The Sungrow Logger4000 is a high-capacity data logger designed for commercial, industrial, and utility-scale PV systems, as well as larger residential setups with multiple inverters. It supports up to 300 devices, including inverters, meters, and sensors, and connects via RS485 or Ethernet. With built-in digital and analogue I/Os, it can integrate external control signals and sensors, enabling remote monitoring, parameter adjustments, and local maintenance via WLAN or iSolarCloud.
The Logger4000 is ideal for systems needing export limitation, grid support, or battery integration. It makes a strong choice for UK installers working on complex PV or hybrid projects that demand robust monitoring and DNO-ready control.
