Battery Temperature

What does 604 mean?

This status code indicates that the battery temperature is outside its permitted operating range for the Fronius Primo GEN24 208-240 inverter. This can be caused by the battery operating in excessively hot or cold environments, or by a malfunction of the battery's internal temperature sensor.

• The battery is operating in an ambient environment where the temperature is too high.
• The battery is operating in an ambient environment where the temperature is too low.
• A fault with the battery's internal temperature sensor, providing inaccurate readings.
