What Sensors are Typically Included in a Huawei Weather Station Setup?

If you’re using Huawei SmartLogger1000, SmartLogger3000, etc. and want weather data you can actually use for PV performance analysis, this weather station setup is built around a simple idea: measure the site conditions that directly explain energy yield (irradiance, temperatures, wind) and send them to Huawei via RS485 Modbus RTU.

The standard sensors used for the Huawei weather station are as follows:

• Irradiance Sensor (PV Pyranometer / Reference Cell)
  Measures solar irradiance (radiation). This PV pyranometer is crucial for solar applications. The SEVEN irradiance sensor is designed as a sensor box and includes an internal cell temperature sensor to provide a compensated irradiance value. It also has up to four input ports for additional sensors, and an RS485 output port for connection to the Huawei SmartLogger.
• Ambient Temperature Sensor
  Important for understanding how production is affected by temperature. Since PV module temperature can vary significantly from ambient temperature, this sensor provides valuable data for PV plant analysis.
• Module Temperature Sensor
  Typically used to measure surface temperature. It is installed on the back of the PV panel and provides module temperature data. Monitoring module temperature is important, as it is one of the factors used to calculate the Performance Ratio (PR).
• Wind Speed Sensor
  Measures wind speed and transmits the data to the Huawei SmartLogger.
• Wind Direction Sensor
  Used to determine wind direction (orientation of the wind).

In addition, other sensors can be connected to the SEVEN irradiance sensor box, such as a humidity sensor, which measures relative humidity in a photovoltaic plant.

We support customers globally with shipping options based on destination and project needs. If you’d like assistance beyond hardware delivery, our engineers can also help with commissioning and verification (including remote support after installation).

How Does the Sensors Help Monitor Performance Ratio (PR) in Huawei?

Once sensors are connected to the Huawei SmartLogger, the monitoring workflow typically runs through Enspire and then into NetEco or FusionSolar. With irradiance and temperature data available, PR and related performance metrics become much easier to interpret because you can compare plant output against the actual on-site conditions.

A simple real-world example:

• If energy drops but irradiance also drops → it’s likely weather-driven.
• If irradiance is stable but energy drops → you have a stronger signal to investigate (soiling, inverter behavior, shading, string issues, etc.).

How Does the Sensor Connect to Huawei SmartLogger?

The weather station communicates with SmartLogger using RS485 and Modbus RTU.
A typical wiring approach is:

• RS485 A / Data (+), RS485 B / Data (–), and RS485 Data Ground connected to a SmartLogger COM port
• The sensor box is powered via DC Supply. The sensors can be powered between 12–30 VDC, with 24 VDC recommended

How do you Commission Sensors into Huawei System?

For full details, please refer to our step-by-step guide and the commissioning video. Here’s a brief overview of the process:

1. Install and mount the sensors at the PV plant according to the recommended placement guidelines described in our user manual.
2. Connect the RS485 communication lines and power wiring to the Huawei SmartLogger and an appropriate power supply.
3. In Enspire, configure the RS485 communication parameters (e.g., baud rate, parity, device address) and add the Sensor box as a device.
4. Configure the parameters to be monitored using the register addresses provided in our Modbus maps.
5. Verify the live measurements in the SmartLogger Running Info, then confirm that the data is successfully visible in FusionSolar / NetEco.

If you prefer, our engineers can support the setup remotely after installation.
