QUESTIONS & ANSWERS

Ask a Question

  • Can this charger charge 2 batteries at the same time on a boat? 1 house battery 1 starting battery?

    Yes, the charger can charge both a starting battery and a house battery if the two batteries are connected through a battery isolator, Automatic Charging Relay (ACR), or a battery selector switch. In this setup, the solar charger will maintain both batteries.

    If the starting battery and house battery are completely separate and not connected by a battery management system, the charger can only charge one battery at a time.

  • Can you tell me the three stage charge voltages for the different battery chemistries for the 50 watt maintainer ultra?

    12V Mode:  Boost charge voltage 14.4V, Float charging voltage 13.8V

    12V AGM: Boost charge voltage 14.6V, Float charging voltage 13.8V

    12V Lithium: Boost charge voltage 14.6V, 

  • what are the dimensions of the panel?

    The dimension is 23.2x17.3x0.16Inch
