15A 500W Boost MPPT Solar Charge Controller, Step-Up Voltage Regulator for 24V/36V/48V/60V/72V Lead-Acid, LiFePO4 & Lithium Batteries, Ideal for Golf Carts, eBikes, Solar Systems

• 【Advanced MPPT Boost Charging】Industry-Leading 97% Efficiency: Utilizing cutting-edge MPPT and Pure Boost Topology, our controller delivers peak 97% charging efficiency. It perfectly steps up solar voltage (13V-60V Input) to charge high-voltage batteries (24V-72V Output), maximizing every drop of energy for your Golf Carts or EVs.
• 【One-Key Voltage Setup & Wide Compatibility】Simplify your workflow with our One-Key Setting feature, allowing you to toggle between 24V to 72V systems instantly. The customizable constant voltage points ensure full compatibility with Lead-acid, Lithium, GEL, and Flooded batteries.
• 【Real-Time Data Monitoring】Stay fully informed with our multi-data LED display. Unlike basic models, our screen provides real-time tracking of Charging Current, Battery Voltage, and PV Input Voltage, complemented by LED status indicators for "at-a-glance" monitoring.
• 【Zero Standby Power Consumption】Engineered for sustainability, the system is powered directly by solar panels, significantly reducing battery drain. With 0W standby power consumption, your battery stays protected even during long periods of inactivity.
• 【Smart Silent Fan Cooling】Forget the loud, constant whirring of traditional controllers. Our unit features a built-in intelligent cooling fan designed for ultra-silent operation. It activates only when necessary, providing powerful active heat dissipation to maintain optimal performance while keeping noise to an absolute minimum.
• 【Comprehensive Safety Protection】Your safety is our priority. Built-in safeguards include Overcharge Protection (preventing battery damage), Reverse Polarity Protection, and advanced circuit defense to ensure a secure and reliable charging environment for your Electric Vehicles or Solar Kits.
