30kW Commercial Solar Power with 480V Three-Phase Output

The SMA Sunny Tripower X 30-US-50 converts electricity generated by photovoltaic panels into grid-synchronized three-phase AC power for compatible commercial electrical systems.

With 30,000W of nominal AC output and a maximum apparent power rating of 30,000VA, this inverter is designed for commercial solar projects requiring reliable energy conversion and advanced grid-management capabilities.

AC Performance

• 30,000W nominal AC output power.
• 30,000VA maximum apparent power.
• 277/480V nominal three-phase AC connection.
• 36A maximum output current.
• 60Hz nominal grid frequency.
• 98% CEC efficiency.
• Less than 3% total harmonic distortion.

Three Independent MPPT Trackers for Flexible Solar Array Design

The Sunny Tripower X 30kW features three independent maximum power point trackers, each with two DC string inputs.

This configuration allows installers to design arrays across different roof sections and orientations while maintaining independent MPPT operation.

DC Input Specifications

• Maximum PV array power: 45,000Wp.
• Maximum DC input voltage: 1,000V.
• MPPT voltage range: 515–800V.
• Minimum input voltage: 150V.
• Initial input voltage: 188V.
• Independent MPPT trackers: 3.
• String inputs per tracker: 2.
• Maximum operating current per MPPT: 24A.
• Maximum short-circuit current per MPPT: 37.5A.

Final PV string sizing must account for module electrical characteristics, temperature-adjusted voltage, input current limits and the inverter's operating requirements.

SMA ShadeFix String-Level Optimization

SMA ShadeFix is an integrated optimization technology designed to help improve energy production when portions of a solar array experience shading.

Unlike systems that require an optimizer on every solar panel, SMA ShadeFix operates at the inverter's string level.

Benefits of SMA ShadeFix

• Helps reduce energy losses caused by partial shading.
• Supports efficient operation across multiple PV strings.
• Works with the inverter's three independent MPPT trackers.
• Reduces the need for additional module-level optimization hardware in suitable designs.
• Supports flexible commercial rooftop array layouts.

Actual energy gains depend on shading conditions, array configuration and system design.

Integrated System Manager for Commercial Solar Control

The Sunny Tripower X includes SMA's integrated System Manager, providing centralized monitoring, commissioning and control capabilities for compatible commercial solar installations.

Instead of requiring a separate external management device for every installation, the integrated System Manager can coordinate multiple supported inverters through SMA's ennexOS platform.

System Manager Capabilities

• Monitor and control up to five compatible inverters.
• Support up to 150kVA of total nominal inverter power.
• Integrate one supported energy meter.
• Centralize commissioning of connected devices.
• Access compatible devices remotely through Sunny Portal powered by ennexOS.
• Support optional SMA Dynamic Power Control functionality.

SMA Dynamic Power Control supports functions such as zero export and Volt-VAr control when appropriately configured. Availability and system requirements should be confirmed for the installation.

Integrated Rapid Shutdown and Arc-Fault Protection

The Sunny Tripower X 30-US-50 incorporates several electrical safety features designed for commercial photovoltaic installations.

Integrated Safety Features

• SunSpec PLC signaling: Integrated communication for compatible module-level rapid shutdown devices.
