SMA Sunny Tripower X 30-US-50 30kW Three-Phase Inverter

About This Product

The SMA Sunny Tripower X 30-US-50 30kW Three-Phase Inverter is a commercial grid-tied solar inverter designed for three-phase photovoltaic installations operating on 480V AC electrical systems. Part of SMA’s Sunny Tripower X family, this model converts DC electricity from solar panels into grid-compatible AC power for commercial solar applications.

The inverter includes integrated arc-fault circuit interruption (AFCI), a DC disconnect, and a SunSpec-certified rapid shutdown transmitter. These features support system protection, service isolation, and integration with compatible rapid shutdown equipment for installations designed to meet applicable NEC requirements.

Designed for professional installation, the Sunny Tripower X 30-US-50 provides a practical solution for commercial rooftop and other three-phase grid-connected solar projects.

Who This Product Suits

The SMA Sunny Tripower X 30-US-50 is suited to commercial solar installations requiring a dedicated three-phase grid-tied inverter.

• Commercial buildings: Offices, warehouses, retail facilities, and other properties with compatible 480V three-phase electrical service.
• Commercial rooftop solar: PV systems requiring a 30kW inverter with integrated DC isolation and arc-fault protection.
• Professional solar contractors: Installers designing grid-connected systems around NEC requirements, utility interconnection rules, and compatible rapid shutdown equipment.
• Business solar projects: Facilities looking to offset grid electricity consumption through on-site solar generation.

This SMA model is intended for grid-connected three-phase applications rather than standalone off-grid or battery-hybrid operation.
