Product details

The Kostal Solar Electric inverter is a highly advanced, transformerless voltage converter known for its versatility. It can be universally used as a solar, hybrid, or battery inverter and offers a base AC power output of 4.0 kW, which can optionally be expanded to 5.5 kW or 7.0 kW. With three MPP trackers, each supporting a maximum MPPT current of 17 A, this inverter enables efficient energy generation and utilization. The integration of a device with a display, data logger, and system monitoring ensures user-friendly handling and control. Additionally, the inverter is prepared for the subsequent activation of a third MPP tracker, allowing connection to compatible high-voltage storage systems. The capability for backup power operation, both manually and automatically, along with support for fast shading management and digital outputs for load control, makes it a flexible solution for various applications.

  • Three MPP trackers for optimized energy generation
  • Preparation for additional battery charging via AC energy sources
  • Integrated system monitoring and control interfaces
  • Backup power operation with manual and automatic switching
  • Free monitoring via KOSTAL Solar Portal and Solar App.
