The ET112 (for single-phase systems up to 1 A) and ET34 (for three-phase systems up to 65 A) meters are typically used for energy storage systems.
The EM24 is used exclusively for monitoring three-phase systems.
One of the EM24 meters uses the RS485 connection, while the other connects via Ethernet. All ET models connect via RS485.
They are intended to measure the power and consumption of the entire application at the distribution cabinet. Possibly measuring the output power of the PV inverter and displaying the data in the Color Control GX and VRM portal system.
