Typical System Design and Diagrams
The FlexOM Meter V2 can be connected to an oprtional third-party datalogger/controller
(supplied by others) by connecting an RS485 cable to the AUX port to enable the equivalent of a
direct transmission connection with the daisy chain.
The gateway within the FlexOM Meter V2 can be used as a Modbus/TCP server; to connect to
an optional third-party SCADA system (supplied by others); and to forward various commands
to the daisy chain.
The gateway within the FlexOM Meter V2 allows users to connect different CPS inverter models
and third-party weather sensors (supplied by others) in the same daisy chain via RS485. The
connected hardware must use Modbus RTU protocol at 9600 baud to be compatible with the
CPS portal. Please check with CPS America regarding hardware compatibility prior to
installation and commissioning. CPS hotline (choose option #2): +1 855-584-7168
The FlexOM Meter V2 models must have an Internet connection to enable remote data
communications with the CPS Portal. The FlexOM-4G Meter V2 includes a pre-installed SIM
card and a 5-year 4G cellular plan. The standard FlexOM Meter V2 does not include a pre-in-
stalled SIM card and requires an Internet connection via the Ethernet port.
Page 12
The CPS FA1-X Gateway--included as part of the FlexOM Meter V2
assembly--requires a connection to the Internet using Ethernet. Any LAN
firewall ports must be opened before commissioning the FlexOM Meter
V2.
The following ports must be opened both ways (for incoming and
outgoing communications):
TCP 1884 with destination IP 47.254.52.209
(mqtt.chintpowersystems.com)
Internet interface: Ethernet (FlexOM MeterV2)
Internet interface: 4G (FlexOM-4G Meter V2 only)
The CPS FA1-X Gateway--included as part of the FlexOM-4G Meter V2
assembly--includes a pre-installed SIM card and is compatible with AT&T,
T-mobile, and Verizon networks. The standard 4G cellular data plan period
is 5 years.
After the gateway is powered on, it will automatically select and connect
to the provider network with the strongest or most stable signal.

POWER ON
Before closing the cover of
inverter wire-box or external
DAS box, check again that the
gateway’s power switch is set
to ON.
Pass the SMA end of the
coaxial antenna cable through
the disassembled cable gland
parts in sequence, then tighten
the cable glands again.
Screw one end of the antenna
cable into the cable connector
of the gateway (applicable to
FlexOM-4G model only).
Screw the N-Type end of the coaxial antenna cable
into the antenna.
Mount the 4G antenna as high
as possible on a metallic
structure.
