The inverter logs event 9350 when it asks the battery to change state and the battery does not do so within the set time. The event appears in the inverter event log as the message Timeout for battery status change. First make sure the battery is switched on and is not in a fault state. Next, check that the battery communication cable is assembled correctly and firmly connected. Compare the battery's actual state with the state you expect. If they differ, check that the battery's ambient temperature meets the manufacturer's limits and review the battery management settings. Do not confuse this with event 9308, which means the external battery management cannot be reached at all. For 9308, check the battery communication parameters, such as the IP address. If you cannot find the cause, maintain the battery to the manufacturer's specifications and contact Service.
