SMA Sunny Tripower-X 03-20-1000-2-50 – 20 kW 3-Phase Grid-Tied Inverter

SMA Inverter Features and Benefits

Powerful, intelligent and future-ready — This 20 kW three-phase inverter brings commercial-grade performance, flexible system design and smart monitoring/management features into your PV installation. Whether you’re deploying a new rooftop array or upgrading an existing system, the Sunny Tripower X offers a strong combination of yield-enhancing features, safety and connectivity.

Key Features & Benefits

• 20 kW nominal AC output (for the 03-20-1000-2-50 model) in a three-phase configuration, suited to commercial rooftops and mid-size solar arrays. 

• Three independent MPP trackers, enabling flexible string layout and effective utilisation of high-performance modules (including large-format or high-voltage modules). 

• Wide DC input voltage range (up to 1000 V) and high input-current handling, making it compatible with high-power, high-efficiency PV modules and oversizing for greater yield.

• Built-in advanced features such as string-level optimisation (via ShadeFix), I-V curve diagnostics, and full communications (Ethernet/WLAN, Modbus) for remote monitoring and control. 

• Enhanced safety features: DC-disconnect, arc-fault circuit interruption (AFCI), and rapid-shutdown support compliant to SunSpec. 

• Designed for serviceability and integration: the “System Manager” capability allows monitoring/control of up to five inverters (≈150 kVA) from one unit. 

• Compact, lightweight form (approx. 728 × 762 × 266 mm, ~35 kg) simplifies installation, maintenance and handling. 

Why Choose This Inverter?

If you’re aiming for a solar system that demands: fewer connection points, high reliability, future-proof communications/energy-management capability and strong support from a leading brand then the Sunny Tripower-X 20 kW is an excellent choice. It gives you flexibility (for system design and future expansion), strong yield potential, and peace of mind with safety and monitoring built in.

Application & Installation Notes

• Ideal for medium-sized commercial rooftops, light industrial sites, car-ports or retrofit/repowering of existing PV arrays where you want to upgrade to a smarter inverter.

• Make sure your PV string design matches the DC-input specs (voltage/current) of the inverter to optimise performance and safety.

• Given the three MPP trackers, it’s possible to segment modules into different orientations or shading zones while still maintaining performance.

• Ensure your installation team is familiar with the advanced communications and monitoring features (e.g., configuring ethernet/WLAN, setting up the SMA Sunny Portal/ennexOS).

• For best results: choose high-efficiency modules, minimise shading, maintain good ventilation and keep cables/terminals clean and secure.

Warranty & Service

Standard with SMA is a 10-year product warranty for the inverter, with optional extension to 20 years. Component-level diagnostics and proactive monitoring (via SMA Smart Connected) help reduce downtime and service cost.

High Efficiency and Performance

The SMA inverter is designed to deliver exceptional performance in solar energy systems, boasting an impressive efficiency rate that can reach over 98%. This means that you get more out of your solar panels because the inverter minimizes energy loss during the conversion from direct current (DC) to alternating current (AC). It operates effectively across various environmental conditions, so it remains reliable for energy management in both residential and commercial applications. Additionally, the advanced cooling technology ensures optimal performance even in high-temperature settings.

Advanced Monitoring Capabilities

One of the standout features of the SMA inverter is its advanced monitoring capabilities. With the integrated SMA Smart Connect, users can easily monitor their energy production via smartphone or computer in real-time. This flexibility allows users to track system performance, manage energy consumption, and identify issues promptly. Knowing how much energy is generated and consumed not only enhances user satisfaction but also helps in optimizing energy use at home or in businesses.

Durable Design for Longevity

Durability is a key aspect of the SMA inverter's design. It is built to withstand harsh weather conditions, ensuring long-lasting performance even in challenging environments. The inverter's robust build minimizes maintenance needs, so you don't have to worry about frequent repairs or replacements. Additionally, SMA products come with comprehensive warranties, providing peace of mind for consumers investing in sustainable energy solutions. This inverter is not just a purchase; it's an investment in reliable, eco-friendly energy production.
