 The Eastron SDM230-Modbus MID 1-phase kWh meter is ideal for the precise monitoring of, for example, a solar panel system, a charging station, a heat pump or another 1-phase group of your choice. On the illuminated LCD screen, you can immediately see how many kWh the respective system consumes or produces and is used for official registration and billing of the measurement data. For example, if you want to bill a tenant for the electricity consumption of a specific room. The Eastron SDM230-Modbus MID 1-phase kWh meter is ideal for the precise monitoring of, for example, a solar panel system, a charging station, a heat pump or another 1-phase group of your choice.
