12v Renogy 30A DC/DC Onboard Charger with MPPT Solar Control – DCC30S

Designed to give you options, the Renogy 30A Dual-Input DC-to-DC MPPT On-Board Battery Charger can charge a service battery in two different ways. The multi-stage charger can utilize connected solar panels or an alternator linked to a starting battery. While your vehicle’s alternator prioritizes your starting battery, this unit will allow your solar system to charge your service battery first! It’s the smart way to keep yourself fully charged and off-grid longer! With multi-stage charging and multi-chemistry functionality, Renogy’s DC-to-DC MPPT Charger has you covered whether you’re using Flooded, Gel, AGM, or Lithium batteries. Now you can unlock monitoring and control features exclusively using the BT-2 Module and Renogy DC Home App (available in both the App Store and Google Play).

  • ● Designed to charge service batteries from two DC inputs—solar panels and alternator .
  • ● Built-in Maximum Power Point Tracking (MPPT) to maximize the solar power.
  • ● 3-phase charging profile (Bulk, Boost, and Float) ensures your service battery will be accurately charged at the correct voltage levels to 100%.
  • ● Built-in Voltage Sensitive Relay (VSR) for easy setup with traditional alternators.
  • ● Compatible with smart alternators (with variable output voltage).
  • ● Trickle charges the starting battery via solar panels if the service battery is fully charged.
  • ● Isolation of the starting battery and the service battery.
  • ● Temperature and voltage compensation features prolong battery life and improve system performance.
  • ● Smart Protection Features: battery isolation, over-voltage protection, battery temperature protection, over-current protection, overheat protection, reverse current protection, solar panel and alternator reverse polarity protection.
  • ● Compatible with multiple battery types: AGM, GEL, Flooded, and Lithium.
  • ● Compact with a sturdy design, it was built tough for all conditions.
  • ● Bluetooth Monitoring Ready! Exclusively available with the BT-2 Bluetooth Module accessory and Renogy DC Home App available on the IOS and Google Play Stores.
