The SDM230-NMI-2 is a Dual RS485 Din Rail Single Phase Multi-function Solar PV/Zero Export Meter with 50mS data update . The meter measures active energy (kWh), reactive energy(kVArh), current, voltage, power, power factor, frequency, etc. The unit support Max. 100A direct connection.2X RS485 Modbus communication ports are provided for remote monitoring and setting.

The bi-directional measurement, as well as the 50mS data update makes it an ideal choice for solar PV measurement solutions, especially the zero-export solution. The inverter could receive the data from the meter more quickly.

The unit has been approved to meet the requirements of EU Directive 2014/32/EU.
