250kW 240V High-Leg Delta Industrial Hybrid Inverter

Megawatt-Scale Power Conversion Solution

1. Product Introduction

This industrial-grade 250kW hybrid inverter represents the pinnacle of three-phase power conversion technology, specifically engineered for heavy industrial applications and utility-scale microgrids.

*Technical Insight: Utilizes patented phase-shifting technology to generate true three-phase 240V (line-to-line) while simultaneously providing 120V (line-to-neutral) output, eliminating the need for external transformers.*

Key Features:

• 250kW continuous (275kVA peak) power output
  *Engineering Note: Achieved through three-level ANPC topology with 98.7% peak conversion efficiency at nominal load.*

• Six independent MPPT channels for maximum solar harvest
  Technical Advantage: Reduces mismatch losses by up to 40% in complex array configurations compared to conventional designs.

• 420-850V battery voltage range for modern storage systems
  *System Benefit: Direct integration with high-voltage lithium batteries reduces system complexity and improves round-trip efficiency by 2-3%.*
