Currently you are sending 13 different messages milliseconds apart, to Azure SQL.
It would be better to send one command that posts all 13 bits of data into the database. To do that you need to join all the separate bits of data back together.
So for example you make the ac_pwr line put the data in to msg.ac_pwr etc etc
Then use the join node to join all the messages back up together, and then create your one database insert query.
