The BlueSolar PWM DUO 12V|24V|20A LCD-USB series uses Pulse Width Modulation (PWM) charge voltage control combined with a multistage charge control algorithm. This leads to superior charging and enhanced battery performance. The filtered PWM power control system uses highly efficient and reliable power MOSFET transistors.

Features

• Liquid crystal display. For status monitoring and set-up
• External Temperature sensor included
• 2 Separate Battery outputs. Charges two separate batteries. For example, the starter battery and the service battery of a boat or mobile home.
• Protections. Protected against reverse polarity connection of the solar panels and/or battery
• Programmable battery charge algorithm. Algorithms for AGM, GEL or Flooded lead-acid batteries and LiFePO4 batteries (with internal BMS).
• Two 5 Volt USB outputs. Maximum current of the two outputs combined: 2A
