This implements a direct RS485 connection to a solar inverter in the
|
|
PVI-3.0/3.6/4.2-TL-OUTD ABB series, and may work on others.
|
|
The inverter was formerly made by PowerOne who got taken over by ABB.
|
|
|
|
The TCP/IP method of communicating with inverters is supported by the
|
|
Python library, but not by this implementation in this integration.
|
|
|
|
This integration creates the inverter as a device with three sensors, reporting live power output in Watts, energy generated in kWh and device temperature.
|
|
|
|
Note the PV inverter will be unresponsive to communications when in darkness,
|
|
so the sensors will report 'Unavailable' during the night.
|
|
|
|
The RS485 connection can be made using a low-cost USB-RS485 converter. It works using a 2-wire interface but an interface with a separate ground reference may be more reliable.

The inverter will need to be on (i.e. in daylight) and connected correctly in order to do the first-time setup. Normally it is sufficient to select the correct serial port and leave the default address `2`.
