ABB PVS 800 Inverters


The purpose of this plugin is to collect data from the ABB PVS800 Central Inverters.


This plugin reads the data from ABB PVS800 Central Inverters. This plugin relies on the Modbus Ardexa plugin. It uses the Modbus TCP Specification, and collects from RS485 or TCP connected inverters. Inverter data will be collected to the solar table. The plugin will be run every 5 minutes, by default. The following data is collected from the inverters:

Arguments are as follows:

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

  • 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
