3. If you encounter the problem of meter communication failure, please check
the meter configuration through the product user manual, communication
address: 1, baud rate: 9600, protocol: 3 (Modbus-RTU).
4. Users need to prepare CT with specifications of xxx / 5A, e.g. 1000A / 5A,
2000A / 5A, etc.. The CT selection should take into account the maximum out-
put current and load current at the inverter paralleling machine, usually select
1.2 to 1.5 times the maximum value, and ensure that the appropriate aperture
size to fit the wire diameter at the paralleling machine.
For example: inverter specifications single maximum output current 200A, par-
allel 5 units, the maximum output current at the parallel 1000A, the maximum
current of the load is 1200A, according to the market common specifications
to choose the appropriate CT, can choose 1500A / 5A specifications of the CT.

Inverter/Meter
It is recommended to use TIA/EIA 568B standard network cable to connect the
Link/RS485-3 of CH1000 to the inverter/meter, one end of the cable is inserted
into the Link/RS485-3 of CH1000, and the other end of the cable will be con-
nected to the RS485A and RS485B of the inverter/meter on the first (white-or-
ange) and second (orange) pins of the cable, respectively. Please see the LINK
port description table for details. See the port description table for details.
