Beside the L and N connections, the power meter must be
connected to the xStorage Home system via the RS-485
communication cable (Figure 7), 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 User Interface (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 7:
•
References 58 and 59 identify the RS-485 connection
terminals;
•
References 47 and 48 identify the pulse terminals (not used
for this product);
•
References 1 and 2 identify the line connection terminals;
•
References 3 and 4 identify the neutral connection terminals.
The hybrid inverter RS-485 port terminals are located in the
communication slot that is highlighted by the arrow pointer in
Figure 8. Please note that up to two devices (in this case,
two power meters) can be connected through the hybrid
inverter’s RS-485 port.
