8.4.2 EPO Connection
Generally, EPO is connected to backup interface to simultaneously command the
whole system to become idle and enter a safe mode. While EVERVOLT Hybrid
series inverter can be wired to include an emergency stop switch as well. EPO
connects to inverter only if no backup interface is equipped. Please refer to
“Appendix EPO Connection Steps” for more details.B
8.4.4 External Electricity Meter (Meter Y) Connection (Optional)
The RGM(Meter X) isusedto get the information about the energy flow. If the
Meter X has been purchased from Panasonic, it will be pre-mounted inside the inverter
before leaving factory.
8.4.3 RGM (Meter X) Connection (Optional)
The external electricity meter (Meter Y) will be integrated in the Smart Box if
Meter Y has been purchased from Panasonic. It connects to inverter only if no Smart
Box is equipped in the whole system. Please refer to “Appe Meter Y ndix C
Connection Diagram” for more details about meter connection on the inverter.
8.4.5 RSD Transmitter Connection
The APsmart Rapid Shutdown System Transmitter-PLC-1P is part of a rapid
shutdown solution when paired with APsmart signal receiver (RSD-S-PLC-A,
RSD-D15-1000 or RSD-D-25-1000), a PV module rapid shutdown unit.
While powered on, the Transmitter-PLC-1P sends a signal to the signal
receiver to keep their PV modules connected and supplying energy. The
signal receiver automatically enter rapid shutdown mode when the
Transmitter-PLC-1P is switched off and resume energy production when
power is restored to the Transmitter PLC-1P. This solution complies with
NEC 690.12 specifications for 2017&2020 and supports the SunSpec signal
for rapid shutdown.
NOTE!
The RSD has been integrated in the inverter before leaving factory.
NOTE!
If an emergency stop switch is required, the customer needs to
purchase and wire it.

EVERVOLT Hybrid inverter same-power inverters support up to 4 parallel
connection, Unified EMS management function by the primary machine. The
primary and secondary machines are interconnected via CAN and RS485
buses.
For detailed diagram, please see Appendix D: System Wiring Diagram. Refer to
8.4.6 Parallel Connection
1) All parallel solutions must be equipped with EV-SB as standard, and
EVERVOLT Hybrid inverter AC direct parallel external power meter solution is
not supported.
2) The EMS under grid parallel can support the same modes as the stand-
alone EMS mode, including:
Ÿ Self-Use (default)
Ÿ Backup mode
Ÿ Time of Use mode
Ÿ Feed in Priority
Ÿ Demand mode
Ÿ Constant power discharge mode
Concurrent Primary-Secondary role setting
1) All machines need to set parallel enable/ disable. Enabling parallel
machine does not allow running standalone mode.
2) The Primary also needs to set the number of parallel machines.
3) Primary communication lost, system down waiting for human intervention
to recover.
4) Loss of Secondary communication (CAN), the primary operates normally,
but reports a "Loss of Secondary Communication Alarm". The lost Secondary
stops and reports a parallel communication failure until the communication is
restored and then tries to integrate into the system again.
For details, please refer to “Parallel Connection Guide”.
the detailed communication connection diagram (p. 75) for communication
wiring between parallel inverters.
