All Charge Controllers
  • Outstanding system efficiency (max. 98%) thanks to integrated Maximum Power Point Tracker technology (MPPT)
  • Maximizes power output & reduces system costs
  • Encapsulated case provides full protection (IP68 protection class) increased lifespan
  • Intelligent timer and dimming functions for flexible lighting control
  • Auto-protect function: two voltage disconnects extend system operation time and increase reliability
  • Can be operated via CIS-CU IR remote control unit
  • Smallest size in its power class-fits everywhere
  • Data logger via MXI-IR and CISCOM Software
  • Compatible with 60-cell PV modules
  • With innovative maximum power point tracking technology, this Phocos MPP tracker ensures maximum performance and yield from all types of solar systems – year-round, in any weather, and in any environment.
  • The use of MPPT technology can contribute to a considerable boost in energy output from PV modules (up to 30% more). At the same time, the temperature-compensated, three-stage I-U curve charge control algorithm significantly extends battery lifespan.
  • The integrated data logger (2 years) provides an insight into system operation, displaying important information such as system status, voltage, current, etc.
  • PV panels primarily designed for grid connected systems (60 cell modules). The CIS-MPPT charge controller optimally charges 12V batteries with one (1) 60 cell module and 24V batteries with two (2) 60 cell modules wired in series.
