12V dual solar charge controller 14A escpecially for caravans and boats. Of course it's also suitable for other autarkic solar systems. Charges on-board and starter battery.

For solar modules with:
max. 220Wp module output
max. 14A module current
max. 28V module voltage

Features:

  • Main output (1): automatic charge and load preservation of the main supply battery (on-board battery)
  • Second output (2): current and voltage-reduced to recharge and preserve starter batteries and keep them operational
  • stepless regulation: full battery through instant recharge after consumption
  • Automatic charge program for Gel, acid/wet, AGM and lithium batteries
  • Very low consumption
  • Connectable to a battery temperature sensor
  • Displays: 'full', '>80%', 'charging', 'stand-by' and 'undervoltage'
  • Smooth battery charging - no overload 
  • maintenance-free

Through intelligent micro-processor controlling the batteries are charged optimally with IU1oU2 curves.
