SMA Sunny Webbox
Plugin to collect data from Sunny Webbox via Modbus.
Purpose
The purpose of this plugin is to collect data from a SMA Sunny WebBox.
Usage
The purpose of this plugin is to collect data from SMA Sunny WebBox loggers via Modbus. The SMA_sunny_webbox_device_discovery.txt
file shows the serial number as well as the available inverters/weather stations (devices) that can be read, and their corresponding bus address (called Unit ID). If all Unit IDs are showing as 255, the inverters need to be configured, please contact your Ardexa account manager. The SMA_sunny_webbox_config.txt
file collects data from SMA inverters that are connected to the WebBox. 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
.
Arguments
Arguments are as follows:
endpoint
. This is either an IP address like192.168.1.15
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 is502
--attempts
. This is an optional parameter, and determines how many times to times to attempt to read an inverter value. Default is1
--delay
. This is the delay in seconds between inverter send and receive commands, AND ifattempts
> 1. Fractions like0.3
can be used. Default is0.05
