Description
The Huawei SmartLogger 1000A Data Logger is an industrial-grade, high-capacity telemetry data logger engineered to monitor, manage, and coordinate commercial photovoltaic (PV) solar arrays and power storage systems. Operating as the central brain of a power plant, it aggregates data across multi-brand inverters, smart meters, weather stations, and sensors over Modbus protocols, linking local field hardware directly to the Huawei FusionSolar enterprise cloud monitoring platform.
 This advanced data monitoring gateway is explicitly designed for:
-
Commercial & Industrial (C&I) Solar Installers: Technicians who need a reliable, rugged hub to manage complex, multi-inverter utility grids.
-
Solar O&M (Operations & Maintenance) Teams: Asset managers requiring real-time diagnostic performance data, remote firmware updates, and rapid fault pinpointing.
-
Grid Infrastructure Engineers: Professionals building automated power plants that must comply with strict national grid regulation controls and zero-export limitations.
Key Features
-
Massive 80-Device Connection Capacity: Manages up to 80 downstream electronic devices simultaneously over its independent physical communication buses.
-
Flexible Communication Protocols: Supports a wide array of interface links, including multiple RS485 channels, Fast Ethernet (RJ45), and integrated 2G/3G/4G cellular telemetry.
-
AI-Ready Smart Power Grid Control: Features active active/reactive power regulation alongside power factor correction to meet dynamic utility grid rules.
-
Industrial Multi-Port Interface Layout: Equipped with dedicated digital inputs, digital outputs, and analog inputs to seamlessly link external pyranometers, wind sensors, and RTD temperature probes.
-
Graphic Web User Interface: Built-in web server enables immediate on-site configuration via a standard internet browser without requiring specialized configuration software.
