While various factors can contribute to an IGBT's demise, three culprits are responsible for the vast majority of field failures: overcurrent, overvoltage, and overtemperature.

When using an inverter, the battery current draw depends on the load (watts), not the inverter rating. 12V systems: divide the load watts by 10 24V systems: divide the load watts by 20 Example: 300W load 12V system: 300 ÷ 10 = 30 Amps 24V system: 300 ÷ 20 = 15.

However, the 4777 standard states that the maximum 10-minute AC over-voltage of an inverter is 258 Volts, (with some grid operators mandating 255 Volts). At this point the inverter must either de-rate or shut down to comply with the standards.
