Product Description
General
AGF-T Perforation type PV confluence acquisition device is specially designed for smart PV combiner box. It is used for monitoring the running state of solar panels in solar cell arrays, measuring the currents of solar cell, detecting the state of surge protection devices and DC breaker. The device is equipped with RS485(Modbus) communication port for transmitting all the datas to master device.
Coding Rule
Characteristics
◆ Primary current is connected in through perforation. Easy installation, high safety.
◆ With Hall sensor, the max isolation measuring current 20A
◆ Voltage measurement range for Bus bar is up to DC1.5kV
◆ LED display, fit for checking and testing operation in wide-temperature or outside environment.
◆ With the function of inner temperature measurement for real-time measurement of the inner
temperature of combiner box
◆ With RS485 Modbus RTU
◆ More options of power supply
◆ Compatible with din rail installation and baseboard fixation installation, small dimension saving more
box space.
Main Function
◆ Photovoltaic cell open circuit alarm to cooperate with group string voltage and judge Comprehensively
◆ With 3-channel switching state monitoring to collect output idle contact information of DC breaker 、lightning protector. protector etc
◆ Option RS485 port, Modbus-RTU protocol; programmable slave address, baud rate, data format
◆ English LCD display，convenient to set parameters and check the data
Technical Parameters

Power supply module size(Figure 1)
Note: Imaginary line is the fixing size of the bottom plate
As power supply module is heavy, bottom plate is needed in installation to avoid its coming off during
transportation.
Confluence acquisition module installation dimension
8-channel confluence acquisition module installation dimension(Figure 2)
4-channel confluence acquisition module installation dimension(Figure 3)
Configuration of 8-channel or 4-channel confluence acquisition module will be decided by actual needs:
when 4 channels or less are needed, 4-channel confluence acquisition module will be installed, when
needed channel number is 5 to 8, 8-channel confluence acquisition module will be installed. When needed
channel number is more than 8, then the number will be divided by 8. If there is a remainder in the result
and the remainder is less than 4, then 4-channel confluence acquisition module will be installed. If the
remainder is more than 4, 8-channel confluence acquisition module will be installed.

Connections of modules
Data cable connection way
The connection between each module is through the external data line. Please confirm the
sequence of the two external data line ports before connecting each module. Each confluence
acquisition module has two outside connection ports(Figure 4): Port I and Port II, in which Port I is used
to connect upstream module and Port II is used to connect follow-up modules. Please pay attention to it
that the propulsion part of the data line connector must be fixed with the groove on the port.
The connection sequence order of PV confluence acquisition modules must follow: confluence
acquisition module 1’s port Ⅱ-->confluence acquisition module 2’s port Ⅰ ,
confluence acquisition module 2’s port Ⅱ-->confluence acquisition module 3’s port Ⅰ .
When connecting the confluence acquisition modules ,multiple confluence modules should be in
sequence order, it is not allowed to insert any other function module between two sequenced confluence
modules. Wrong connection will lead to abnormal operation of the device.
LCD display module can be connected with Port II of confluence acquisition module, The LCD
display module is not necessary to be connected in at ordinary time except when testing and checking.
The address allocation of PV confluence acquisition module is automatically distributed by the
power module(main module), The first confluence acquisition module connected to the power module
will be distributed automatically with 1st to 8th channels, and the next confluence acquisition module
connected to port II will be distributed automatically with 9th to 16th channels, the final confluence
acquisition module is distributed automatically with 17th to 24th channel.
Installation schematic
Note: The arrow shows current direction. Wrong connection will lead to abnormal operation of the device.
Definition of input port
After the address of confluence acquisition module is distributed by the main module，the input
channel address of first module is from 1st to 8th channel，the input channel address of second
confluence acquisition module is from 9th to 16th channel，the input channel address of final confluence
acquisition module is from 17th to 24th channel. The input channel definition of 1st to 8th channel of a
single module is shown as Figure 3.
