SMA Sunny Tripower CORE1 50.0 kW 3-Phase Inverter
Model STP50-US-41 | 6 MPPT | 98.1% Efficiency | IP65/NEMA 4X | 10-Year Warranty
Product Overview
The SMA Sunny Tripower CORE1 50.0 kW 3-Phase Inverter (Model STP50-US-41) is a commercial-grade, free-standing inverter designed for rooftops, carports, ground-mounted systems, and repowering legacy installations. Delivering up to 50 kW AC output and supporting PV arrays up to 75 kWp, the CORE1 enables DC oversizing up to 150% for maximum energy harvest and system flexibility.
Key Benefits
Six Independent MPPT Channels: Features six independent MPPT channels with two strings each, maximizing energy harvest in shaded or complex array layouts for optimal system performance.
High DC Oversizing Capability: Supports PV arrays up to 75 kWp with DC oversizing up to 150%, enabling greater energy production and system design flexibility.
Peak Efficiency of 98.1%: Delivers industry-leading efficiency with active OptiCool cooling technology for long-term reliability and maximum energy conversion.
Comprehensive Safety Features: Includes integrated DC and AC disconnects, UL 1699B arc-fault circuit protection (AFCI), and SunSpec PLC rapid shutdown compliance for safe operation.
Advanced Connectivity: Built-in Wi-Fi, Ethernet, RS-485, and Smart Inverter Screen with QR-code access simplify commissioning and monitoring. Compatible with ennexOS and Modbus protocols.
How It Works
The Sunny Tripower CORE1 converts DC power from solar panels into grid-compliant AC power with exceptional efficiency. Its free-standing design and advanced features make it ideal for commercial solar installations.
ShadeFix Optimization: Integrated ShadeFix technology continuously optimizes energy harvest even under partial shading conditions, maximizing system output throughout the day.
SMA Smart Connected: Remote monitoring service provides proactive system oversight, enabling quick identification and resolution of performance issues for maximum uptime.
OptiCool Active Cooling: Advanced thermal management system maintains optimal operating temperatures with silent operation below 65 dB(A), ensuring reliability across a wide temperature range.
