SmartACU2000D Smart Array Control Unit

Product Description

The SmartACU2000D is a pre-assembled outdoor smart array control unit solution designed to simplify the communication infrastructure of utility-scale PV plants. By integrating multiple core devices into an IP65 protection enclosure, it reduces on-site installation and wiring time while ensuring uninterrupted data transmission to the dispatch center.

Key features

• One-Click Smart Setup: Built-in SmartLogger3000B supports the simultaneous connection of up to 200 devices, enabling fast parameter configuration and system-wide identification.

• High-Speed Dual MBUS Communication: Optional integration of up to 2 MBUS modules collects data directly from inverters via AC power cables (supporting voltages from 380V to 800V), eliminating RS485 communication cabling costs and workload.

• Anti-PID Module (SmartPID2000): Supports pre-installation of 1 to 2 SmartPID2000 modules. This module actively injects a compensation voltage to recover and prevent Potential Induced Degradation (PID) effects on PV modules.

• Robust Optical Switching: Equipped with an industrial-grade network switch featuring 4 SFP fiber ports and 8 100/1000 Mbps Ethernet ports, enabling a highly stable fiber ring topology between equipment stations.

• Durable Outdoor Operation: The entire system is protected within an IP65 enclosure, operating reliably across an industrial temperature range from -40°C to +60°C.

Why Choose the SmartACU2000D?

• Pre-Assembled All-in-One Design: SmartLogger3000B, SmartPID2000, and the network switch are pre-installed, wired, and factory-tested, minimizing on-site technical risks.

• Convenient Front Maintenance: Front-opening door design allows technicians easy access for inspection and maintenance of internal components.

• Convenient Front Maintenance: Front-opening door design allows technicians easy access for inspection and maintenance of internal components.
