【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 Ddesign】 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.
