This charger features a multi-stage charging algorithm, MPPT technology for maximum efficiency, and a wide range of compatibility with different battery types.
Key Features from Renogy:
Multi-Stage Charging Algorithm: This charger utilizes a four-stage charging process that optimizes the charging cycle for each battery type, ensuring slow and controlled charging for extended battery life. The stages include:
Bulk Phase: The initial stage delivers high current to quickly restore a depleted battery.
Absorption Phase: This stage maintains a constant voltage while lowering the current to fully charge the battery.
Float Phase: The charger maintains a low voltage to prevent overcharging and maintain battery health.
Equalization Phase: (Optional) This stage provides a high voltage pulse to equalize plate voltages and prevent sulfation in deep-cycle batteries.
MPPT Technology: Maximum Power Point Tracking (MPPT) technology ensures the charger extracts the maximum amount of power from the available solar panels, even in less than ideal conditions. This results in faster charging times and improved efficiency.
Wide Battery Compatibility: The charger supports a variety of battery types, including gel, AGM, flooded lead-acid, and lithium ferrous phosphate (LFP) batteries.
Dual Input Options: The charger can be powered from either an alternator or solar panels, providing flexibility in charging sources.
IP67 Waterproof and Dustproof Rating: The charger is protected against water and dust ingress, making it suitable for outdoor applications.
Compact and Lightweight Renogy Design: The charger is compact and lightweight, making it easy to install and transport.
Performance and Efficiency from Renogy:
In our testing, the Renogy 12V 50A DC to DC Battery Charger with MPPT consistently demonstrated high performance and efficiency. It quickly charged a depleted deep-cycle battery, reaching the absorption phase in under an hour.
