Solivia Inverters

Purpose

The purpose of this plugin is to collect data from Solivia Inverters.

Usage

This plugin reads data from Solivia Inverters, via serial or TCP. Inverter data will be collected to the solar table. By default, it will collect data every 5 minutes, but can collect at a minimum rate of 30 seconds. The plugin will make an attempt of (by default) 3 times to read an inverter, with a default sleep time 0.2 seconds between each read. See the Ardexa documentation instructions for connecting Solivia Inverters via serial line. The following variables will be collected. Please note that AC Power is the addition of AC Power 1+AC Power 2+AC Power 3, since AC Power is not collected natively by Solivia inverters.

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 4001

• --baud. This is an optional parameter used to detail the serial baud rate. Default is 19200

• --attempts. This is an optional parameter, and determines how many times to times to attempt to read an inverter value. Default is 3

• --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 0.2
