Note: python less than v3.6 not supported
Python package with reference library of serial commands (and responses) for MPP and similar inverters, some known to work (to varying amounts):
- PIP-4048MS
- IPS-4000WM
- Voltronic Axpert MKS 5KVA Off-grid Inverter-Chargers
- LV5048
Also supports JK BMS
- JK-B2A24S (HW version 3.0)
- JK-B1A24S (HW version 3.0)
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
pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mpp-solar"
- Download or clone the repo
- From the directory that has the requirements files:
sudo pip install -r requirements.txt# for the minimal install (dependances must be installed manually)sudo pip install -r requirements-serial.txt# for the mqtt install (includes pyserial)sudo pip install -r requirements-full.txt# for the full install (includes pyserial, mqtt and bluepy) Note: needsudo apt-get install libglib2.0-devfor bluepy
for when you want to keep the install and dependencies separate from the rest of the environment
- create venv folder
mkdir ~/venv - create venv
python3 -m venv ~/venv/mppsolar- might need python3-venv installed
- activate venv
source venv/mppsolar/bin/activate(needed each time before using) - pip install from git
pip install -e "git+https://github.com/jblance/mpp-solar.git#egg=mpp-solar"(only needed if the code is updated)
see worked example here
