The purpose of this plugin is to collect data from Power Electronics solar inverters via Modbus.
Usage
This plugin reads the data from Power Electronics inverters via Ethernet TCP. This plugin relies on the Modbus Ardexa plugin, and reads from the following inverter models:
PE Freesun HEM
PE Freesun HEMK
It uses the Modbus Specification, and collects from IP connected inverters, using TCP protocol. It will be run every 5 minutes, by default. Inverter data will be collected to the solar table. The inverter will be interrogated for the following data.
NOTE: choose the config file that corresponds to the generation of the Power Electronics inverter, e.g. Gen2 or Gen3.
The following fields will be collected from the config file PE_inverter_HEM_Gen3.txt.

Arguments
Arguments are as follows:
endpoint. This is either a serial device like /dev/ttyS0 or an IP or DNS like 192.168.1.15
bus_addresses. An RS485 address in the range 2-63. This can be a hyphenated list like 3-10 or a list like 2,5,7,9
--port. This is an optional parameter used in an Ethernet gateway, and is the TCP port used for the gateway. Default is 502
--attempts. This is an optional parameter, and determines how many times to times to attempt to read an inverter value. Default is 1
--delay. This is the delay in seconds between inverter send and receive commands, AND if attempts > 1. Fractions like 0.3 can be used. Default is 0.05
