Fronius Symo Advanced 15.0-3 480 Lite 15kW Three-Phase Inverter

About This Product

The Fronius Symo Advanced 15.0-3 480 Lite 15kW Three-Phase Inverter is a commercial grid-tied solar string inverter designed for US three-phase electrical systems operating at 480V AC. Part of the Fronius Symo Advanced family, this model converts DC power from solar panels into grid-compatible AC electricity for commercial solar installations.

The inverter features an integrated power line communication (PLC) transmitter supporting the SunSpec Rapid Shutdown communication standard. This simplifies integration with compatible module-level rapid shutdown equipment where required by the National Electrical Code (NEC). Its transformerless design, flexible mounting options, and field-serviceable construction make it suitable for professional commercial PV installations.

Who This Product Suits

This Fronius inverter is suited to commercial solar projects requiring a three-phase, 480V grid-connected inverter. Typical applications include offices, warehouses, workshops, agricultural facilities, and other commercial buildings with compatible electrical infrastructure.

It is particularly useful for installers designing systems in jurisdictions with module-level rapid shutdown requirements. The integrated SunSpec PLC transmitter supports communication with compatible rapid shutdown devices, reducing the need for a separate transmitter in appropriately designed systems.

Installation should be completed by a qualified solar electrician familiar with commercial three-phase systems, utility interconnection requirements, and applicable NEC provisions.
