SmartLogger 3000A monitors and manages photovoltaic installations. It connects all ports, converts protocols, collects and stores data, and centrally monitors and maintains equipment in PV installations. The SmartLogger can be networked with other PV systems over distances of up to 12 km via fiber optic cable. The Huawei SmartLogger 3000A is a data logger that can be connected to up to 200 devices, 150 of which can be inverters. This provides insight into the performance of photovoltaic panels and inverters. Thanks to its handy size and relatively light weight, it is easy to install. The device can be accessed, for example, via the Internet (WAN), but also via local area network (LAN), RS485, MBUS, mobile networks (2G/3G/4G) and digital and analog inputs and outputs. There are also three LEDs on site for reading statuses. There is also an integrated web portal for system configuration. Commissioning can also be done via WLAN using an app. The SmartLogger also features a USB2.0 port.
