The latest from CTEK the D250SE leverages on the good foundation of the D250SA Dual but raises the stakes again by including a Lithium Charge profile to feature alongside its ignition feed and MPPT solar controller. A wider input voltage range on the alternator side for Euro 5+ engine for ECU controlled systems.

MPPT Solar input, alternator input with service battery charging from the solar or engine with a preference on the sun's free energy. Not to mention the ability to add the SmartPass 120S or SmartPass 120  for an additional 120A charging output.

  • 20A fully automatic temperature compensated charging for batteries from 40-300Ah while you’re on the move
  • Dual input (solar and alternator in parallel)
  • Smart alternator compatible
  • Selectable lithium* and lead-acid mode
  • Solar panel regulator with Maximum Power Point Tracking (MPPT)
  • Battery separation replacing diodes and VSR relays
  • Selectable AGM option – 14.4V or 14.7V
  • Maximised charging for better battery life and performance
  • Temperature sensor to compensate for hot or cold conditions
  • Compatible with SMARTPASS 120 for the ultimate 140A power management solution

    *Lithium Battery Bank must utilise it's own battery monitoring system which will work in conjuction with this devices output voltages.
