Satcon Inverters

Purpose

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

Usage

This plugin collects from Satcon Inverters. Specifically, the following inverters will be collected:

AE-225-60-PV-D
AE-225-60-PV-A

It uses the Modbus protocol and collects data via TCP or RS485. Inverter data will be collected to the solar table and will be run every 5 minutes, by default. This plugin relies on the Modbus Ardexa plugin. The following data will be collected:

Arguments

Arguments are as follows:

• configuration file. This is the configuration file for the inverter type. Choose from the list provided.

• endpoint. This is either a serial device like /dev/ttyS0 or an IP or DNS like 192.168.1.15

• --bus_addresses. This is an optional parameter, and is the modbus address for the inverter. This usually sstarts with "1", for the first inverter.

• --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
