The SOLAR WARE 1833GRQ/Solar Ware 1667ER(J) is one of the largest central PV inverter in the 1000V power class. The first heat-pipe based hybrid cooling technology implemented in utility-scale PV inverter solution providing optimal opex model.

New technology innovation

  • Proprietary 3-level (Advanced Multi-level) IGBT architecture provides reduction on switching loss and performance enhancement through filter reactor size optimization
  • Industry's leading 98.6% efficiency (including auxiliary power consumption)
Heatpipe Technology

World's first heatpipe technology in utility-scale PV inverter

  • Utilizing TMEIC heat pipe technology, the inverter runs without fan operation up to 40% load
  • Heatpipe cooling significantly simplifies thermal management, because it uses fewer parts and only a slow-speed fan with a heat pipe heat sink

Easy System Integration

  • Full direct bus connection both on DC and AC side provides easy installation on-site
