Renogy 12V 50A DC to DC On-Board Battery Charger w/ MPPT - Battery Charger

12V 50A DC-DC Dual Battery Charger

Renogy's enhanced DC-DC dual-input battery charger supports up to 50V solar input for faster, more efficient charging of compatible house-battery systems.

Intelligent Charging Mode Switching

Advanced charging logic and Low Solar Cutoff Mode support optimized charging performance as solar conditions change.

Versatile DIY Options

Connect compatible solar modules in series within the stated input limit to expand solar-array planning options for a DIY mobile-power system.

Adapt to Extreme Temperatures

Precise battery temperature compensation supports consistent charging efficiency in demanding temperature conditions.

NEG-Terminal Design for Easy Installation

The all-in-one negative-terminal layout consolidates connections for the solar array, starter battery and house battery to simplify compatible installation planning.

Comprehensive System Protections

Intelligent system safeguards are designed to protect compatible batteries, solar panels and alternators during charging operation.

Soft Start Circuit Design for Enhanced Battery Stability

The soft-start circuit gradually raises charger input voltage to reduce sudden electrical stress during startup.

Protect Your Solar Panels at Night

Reverse-current protection helps prevent current from flowing back from the battery to connected solar panels when solar input is unavailable.
