Efficiency Performance Overview

This document excerpt from Sungrow USA Corporation (2016) presents efficiency data related to normalized output power at different DC voltage levels.

Efficiency vs. Normalized Output Power

The efficiency curves are shown for three DC voltage inputs: 480V, 710V, and 850V. The efficiency ranges approximately between 90% and 98% across the normalized output power spectrum from 0% to 100%.

Key points include:

  • Efficiency improves as normalized output power increases.
  • At higher DC voltages (710V and 850V), efficiency tends to be slightly higher compared to 480V.
  • The maximum efficiency approaches around 98% near full output power.

Implications

This data suggests that operating at higher DC voltages can yield better efficiency performance in power conversion systems. The efficiency curves provide critical parameters for system design and optimization.
