GoodWe GMK330 Energy Meter Three-Phase with 3 CTs 120 A Class 0.5
The GoodWe GMK330 is GoodWe's residential three-phase smart meter, supplied complete with three current transformers with a 120 A : 40 mA ratio. It is installed on a DIN rail in the distribution board (4 modules) and supports the 1P2W, 3P3W and 3P4W network configurations, with the CT ratio configurable from the app.
It measures power, voltage, current and bidirectional energy at the grid connection point in real time and communicates with the GoodWe inverter via RS485 over up to 1000 m. It is the device that enables load monitoring, self-consumption management and export limitation; the class 0.5 accuracy makes it suitable also for residential systems with high consumption and zero-export systems.
Key features
