AuroraPy

AuroraPy is a python implementation of Aurora communication protocol for Power-One Aurora inverters.

It implements a serial Client and a TCP Client for who wants to convert RS485 to Ethernet.

Pip installation

pip install aurorapy

Manual installation

git clone git@code.energievalsabbia.it:ccatterina/aurorapy.git
cd aurorapy
python setup.py install

Usage

TCP Client

from aurorapy.client import AuroraError, AuroraTCPClient

client = AuroraTCPClient(ip='192.168.1.34', port=502, address=10)
client.connect()
try:
    print("Inverter serial number: %s" % client.serial_number())
except AuroraError as e:
    print(str(e))
client.close()

Serial Client

from aurorapy.client import AuroraError, AuroraSerialClient

# AuroraSerialClient(address, port, baudrate=19200, parity='N',
#                    stop_bits=1, data_bits=8, timeout=5)
client = AuroraSerialClient(port='/dev/ttyUSB0', address=10)
client.connect()
try:
    print("Inverter serial number: %s" % client.serial_number())
except AuroraError as e:
    print(str(e))
client.close()
