GoodWe GM330 Energy Meter Three-Phase with CT Class 0.5 RS485
The GoodWe GM330 is a three-phase smart meter for photovoltaic and storage systems, to be installed on a DIN rail in the distribution board at the grid connection point. It supports the 1P2W, 3P3W and 3P4W network configurations and works with indirect measurement through current transformers with a 5 A secondary and an adjustable ratio: this makes it suitable for high-power commercial systems as well.
It measures power, current, voltage and bidirectional energy in real time and communicates with the GoodWe inverter via RS485 over distances of up to 1000 m. It is the device that enables load monitoring, self-consumption management and export limitation (export power management). The class 0.5 accuracy on voltage, current and active energy ensures reliable measurements even at low power levels.
Key features
Accuracy class 0.5Class 0.5 accuracy on voltage, current and active energy, better than the class 1 of standard meters.
Measurement with 5 A CTsWorks with current transformers with a 5 A secondary, with a configurable ratio to suit the size of the system.
1P2W, 3P3W and 3P4W networksCompatible with single-phase systems, three-phase systems without neutral and three-phase systems with neutral.
RS485 up to 1000 mSerial communication with the GoodWe inverter even at a long distance from the metering board.
Export managementAllows control of the power exported to the grid and real-time load monitoring.
Wide temperature rangeGuaranteed operation from -30 °C to +70 °C, with 4 status LEDs and a reset button.
