate circuit DC voltage. This can be caused by a missing supply voltage phase from a blown fuse or faulty isolator or contactor or internal rectifier bridge fault or simply low mains voltage. POSSIBLE FIXES: Check mains supply and fuses. . Overloading the inverter by connecting appliances that draw too much power is a frequent cause of problems. Inverter Won't Turn On If your power inverter fails to turn on, there are a few potential causes to investigate: Ensure the DC input cables are securely connected to the battery terminals. . The severe fault condition will not be cleared, and the fault indication and high voltage disconnect command will remain in effect. What are the minor faults? Minor faults include: transformer overheating alarm, cabinet overheating alarm, cabinet door opening, unit bypass. The input voltage should match the rated voltage of your inverter, which is usually 12V, 24V, or 48V for DC input.
