This set of scripts are used to query the Aurora Inverter of a Solar Plant via the serial2lan network device. Here I use <socat> to establish the connection to the network serial2network converter. Then I use the local virtual serial port to query the inverter by the aurora open-source terminal application.

aurora_alert.sh

#!/bin/bash

# Downloads the alert queue from the inverter
# to a local text file

logfile="`dirname $0`/alert.log"

cmd="/root/aurora_monitor/aurora_socat.sh"

date >>$logfile
$cmd -a 2 -A 2>>$logfile | grep -v "No Alarm" | grep -v ^$ >>$logfile 2>>$logfile

aurora_dspinfo.sh

#!/bin/bash

cmd="/root/aurora_monitor/aurora_socat.sh"

$cmd -a 2 -Y 8 -d 0 -D -3
