SYNOPSIS

aurora [Options] -a InverterAddress Device

REQUIRED PARAMETERS

-a <num>, --address=<num>
Inverter address. 1-31 on older inverters, 1-63 on newer inverters.

Device Serial Device. Example, /dev/ttyUSB0 or /dev/ttyS0.

OPTIONS

-A, --last-alarms
Get last four alarms (once displayed FIFO queue is cleared)

-b, --verbose
Verbose mode. For maximum effectiveness should be the first option on the command
line

-C <num[:$]>, --calc-value=<num[:$]>
Calculate monetary value using <num> * kWh. ":$" is optional and if included the
character(s) represented by the "$" will be used to denote monetary type in the
output. Defaults to "$"

-c, --columnize
Output data in columns --> for -d, -e, -D, -3, -E, -t options only, will disable
all other options -- if value ends with an "*" reporting of that item may not be in
inverters firmware

-d <num>, --get-dsp=<num>
Get DSP data <num> indicates string to get data for. 0 indicates both 1 for only
string 1, 2 for only string 2. <num> is required for short option and <num> is
optional for long option and if omitted for long option data for both input strings
will be retrieved

-D, --get-dsp-extended
Get more DSP data

-3, --get-dsp-3phase
Get 3-Phase DSP data

-e, --get-energy
Get Cumulated Energy readings (Excluding Central)

-E <num>, --get-energy-central=<num>
Get Cumulated Float Energy readings (Central & TRIO only) <num> days 1 to 366
Default 366 <num> is required for short option and optional for long option

-f, --firmware-ver
Query for Firmware Version string

-g, --mfg-date
Query for Inverter Manufacturing Date

-h, --help
This text

-i <bitmask>, --get-count=<bitmask>
Display Inverter Time Counters <bitmask> is required for short option is optional
for long option and if omitted for long option then all counters will be displayed
and Partial counter will be reset
1 = "Total Run Time" 4 = "Grid Connection Time"
2 = "Partial Run Time" 8 = "Reset Partial Run Time"

-j, --get-joules
Display Energy accumulated in the last 10 seconds

-K, --use-kmult=<num>
Adjust vaules reported by -k, --daily-kwh by "<num>" multiplier

-k <num>, --daily-kwh=<num>
Get past daily KWH for <num> days (1-366) <num> is optional for long option and if
omitted all 366 days or as many that are found will be displayed. It is suggested
that the -Y option be used with this due to the extensive length of time it takes
to get all the data from the inverter

-L <num>, --adjust-time=<num>
Automatically adjust the inverter time if it differs from the computer time. If
<num> is 0 (zero) do a Daylight Savings Time check. If <num> is >= 1 change the
inverter time if it differs by <num> or more seconds. See the README for more
information and the constraints this option uses to the determine if the time
should be changed due to Daylight Savings Time

-l <num>, --read-wait=<num>
Timeout for the read to the serial port. <num> in 1/10ths seconds. Default is 1
(0.1 sec). See the README file for important information on this option

-M <num>, --max-runtime=<num>
Maximum amount of time in seconds that aurora will run trying to get data from the
inverter

-m, --get-conf
Query for Inverter System Configuration

-n, --serial-number
Query for Inverter Serial Number

-N <num>, --central=<num> ** Experimental **
Indicates Aurora Central 0 indicates Master, 1 indicates Slave

-o <filename>, --output-file=<filename>
Append data to file (Created if nonexistant) Note: If -c option is used only -d,
-e, -D, -3, -E, -t, & -T options will output to file

-O, --part-number-central
Query for Inverter Part Number (Central only)

-p, --part-number
Query for Inverter Part Number

-P <num>, --comm-pause=<num>
Wait <num> uS between sending commands to inverter (1-1000000)

-Q, --use-qmult
Use inverter specific multiplier if known to adjust values reported by -q,
--energy-sent

-q <num>, --energy-sent=<num> ** Experimental **
Get past energy delivered to the grid at 10 second intervals for <num> minutes
(1-1440) starting with the oldest data available. <num> is optional for long option
and if omitted all data, ~24 hours worth will be reported. It is suggested that the
-Y option be used with this due to the extensive length of time it takes to get all
the data from the inverter. See the README file for important information on this
option

-R <num>, --read-timeout=<num>
Serial port read retry timeout value when reading a character from the Inverter (mS
- minimum 200) See the README file for important information on this option

-r, --calc-grid-power
Calc Grid power using Grid Voltage * Grid Current, instead of reporting the
Inverter's value. --> for -d option only, ignored when used with -c option.
(Inverter typically reports a lower value. This affects Inverter conversion
efficiency value.)

-S, --set-time
Set Inverter Date/Time to system time

-s, --get-state
Get Inverter State

-T, --get-loctime
Display computer Date/Time

-t, --get-invtime
Display Inverter Date/Time

-U <num>, --read-pause=<num>
Pause <num> milli-seconds after sending command to inverter before reading response
from inverter (1-10000)

-u, --rpt-read-pause
Report when/that pausing before read

-V, --version
Aurora communications program version

-v, --inv-version
Query for Version string

-W, --swap-endian
Swap Endianness

-w <num>, --lock-wait=<num>
Seconds to wait to lock serial port. (1-30)

-X, --rts-cts
Enable RTS/CTS on the serial port.

-x, --xon-xoff
Enable XON/XOFF on the serial port.

-Y <num>, --retries=<num>
Retry failed communications with inverter up to <num> times (1-100)

-y, --rpt-retries
Report the number of retires done

DESCRIPTION

aurora is a program that communicates with Aurora Magnetek Photovoltaic (solar) Power
Inverters written by Curt Blank. It can retrieve data and statistics from a variety of
Aurora Inverters through either USB or Serial interfaces.

EXAMPLES

aurora -T -c -e -d 0 -a 2 -w 15 /dev/ttyS0

aurora -Y 100 -T -a 2 -w 10 -e /dev/ttyUSB0
