Function Details

RVs, exposed cars, campers, ships Battery to battery DC & Solar Panel 10-16v 12v Input to 14.6V Boost DC to DC Charger 30A Lithium battery with 2 charging sources. You can use the battery (12V) to charge the battery (12V) (B2B), or you can use the solar panel to charge the battery with automatic intelligent switching charging methods, specially designed for RVs, exposed cars, campers, ships, etc.

B2B Operation:

Mobile operation from dynamo and starter battery (Battery to Battery):

Refers to charging the main battery through dynamo and starter battery. If not used in a vehicle, you can also use one 12V battery to charge another.

  • The efficient charging converter (booster) allows full charging of the board battery during driving.
  • It increases/reduces the voltage to the required level for precise charging of the board battery with the optimum charging characteristic curve.
  • Simultaneously supplied 12 V consumers are protected against overvoltage and voltage fluctuations.
Solar Operation:
  • The controller can improve the charging efficiency of the solar panel by 10-30% through MPP technology (automatically calculating the maximum power yield), effectively shortening charging time.
  • The controller can charge the main battery according to the specified current by boosting or stepping down to ensure that the main battery is charged according to the standard charging curve.
  • Auxiliary charging supports support charging and trickle charging of the vehicle's starter battery in case of extended standstill periods.
