Please note, that the inverter serial number is not supported on all devices and also depends on the internal inverter controller s production date and its Software-Version.

If the inverter serial number is not supported, then two fallbacks are implemented that are still unique but may not match the inverter serial number printed on the nameplate:

1: serial of inverter controller (PMC) if supported

2: Unique ID (UID) of inverter controller

For SYMOHYBRID Inverters the Inverter serial number is not supported and this register always contains one of the two implemented fallbacks.

Please note further that due to startup timing issues or synchronization faults this field may change its value during operation from one option to another, eg.: At boottime only UID is available and after some time device information is synchronized then this field changes from UID to PMC or inverter serial number.

Please note that this register has a scale factor in Register InOutWRte_SF, so for InOutWRte_SF = -2 the valid range in raw values is from -10000 to 10000.

Please be aware that setting an invalid power window will be silently ignored by the inverter.
Invalid power windows are all windows where condition:
((StorCtl_Mod == 3) AND ((-1) * InWRtg > OutWRtg))
evaluates to true.
This can happen for example if two negative values are written into InWRtg and OutWRtg and both limits are activated by StorCtl_Mod = 3.
