GoodWe EzMeter GM3000 Energy Meter Three-Phase with 3 CTs 120 A RS485
The GoodWe GM3000 (EzMeter range) is a 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, while the CTs are clamped onto the phase conductors at the grid connection point: the measurement is therefore indirect and does not require breaking into the power lines.
It measures the energy exchanged with the grid bidirectionally and transmits the data to the GoodWe inverter via RS485 over distances of up to 1000 m. It is the component that enables consumption monitoring, self-consumption optimisation and limitation of the power fed into the grid. The compact 2-module DIN format makes it easy to fit even into crowded boards.
