Overview
2.1 Product Introduction
Features
The smart array controller is an outdoor cabinet that houses the SmartLogger2000
(SmartLogger for short), potential induced degradation (PID) module, power line
communication central controller module (PLC CCO module, in the dual-split transformer
scenario), local area network (LAN) switch, access terminal box (ATB), power over Ethernet
(POE) module, POE surge protective device (SPD), and so on.
The SmartLogger installed in the cabinet collects data from PV devices and reports the data to
the plant monitoring system over a fiber ring network or 4G LTE network to control the
communication between the PV plant and the monitoring system. The SmartLogger that has
the embedded PLC function can connect to a SUN2000 integrated with the PLC function. In
the scenario with a dual-split transformer, use a smart array controller that supports the access
of two PLC routes, that is, the smart array controller that is factory-installed with an
independent PLC CCO module and a SmartLogger with the built-in PLC function.
PV devices include the SUN2000, box-type transformer, video surveillance device, and environmental
monitoring instrument (EMI), and so on.
The smart array controller can be factory-installed with a PID module to prevent PID effect
on PV modules, thereby increasing the energy yield and benefit.
The smart array controller can be installed on a wall, support, or pole. The front door can be
opened for maintenance, which facilitates installation, cable connection, and future
maintenance.
