Operating Limits
Over-temperature Conditions
During inverter operation, when the Freedom X's internal
temperature starts to approach its preset shutdown limit, the
display will show error code E07. If the over-temperature condition
persists, the display will show error code E04. The Status LED
turns solid RED and the inverter will shut down to prevent damage
to the inverter and protect the battery from being over-discharged.
