Phocos CIS-N-20

PV solar charge controller


The CIS-N was especially developed to deliver optimum performance in industrial PV systems in demanding environments. It features 4-stage, series-switching PWM charge regulation and is fully programmable via infrared devices (CIS-CU or MXI-IR and CISCOM software). The CIS-N includes convenient and advanced lighting control, which allows the user to decide whether they want the automatic lighting control with LED dimming to be time or low-voltage activated.


  • Works in 12 or 24 V systems (auto recognition) 
  • Fully programmable charge/discharge program via infrared (CIS-CU or MXI-IR and CISCOM software) 
  • Timed and low-voltage dimming settings 
  • Dimming interface for external LED drivers 
  • Fully potted (IP68) aluminum housing 
  • UL1741/Class I Div. 2 certified 
  • Infrared-programmable load timing feature with dimming, ideal for lighting systems
