With its advanced charging logic, this DC to DC charger prioritizes solar power when available. If solar power is insufficient, it uses both solar and generator power. When solar power is very low, it relies solely on the generator (starter battery) while keeping the starter battery within a safe voltage range. It provides a max of 30A total output regardless of the charging method.\n- 12V-24V Buck Boost Battery Charger: Featuring buck and boost charging logic, this on board battery charger supports both 12V and 24V systems. It can boost 12V power to charge a 24V battery and buck 24V power to charge a 12V battery. This allows your auxiliary battery to charge your starter battery, and vice versa, if your battery systems have different voltages. Note that the buck and boost functions do not apply to solar array systems.\n- High-Efficiency MPPT Solar Charge Controller: This DC to DC charger with MPPT uses advanced technology to achieve up to 99% tracking efficiency and 98% peak conversion efficiency, about 30% higher than PWM controllers. It features smart 3-phase charging stages (Bulk, Boost, Float) to regulate the entire charging process, ensuring batteries are accurately charged to 100% at the correct voltage levels. It supports LiFePO4, sealed, AGM, GEL, flooded, and user-customized battery types.\n- Smart Bluetooth App Control \u0026amp; Monitoring: Equipped with a built-in Bluetooth module, this 12V\/24V DC to DC battery charger works with the \"ChargePro 2.0\" app for real-time monitoring and stores up to 300 days of historical data. You can also set battery parameters easily via the app. Note: Bluetooth connection is effective within a 10m\/33ft range (in an unobstructed area).\n- All-Round Safety Protection \u0026amp; High-Temp Resistant Materials: This DC battery charger offers all-around safety with multiple protections, including PV over-voltage, PV reverse polarity, battery over-voltage, overcharge, battery reverse polarity, EXT input over-voltage, EXT reverse polarity, overheating, and high ambient temperature safeguards. The connection terminals are made from high-temp resistant materials, ensuring safety even under high current conditions.\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003eSilent Heat Dissipation\u003c\/p\u003e\u003cp\u003eStarter Battery Protection\u003c\/p\u003e\u003cp\u003eUse Provided Terminals\u003c\/p\u003e\u003cp\u003eMulti-Alternator Compatibility\u003c\/p\u003e\u003cp\u003eCan I use this charge controller with solar panels and a generator simultaneously?\u003c\/p\u003e\u003cp\u003eCan this charge controller charge different voltage systems?\u003c\/p\u003e\u003cp\u003eIs there protection for my starter battery when it charges the auxiliary battery?\u003c\/p\u003e\u003cp\u003eIs there any heat dissipation design?\u003c\/p\u003e\u003cp\u003eHow does the MPPT feature benefit my charging system?\u003c\/p\u003e\u003cp\u003eOur DC to DC charger is equipped with an integrated heat sink on the back, ensuring efficient heat dissipation and optimal charging performance.\u003c\/p\u003e\u003cp\u003eOur on-board charger features smart detection protection, ensuring your starter battery always has enough power for your vehicle.\u003c\/p\u003e\u003cp\u003eOur terminal connection part features high-temp resistant materials that won’t deform under high currents, reducing the risk of damage.\u003c\/p\u003e\u003cp\u003eCompatible with traditional and smart alternators, this DC-DC charger features an IGN port for auto-activation with smart alternators.\u003c\/p\u003e\u003cp\u003eCan I use this charge controller with solar panels and a generator simultaneously?\u003c\/p\u003e\u003cp\u003eYes, it supports dual input from both solar panels and generators.
