FLOAT CONTROLLER CI

Module protection to fight PID-effect and TCO-corrosion

Float Controller CI is designed for larger photovoltaic Power plants with system voltages from 1000V to 1500V and therefore it is the perfect solution for central or string inverters.

Operation mode: Day or night mode / Adjustable tresholds

 

  • Fast recovery of PID affected modules due large output current
  • Immediate PID/TCO protection
  • Easy installation/retrofitting
  • Suitable for PV systems up to 1500V
