Product Description
INVT LDW-1 DIN-Rail Logger
The INVT LDW-1 DIN-Rail Logger is a solar monitoring data logger designed to collect operating data and power generation information from PV inverters, meters, and other compatible devices. Supporting RS485, RS422, and RS232 interfaces, it enables communication with multiple devices and uploads data to a remote monitoring platform via Wi-Fi or Ethernet.
With support for connecting 1–10 devices, configurable data upload intervals, and remote monitoring capabilities, the LDW-1 helps solar installers and system operators monitor PV system performance, analyze historical data, and improve operation and maintenance efficiency. Its compact design and standard 35 mm DIN-rail mounting make it suitable for solar monitoring installations.
