The required measuring transformers with 5 A secondary current must be ordered separately.
Compatible only with the ET 15-50 series.
The regular GM3000 Smart Meter from Goodwe has 120A primary current and a maximum line diameter of 16mm per converter. If larger values are required due to the system, the new GM330 is used. With this smart meter, all commercially available measuring transformers can be used thanks to its 5 ampere secondary current. High currents and large cable or rail cross-sections are no longer a problem. It replaces the previous GM3000C with expanded functionality and a higher accuracy class. It is only compatible with the large ET series from 15 to 29.9 kW.
