The Goodwe GMK330 is a three-phase DIN-rail smart meter designed to pair with Goodwe hybrid and grid-tie inverters for accurate consumption monitoring, export power limiting, and zero-feed control. It ships with three 120 A split-core current transformers and supports any common grid topology (1P2W, 3P3W, 3P4W) with a wide 90 to 264 V input window. Class 0.5 accuracy and a 1000 m RS485 link make it suitable for both residential and small commercial PV sites where the inverter and switchboard are some distance apart.
