GE Inverters


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


The purpose of this plugin is to collect data from GE Solar Inverters via Modbus. The GE_LV5.txt (default) file collects data from GE LV5 Solar Inverters. The plugin uses the Modbus TCP Specification, and collects from TCP connected inverters only. 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. Please be aware that the GE servers may be accessed on Port 503,instead of the normal Port 502. Additionally, the inverters will not always have all 16 string currents connected, so there are some additional config files with different amounts of string currents.

Also note that GE have a unique way of handling negative numbers in 16 bit integers. Rather than using 1 or 2's complement, they use the Signed Magnitude Method as discussed in: This is handled by this plugin, to show negative numbers. The following inverter data will be collected to the solar table:

Arguments are as follows:

  • endpoint. This is either an IP address like

  • bus_addresses. The bus address of the inverter(s)

  • --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
