Controlador de potência PV para OSD via protocolo SunSpec

The PV Power Control Device for OSD via SunSpec Protocol is a bi-directional energy meter designed for dynamic power control of photovoltaic installations. It enables grid operators (OSD) to manage feed-in power using the SunSpec protocol, ensuring compliance with grid regulations. This 3-phase meter measures energy import/export, power, voltage, current, frequency, and power factor with Class 1 accuracy. It communicates via Modbus RTU (RS485) and is compatible with Fronius Symo, Primo, and Gen24 Plus inverters. The device mounts on a DIN rail (4 modules) and features an LCD display. Its self-extinguishing thermoplastic housing and IP51 protection make it suitable for indoor use.

Advantages
