It enables real-time measurement of voltage, current and
power. These monitored values are shown on the LCD panel
at the front (Figure 13).
The referenced numbers in Figure 13 identify:
1. the LCD display interface;
2. the energy pulse indication light;
3. the menu navigation keys;
4. the model number.

The front and side view [mm] dimensions of the meter are
as shown below:
The DIN rail mount construction enables the power meter to be
installed in a compact electrical distribution box (Figure 15).
During the installation of the power meter, no additional
protective devices are required. The meter connection terminals
must be directly connected to the L1, L2, L3 (lines) and
N (neutral) wires (Figure 16). L1, L2, L3 and N (left side in
the diagram) is the side connected to the xStorage Home
inverter AC output. The arrow (right side in the diagram) is
the side connected to the grid side.
Beside the L1, L2, L3 and N (optional) connections, the power
meter must be connected to the xStorage Home system
via the RS-485 communication cable (Figure 17), to enable
real-time input of the monitored data into the xStorage Home
system. This is possible through the RS-485 port. Data
sent through this port is utilized by the xStorage Home UI
to record the event history and to display the current energy
consumption of both the critical and non-critical loads, as well
as to track the PV-generated energy (as applicable).
The general wiring of the power meter is illustrated in
Figure 17:
