The SRNE MD12100is a high-efficiency, multi-stage DC-DC charger and MPPT solar charge controller designed for dual-battery systems in vehicles, boats, and off-grid applications. It intelligently manages power from both solar panels and a vehicle alternator or generator, ensuring that the auxiliary battery is charged safely, efficiently, and reliably under all conditions. Key Features Dual Input Charging: Accepts power from both alternator and solar sources, charging the auxiliary battery independently from the starter battery. MPPT Solar Technology: Utilises advanced Maximum Power Point Tracking to extract the maximum possible power from solar panels, improving overall charging efficiency by up to 98%. Multiple Charging Modes: Supports solar charging only, alternator charging only, or simultaneous charging from both sources. Automatic Battery Detection: Compatible with standard and smart alternators, making it ideal for modern vehicles. Multi-Chemistry Support: Works with Sealed, Gel, Flooded, and Lithium (LiFePO₄) batteries, with user-customisable charging parameters. Comprehensive Protection: Built-in safeguards against overvoltage, overcurrent, overheating, reverse polarity, and night-time reverse charging. Compact & Efficient Design: Fanless cooling, ultra-low standby power consumption (<0.6 W), and durable IP32 enclosure for reliable performance.
