Sungrow SG150CX Multi-MPPT String Inverter for 1000 Vdc System

The Sungrow SG150CX is an advanced Multi-MPPT string inverter, specifically designed to deliver maximum yield in large-scale commercial and industrial (C&I) PV installations with a 1000 Vdc system architecture. This transformerless model combines high efficiency with robust protection and intelligent management for reliable operation.

Key Features

• Multi-MPPT and High Yield: Features 7 independent MPPT inputs (3 strings per MPPT) for optimal energy production in complex configurations. The system is optimised for a maximum efficiency of 98.8% and includes a Global MPPT scanning function that increases yield by more than 2%.
• Higher Current Input: Suitable for a higher current input, making the inverter compatible with all PV modules and offering more design flexibility.
• Integrated Protection: Equipped with an Intelligent DC Arc Interrupter (AFCI 3.0) with a detection range of 450 metres, a DC switch, and surge protection (DC Type I+II/AC Type II).

Main Benefits

• Maximum Energy Efficiency: The high maximum efficiency of 98.8% (98.2% European efficiency) and Global MPPT scanning ensure an optimised energy yield.
• Exceptional Durability: Features IP66 protection and C5 Anti-corrosion protection, guaranteeing reliable operation in diverse harsh environmental conditions.
• Smart Operation and Maintenance (O&M): Functions such as Air Duct Self-Cleaning reduce maintenance requirements and increase O&M efficiency.
• Advanced Diagnostics: Offers High-Precision String Detection and I-V diagnosis to accurately locate abnormal strings, enabling rapid fault resolution.
• PID Recovery: The built-in Intelligent PID recovery function contributes to the long-term performance of the modules.
• Flexible Communication: Standard equipped with RS485 and options for WLAN or Ethernet for comprehensive monitoring.

Applications

The SG150CX is primarily suitable for large-scale commercial rooftop projects, industrial installations, and utility-scale solar energy projects that require a robust and efficient solution. The IP66 and C5 rating makes the inverter ideal for outdoor installations in maritime or polluted industrial environments.

Warranty and Durability

The inverter is designed for a long service life and minimal downtime, supported by the IP66 degree of protection and the C5 corrosion protection. The operational temperature range runs from -30 °C to + 60 °C. The integrated PID recovery function helps counteract the performance degradation of the connected PV modules.
