All Charge Controllers
  • Battery state-of-charge indication via 3 LEDs
  • Load disconnect pre-warning via acoustic signal
  • Four-stage PWM charging algorithm with (integrated) temperature compensation (float, main, boost, and equalization charging)
  • Automatic 12/24 V detection
  • Large terminals: up to 16 mm2
  • SOC and voltage-controlled LVD
  • Full electronic protection
  • Aluminum housing (IP20)
  • Charger for external devices via USB port
  • Remote output connector for the Phocos inverter series
  • The CMLsolid charge controller is the next stage in the development of the CML series. The controller is equipped with a number of outstanding features such as an aluminum housing, USB port, battery status display, alarm, and electronic protection against reverse battery polarity and reverse solar polarity.
  • The temperature-compensated,four-stage PWM charging algorithm (float-main-boostequalization) is adjustable for sealed and vented lead-acid batteries. The CMLsolid also allows either a SOC or voltagecontrolled low-voltage disconnect.
  • Battery status is clearly indicated via three LEDs, with an alarm for signaling a low-voltage disconnect.
