Carlo Gavazzi Unveils Modular Controller For PV Plants


Carlo Gavazzi's automation components business unit has released Eos-Array, a new management and control system targeting small to medium or high-power solar photovoltaic plants.

Easy to install and configure, the Eos-Array comprises individual modular elements that, when interacting with one another, provide a complete and independent control solution that gathers accurate and dependable data to ensure effective information management, the company explains.

The core component is the VMU-M, which performs local bus management of measuring units and I/O modules. The VMU-M assigns the proper local unit address automatically and gathers all local measurements from the VMUaEUR'S and VMUaEUR'P, simultaneously connecting with the external world through VMU-O modules.

The Eos-Array has a modular design, allowing the control to be scaled up or down according to requirements and budgets. A single master VMU-M can control 15 Eos modules on its local bus, including up to seven VMU-O I/O modules and one VMU-P unit.

With no auxiliary bus wiring, the system is simple to install and straightforward to expand, the company says. Further cost saving is provided by the integrated string fuse protection, and modularity improves overall system reliability. String efficiency and inverters are controlled locally, enabling operators to quickly isolate faults, failures and inefficiencies.
