Scenario With a Smart Array Controller
(2016-06-20)
The general power input cable of the SmartACU2000 smart array controller (smart array
controller for short) needs to be prepared by the customer. Recommended cable: four-core
multi-wire (L1, L2, L3, and GND) armored; operating voltage to the ground: ≥ 600 V; and
cross sectional area of a single core: 4mm
The cable from the busbar to the knife switch needs to be prepared by the customer.
Recommended cable: three-core multi-wire (L1, L2, and L3); operating voltage to the
ground: ≥ 600 V; cross sectional area of a single core: 4 mm
The SmartLogger can be connected to the SUN2000 through an RS485 communications
cable or AC power cable. If the RS485 communications mode is used, no AC power cable
is required between the SmartLogger and the X1 terminal block in the scenario with smart
array controllers; no AC power cable is required between the SmartLogger and the MCB
in the scenario without smart array controllers.
If the SmartLogger uses the RS485 communications mode, it is recommended that at least
two RS485 signal SPDs be installed. A maximum of three RS485 signal SPDs can be
installed for each site.
The smart array controller, also a communication box, is an outdoor cabinet that controls the

communication of the PV array in a PV plant. The cabinet can house components such as the
SmartLogger, RS485 signal SPD, PID module, inductor, ATB, PoE module, and PoE SPD.
The PID module and inductor are configured only in the smart array controller with the PID module

and have been installed before delivery.
