Purpose of this plugin is to read from Huawei Solar Loggers using the Modbus protocol.
Usage
This plugin reads the Huawei Loggers and attached Inverters via Modbus. It uses the Modbus Specification and collects from IP connected inverters using TCP protocol. Inverter data will be collected to the solar table. There are a number of files that can be used to query the Huawei loggers depending on the version of the logger and the attached inverters. The huawei_sun2000.txt (default) file collects data for the Huawei 2000 logger. The other files are huawei_sun2000_60ktlhuawei_sun2000_ktl.txthuawei_sl1000.txthuawei_sl3000.txt and huawei_logger_inverters.txt. Please ensure the file collects the data suitable for your logger.
The following Huawei SmartLogger models are supported:
SL1000 SL3000
The huawei_sun2000.txt config file is valid for the following inverter models:
Other inverter models have their own dedicated configuration file.
For newer firmware versions of the same models, use the huawei_sun2000_v2.txt file as it has a Warning field and different scaling factors.
These should be read using the huawei_smart_logger.txt config file. The huawei_sl1000.txt and huawei_sl3000.txt config files are old and included for backwards compatibility. They are functionally identical and the same as the huawei_smart_logger.cmd.
Data will be run every 5 minutes by default. This plugin relies on the Modbus Ardexa plugin. The following data will be collected for the huawei_sun2000.txt file. For the other files contact Ardexa. Please also note that this plugin will ONLY collect data from TCP (not RS485 lines).
Run a log to send data to the cloud or a discover to only display information. You may need to configure the Huawei Logger for Modbus collection as follows:
1. Configure Settings->Modbus TCP
a. If the Ardexa machine has a static address enable "Link Setting: Enable(Limited)" and
b. Add the IP address of the Ardexa device. If the Ardexa device is DHCP then make sure the "Link Setting: Enable(Unlimited)""
2. Address mode: Logical Address
3. SmartLogger address (0-247): 1
Huawei Logger Data
The following logger data will be collected to the solar table for the huawei_smart_logger.txt file. This is the same list of data that is collected from the huawei_sl1000.txt and huawei_sl3000.txt config files.

Arguments
Arguments are as follows:
endpoint. This is either an IP address like 192.168.1.15
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 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
--timeout. This is the modbus command timeout in milliseconds. Default is 1000. This is only the timeout value in event of the modbus server not responding. If a modbus server responds sooner, then this value is ignored.
--socket_delay. Some Huawei equipment needs a delay between establishing a TCP socket and getting data. This feature allows this delay. It is defined in milliseconds.
