0X38 - Measured Value Query "Get Inverter Status Extended - Fronius IG 300 Bedienungsanleitung

0x38 - Measured The "0x38 - Get inverter status extended" command is used for the extended querying of
value query "Get the current inverter status. In the event of an error, the relevant status code is also output.

Explanation of "Inverter Status" byte:

0x04
Please see the operating instructions for the relevant inverter for an explanation of status
codes.
Example of status code 301:
0x01
168
NOTE! In the event of a query, the inverter outputs every status code that is pres-
ent until the codes are no longer present. To prevent the inverter from outputting
an unnecessarily high number of status codes, it is recommended that a filter or
timer be implemented for queries to the inverter.
An example of circumstances under which the inverter may output an unneces-
sarily high number of status codes:
in the morning and the evening, when the solar radiation is very low and the in-
verter would issue the status codes "DC low" or "Power low" to every query.
In the event of uncertainty regarding the use of the 0x38 command, it is recom-
mended to use automatic display of status codes for inverters (0x07) - for more
detailed information, see chapter "Automatic Display of Status Codes", section
"0x07 - 'Set error sending' (Automatic Display of Status Codes - Inverters)".
