The GoodWe GMK330 is a three-phase smart meter for GoodWe inverter systems. It can be used for local consumption measurement, load monitoring, export limitation, and zero-feed applications.

The GMK330 operates with external current transformers (CTs), and according to the documentation, it includes 3 CTs. The newer design uses a unified 120A:40mA current transformer; the previous 200A:50mA version will be phased out after June 2026, according to the manufacturer's note.

The meter supports 1P2W, 3P3W, and 3P4W network types. It connects to the inverter via RS485 communication, with a maximum communication distance of 1000 meters. The accuracy class for voltage, current, and active energy is Class 0.5.
