SMA Sunny Tripower 125 (STP125-70)

The SMA Sunny Tripower 125 (STP125-70) is a powerful string inverter, specifically designed for large-scale commercial and utility projects. This device efficiently converts the DC power generated by a larger PV system into AC power and is optimised for maximum yield in complex project environments.

Key Features

• Nominal AC power of 125 kW: Highly suitable for large PV systems.
• 12 independent MPP trackers: Offers high flexibility in system design and minimises yield losses due to shading or uneven orientations.
• DC input voltage up to 1000 V: Enables long string designs, which reduces cabling costs.
• Active cooling (OptiCool): Ensures reliable operation and a long service life, even under high ambient temperatures.
• SMA Smart Connected: Automatic monitoring and communication of inverter faults.

Key Benefits

• Maximum Energy Efficiency: A high European Efficiency of 98.1% guarantees optimal energy yield from the installation.
• Flexible System Integration: The 12 MPP trackers provide excellent design freedom for installations on complex roof structures or with varying orientations.
• Lower Operational Costs (OPEX): The high power density and the possibility of long strings reduce installation and cabling costs per kilowatt peak.
• Advanced Monitoring: Integrated functionalities for string fault detection and monitoring via SMA's Smart Connected service minimise downtime.
• Durability and Reliability: OptiCool technology and a robust IP65 enclosure ensure long-term and reliable operation in diverse weather conditions.

Applications

This string inverter is extremely well-suited for large-scale commercial PV projects, such as large corporate building roofs, distribution centres, and ground-mounted solar installations in the utility sector. The high power class and flexible MPP tracking make this product ideal for complex projects where maximum yield and reliability are crucial.

Warranty and Durability

The SMA Sunny Tripower 125 comes with a standard manufacturer's warranty of 5 years. The inverter features an IP65 protection class, which guarantees complete protection against dust and water jets. The safe operating temperature range is between -25 °C and +60 °C, underscoring its operational reliability under heavy-duty conditions.
