NOW HIRING: Production Electronics Technicians

35kVA Power Conversion System


With a compact, 3U form factor, the transformerless OZPCS-RS35 power conversion system installs directly into Li-ion battery racks. Front-side terminations simplify interconnect, and the fully parallelable, 35kW architecture permits easy system expansion. Optimized for 3-phase and split-phase grid connection and 400-800VDC battery voltage, and with grid-tie and grid-forming operating modes, advanced “Smart Inverter” features, and design and certification for energy storage applications, system design doesn’t get any easier.


  • Optimized for 120/208V 3-phase and 120/240V split-phase applications
  • Supports grid-tie and grid-forming applications
  • Easy paralleling allows for quick product scaling
  • NEMA 3X outdoor-rated wall-mount design
  • Wide AC voltage range
  • 50/60Hz
  • UL1741-SB smart inverter functions
  • 3- and 4-wire transformerless grid interface
  • Integrated data logging
  • Industry-standard interface
  • SunSpec certified
  • Modbus RS-485
