: The inverter, which converts battery DC power to AC for your equipment, is a frequent culprit. One user was told the failure might be due to overvoltage or a bad connection within the inverter circuit itself. An internal event code, "Event Code 107," specifically points to "Power Devices in Inverter circuit has been compromised".
