Huawei SmartLogger 3000A01EU (This is a product name and does not require translation; it is the same in both Italian and Engli
The Huawei SmartLogger 3000A01EU is the professional data logger for centralized monitoring of photovoltaic systems with up to 80 devices (SUN2000 inverters, sensors, LUNA2000 batteries). It features 4G connectivity, Ethernet WAN/LAN, and 3 RS485 ports, Modbus-TCP and IEC 60870-5-104 protocols, integrated web server, and zero-export function. Can be wall-mounted, DIN rail-mounted, or used on a desktop. Version without PLC/MBUS module: for the version with PLC, see SmartLogger 3000A03EU.
The Huawei SmartLogger 3000A01EU is the data acquisition and centralized management system designed by Huawei for medium and large photovoltaic plants. Compatible with the FusionSolar ecosystem, it enables real-time monitoring, remote diagnostics, and advanced control of production for up to 80 connected devices, including SUN2000 inverters, LUNA2000 batteries, SmartGuard, and power sensors.
Why choose SmartLogger 3000A01EU?
In a photovoltaic system with multiple inverters, the data logger is the collection point for all production data and the tool through which power injection into the grid is managed. The SmartLogger 3000A01EU offers multiple connectivity (4G, Ethernet, RS485), an integrated web server accessible from any browser without additional software, and native support for the zero-export function (limiting grid injection), a requirement increasingly requested by Italian electricity distributors. Configuration is done via the Huawei FusionSolar app over Wi-Fi, with no need for a notebook on site.

Difference between SmartLogger 3000A01EU and 3000A03EU
Both models support up to 80 devices and share the same physical interfaces, but differ in the PLC communication module: the A01EU version does not include the PLC/MBUS module, which is necessary for connecting to inverters via powerline (existing electrical wiring). The A03EU version includes the PLC module and is recommended for systems where it is not possible to lay RS485 cables between the logger and the inverters. If the inverters can be reached via RS485 or Ethernet, the A01EU version is sufficient and generally less expensive.

Frequently Asked Questions
How many inverters can the SmartLogger 3000A01EU manage?
The SmartLogger 3000A01EU manages up to 80 connected devices, including Huawei SUN2000 inverters, LUNA2000 batteries, SmartGuard, and power sensors. You can connect up to 30 devices to each of the 3 RS485 COM ports. For larger systems, the SmartLogger 3000B is available, supporting up to 150 devices.
Does the SmartLogger 3000A01EU support the zero-export function?
Yes. The SmartLogger 3000A01EU includes an intelligent zero-export control system that automatically regulates inverter power to prevent grid injection. This function is required by many Italian distributors (e.g., E-Distribuzione) for systems without unlimited net metering authorization. To activate it, an energy meter must be connected to the logger’s AI/DI ports.
How is the SmartLogger 3000A01EU commissioned?
Configuration is done via the Huawei FusionSolar app, available for iOS and Android, by connecting to the logger via Wi-Fi. Alternatively, you can use a notebook connected to the LAN port. The guided procedure in the app automatically detects inverters connected via RS485 and completes commissioning in a few minutes without additional software.
Do I need the A01EU or the A03EU version with PLC?
If the SUN2000 inverters can be reached via RS485 cable (distance less than 1000m) or Ethernet, the A01EU version is sufficient. The A03EU version with PLC module is only needed when it is not possible to lay RS485 cables and you want to use the existing electrical wiring as a communication channel (powerline). For residential and commercial systems with dedicated wiring, A01EU is the correct and more economical choice.
Is the SmartLogger 3000A01EU compatible with FusionSolar cloud?
Yes. The SmartLogger 3000A01EU integrates natively with Huawei’s FusionSolar cloud platform, accessible via browser and mobile app. Once connected via 4G or Ethernet WAN, it automatically sends production data to the cloud, enabling remote monitoring of the system, alarm management, and generation of production reports.
