The SMA Energy Emeter-20 bi-directional energy meter is a powerful metering solution for intelligent energy management in photovoltaic systems with SMA devices. The SMA Energy Meter determines phase-accurate and cumulative electrical measurement values and communicates them via Ethernet on the local network. In this way, all data on the electricity fed back into the grid and purchased or also PV generation from other PV inverters can be transmitted to the SMA systems with high accuracy and frequency. The combination with the SMA energy meter provides a perfectly coordinated system configuration that ensures the highest efficiency and stability, as well as the best savings and increased self-consumption.
