Renogy DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT

  • Monitoring with Renogy ONE Core:   Add Renogy ONE Core to achieve smart energy monitoring with intuitive visuals and real-time data. It is an upgraded streamlined energy with our 3-in-1 smart panel.
  • Multi-Input Efficiency Charging:   The Renogy DC-DC Battery Charger with unique dual charging options. This multi-stage, multi-input battery charger can charge the house battery from a starter battery linked to the car alternator or by utilizing solar panels connected directly to the unit. Both ways can be charged at the same time to minimize charging time. With up to 99% MPPT tracking efficiency and 94% convert efficiency, the charger can fully charge a 1kWh battery within 2 hrs with solar energy.
  • Ingenious Structure Design:   Removable side covers avoid contact between product terminals and the human body during transportation and daily use, which results in electrostatic damage, ensuring product stability and safety. The all-in-one NEG- terminal with partition design integrates the terminals for solar panels, the array starter battery, and the house battery, avoiding misconnection and making the simple installation.
  • Diversified Smart Monitoring:   The Renogy 50A DC-DC Battery Charger uses the Modbus protocol and allows it to be compatible with various monitoring devices, including the RMS-DCDC monitoring screen, DC Home App, and Renogy One integrated screen. Managing and monitoring your energy easily and remotely in any scenario and situation.
  • Soft Start Circuit Design:   The voltage at the input end of the Renogy 50A DC-DC battery charger will be rising gently, intending to avoid when the vehicle alternator starts, the instantaneous overvoltage which may cause damage to the battery charger or cause the starter battery to over-discharge and due to the vehicle can not start.
  • Comprehensive Security Assurance:   The Renogy DC-DC Battery Charger is multi-certified to CE, FCC, and PoHs. This high-quality battery charger has multiple intelligent protections including battery isolation, over-voltage protection, battery temperature protection, over-current protection, overheat protection, reverse current protection, solar panel and alternator reverse polarity protection, guaranteeing charging safety and protecting your batteries.

Renogy's DC to DC MPPT on-board Battery Charger is designed to give you options! This multi-stage, multi-input battery charger can charge a service battery from a starting battery linked to an alternator or by utilizing solar panels connected directly to the unit. 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! And 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. With RJ45 communication port featured, you can unlock monitoring features exclusively using the BT-2 Bluetooth Module and Renogy DC Home App, control and monitor the device remotely through your phone in real time.
