The ET112 (for single-phase systems up to 100 A) and the ET340 (for three-phase systems up to 65 A) energy meters are typically used for energy storage systems.
The EM24 is exclusively used for monitoring three-phase systems.
One EM24 type measuring device uses RS485 connection, while the other connects via Ethernet. All ET types connect via RS485.
Their purpose is to measure the total application performance and consumption at the distribution board. Optionally, it can measure the output power of the PV inverter and display the data in the Color Control GX and VRM portal system.
