PV Plants Connecting to SmartPVMS Quick Guide (Inverters
• Before site deployment, ensure that the inverters and SmartLogger are powered on and the communication is normal. • Ensure that you have matched the devices in a PV
This integration supports two connection modes to your Huawei Solar installation: If your installation contains multiple inverters and a battery, the SDongle seems to regulate a part of how the inverters and battery interact. Removing the SDongle will degrade your installations performance.
Huawei Solar Tools is a Python library for interacting with Huawei solar inverters, batteries, power meters, and energy management interfaces (EMI) using Modbus TCP. It provides methods to read and write Modbus registers, retrieve operational data, and interpret register values. Establishes Modbus TCP communication with Huawei solar devices.
When the dongle is unable to ping the default gateway or connect to the Huawei FusionSolar cloud (for example due to a service or network outage), it will periodically restart in an attempt to restore connectivity. This will also interrupt the connection to this integration.
If your inverter has such a dongle installed you cannot use a serial connection option. We recommend connecting to the Modbus-TCP port exposed by that dongle instead. To use the direct serial connection, you need an "USB to RS485 converter".
