skymax

|
--------------------------------------------------------------------------------------
|
|
This project was forked from manio/skymax-demo on git since it allows me to query my
|
|
own Axpert solar inverter. A company in Taiwan called Voltronic sells a hardware plat-
|
|
form used in many different brands of inverter. My brand just happens to be one of
|
|
those Voltronic clones so all the same commands apply.
|
|
|
|
--------------------------------------------------------------------------------------
|
|
compilation / running
|
|
--------------------------------------------------------------------------------------
|
|
(You will need cmake, make and gcc already installed. Use apt-get to get them)
|
|
|
|
Sample build/compilation procedure:
|
|
$ git clone https://github.com/nrm21/skymax-demo
|
|
$ cd skymax-demo
|
|
$ mkdir out
|
|
$ cd out
|
|
$ cmake ..
|
|
$ make
|
|
|
|
Then you need to get the real hidraw device name (probably hidraw0):
|
|
$ dmesg | grep hidraw
|
|
|
|
and then run the program like this (assuming it is located in '/opt/skymax/out' dir):
|
|
$ /opt/skymax/out/skymax
|
|
|
|
The program will run once, it will spit out values it receives from the inverter in
|
|
JSON format and exits. It was intended to be run by telegraf using the exec plugin
|
|
every 15 seconds, and that output data will be imported into an InfluxDB instance
|
|
where it can be easily graphed by grafana (or some other "TIG or TICK stack"-like
|
|
software suite).
|
|
|
|
The program can also be made to send raw commands to the inverter if you choose:
|
|
$ /opt/skymax/out/skymax -r POP00 # set utility output mode
|
|
$ /opt/skymax/out/skymax -r POP02 # set SBU output mode
|
|
$ /opt/skymax/out/skymax -r PCP00 # set utility charging mode
|
|
$ /opt/skymax/out/skymax -r PCP03 # set solar only charging mode
|
|
etc...
|
|
|
|
These commands can of course be scripted and put into a cron job to run them at a
|
|
certain time of day/week as well (say, every morning at 8am switch to solar charging
|
|
mode only and SBU output mode).
|
|
|
|
See this protocol manual for more commands that can be sent:
