Unlock the True Potential of Your Solar Energy System

Hitachi Hi-Rel's Grid Tied Solar String Inverters HIVERTER-Si-N Series, is versatile and highly efficient solution ideal for rooftop solar power plant installations on commercial and industrial buildings. These inverters enable distributed power generation very close to the consumption point, effectively reducing electricity demand from the distribution network during peak daytime hours when solar production is highest. This leads to significant reductions in transmission demand and grid losses, making them a cornerstone for optimized and cost-effective solar energy utilization.

Models:
- HIVERTER-Si Series (1500 VDC): Designed for higher DC voltage systems.
- HIVERTER-Si-N Series (1000 VDC / 1100 VDC): Available in various power ranges for different system requirements.

Range:
- Single Phase (1000 VDC): 1.1 kW / 1.6 kW / 2.2 kW / 2.7 kW / 3 kW / 3.3 kW, 4kW, 5 kW & 6 kW
- Three Phase (1100 VDC): 4.4 kW / 5.5 kW / 6.6 kW / 8.8 kW / 11 kW / 12 kW, 20 kW / 25 kW / 30 kW / 33 kW, 50 kW / 60 kW / 80 kW / 110 kW / 125 kW
- Three Phase (1500 VDC): 350 kW, 250 kW / 255 kW (HIVERTER-Si Series)
