Solis

This is a Python module to interact with Solis Invertors connected via the Solarman v5 data loggers.

It builds on top of the pysolarmanv5 module to provide structured data output that can be consumed without needing to the know the registers and data formats of the underlying device.

CLI Usage

Module usage

Due to the overhead of the modbus protocol of reading a small number of registers each time, the module has been designed to read all registers at once using the Solis.async_update() method, then various properties provide formatted access to relavant registers. e.g.

solis = await Solis.create(ip, serial, port)
await solis.async_update()
print(solis.bastt_change_level)

See solis.py for exposed registers.
