60kW / 120kW Automatic Switching Gear
NESTS-(60~120)KR STS
Compatbile with SINY 30kW & 70kW battery inverters or hybrid inverters

Automatic on-/off-grid monitoring and switching unit
60kW / 120kW Automatic Switching Gear
  • 2U Modular design. Higher power density, with 60kW in 2U compact size,120kW in 4U size.
  • Excellent compatibility. The STS is compatible with both SINY NESI series battery inverter and solar battery hybrid inverters
  • < 20ms quick switching. Within 20ms fast switching between on-grid and off-grid status, uninterrupted protection on important loads like servers possible
  • Automatic monitoring and switching. Communicating with EMS and battery inverter(PCS), the STS can be automatic switching when power outages.
