SG1100UD×3-MV/SG1100UD×4-MV
Saving investment
- “Integration” of “reversal” and “transformation,” rapid deployment, unified maintenance
- Reserved energy storage interfaces save on later retrofit costs
Flexible and convenient
- System modularization, flexible expansion of photovoltaic capacity ratio and energy storage capacity
- The device is modular and plug-and-play, requiring no professional maintenance
Safe and reliable
- Real-time DC parallel arc pulling monitoring, 40ms shutdown
- AC low-voltage full copper busbar connection, eliminating the risk of insulation failure
- Inverter + box transformer integrated factory testing for greater reliability
Supporting the power grid
- Reactive power response time < 20ms, better than national standards
- SCR=1.02, extremely weak network runs stably
- Optical storage DC coupling ensures smooth output
