Note: python2 no longer supported
Python package with reference library of serial commands (and responses) for PIP-4048MS inverters - aka:
- PIP-4048MS
- IPS-4000WM
- Voltronic Axpert MKS 5KVA Off-grid Inverter-Chargers
Now also supports LV5048 inverter commands
Good overview and technical discussion here http://forums.aeva.asn.au/viewtopic.php?f=31&t=4332
- Raspberry Pi 3
- 2x USB to serial adapters (like https://www.adafruit.com/product/18)
- connected to 2x PIP-4048MS inverters connected in parallel
Also
- Raspberry Pi 3
- USB cable to USB port of inverter
- connected to 1x PIP-4048MS (/dev/hidraw0 on Pi)
Also
- Raspberry Pi
- 3x USB to serial adapters
- connected to 3x LV5048 inverters
Also
- Ubuntu 2020.04
- Direct USB connection to Inverter (LV5048)
- see documented approach
sudo python ./setup.py install
- The commands default to using
/dev/ttyUSB0if you are using direct USB connection try adding-d /dev/hidraw0to the commands - if you have other USB devices connected the inverter might show up as
/dev/hidraw1or/dev/hidraw2 - if uncertain, remove and re-connect the connection to the inverter and look at the end of the
dmesgresponse to see what was reconnected - also in some instances only root has access to the device that the inverter is connected to - if you are getting no response try using
sudo- if you want to be able to use a hidraw device as pi (or other users)
- create a file
/etc/udev/rules.d/99-hidraw.ruleswith the below as the contentKERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0660", GROUP="plugdev"- after a restart (or replug of the USB cable) any user of the plugdev group will be able to read from/write to any /dev/hidraw device
- if you are getting no/unexpected results add
-Dto the command to get a heap of extra information
