The S-Max Series grid-tiered solar inverter from Eaton converts sunlight into ac and is designed for 600 Vdc and three-phase utility interactive operation. Embedded intelligence automates commissioning, operation, and shutdown to reduce physical contact and improve safety. It incorporates NEMA-based visible blade disconnects for ac and dc circuits to enable reliable photovoltaic system interconnection. The solar inverter incorporates programmable logic controllers, variable frequency drives, and protective relays. The 250 kW inverter has active front-end technology, which can operate in harsh environments with 24/7 operation cycles. It has a 96.5% efficiency rating from the California Energy Commission.
