600W 30A Boost MPPT Solar Controller, Step-Up Charging from 17V-55V Panels to 24V-85V Battery Banks-99% Tracking Efficiency, 30A, Pure Copper Inductor, Compatible with Lead-Acid/Lithium/Gel

• BREAK THE VOLTAGE LIMIT (TRUE BOOST TECHNOLOGY): Unlike standard buck controllers, our advanced Boost MPPT technology allows you to charge high-voltage battery packs (24V, 36V, 48V, 60V, 72V) using low-voltage solar panels (17V-55V). This is the perfect solution for Golf Carts and E-Bikes with limited roof space—use a single standard 18V panel to efficiently charge your 48V or 72V system without complex series wiring. Note: Solar input voltage MUST be lower than battery voltage.
• 0V BATTERY RESCUE FUNCTION: Don't throw away your "dead" lithium batteries. The CPL series features a specialized wake-up function that activates BMS-protected lithium batteries (reading 0V) that have been over-discharged. It delivers a 30% more efficient activation pulse to restore your battery's charging capability, saving you the cost of premature battery replacement.
• PRO-GRADE THERMAL DESIGN (INDOOR VERSION): Engineered with a heavy-duty aluminum alloy chassis and an Open-Air Passive Cooling architecture, this controller maximizes heat dissipation during high-current boost conversion. Important: This model is designed for DRY LOCATIONS ONLY (e.g., inside dashboards, cabins, or battery boxes). It is NOT waterproof; strictly avoid exposure to rain or moisture to ensure longevity.
• WIDE COMPATIBILITY & CUSTOMIZATION: One controller for all your projects. Preset supports Lead-Acid, Gel, Liquid, and Lithium batteries across 24V-72V systems. For advanced users, the "User-Defined" mode allows fine-tuning of the charging cutoff voltage (24V-85V range) via a simple digital interface, ensuring your specific battery chemistry gets the exact charge it needs.
• INDUSTRIAL BUILD & PROTECTION: Built with a pure copper boost coil for reduced resistance and higher conversion efficiency (up to 98%). The system offers comprehensive 6-stage electronic protection against over-temperature, reverse connection, short circuits, and over-current. The real-time LED display allows you to monitor PV voltage, battery voltage, and charging power at a glance.

Why Choose POWLSOJX CPL Boost MPPT Controller?

Are you struggling to charge your 48V, 60V, or 72V e-bike or golf cart because standard solar panels only output 18V or 36V?

The POWLSOJX CPL Series is the solution. Unlike standard "Buck" controllers that require solar voltage > battery voltage, our Advanced Boost Technology allows you to charge high-voltage battery banks using low-voltage flexible or rigid panels.

True MPPT Boost Technology (Step-Up Charging)Break the physical limits! Efficiently charge 24V, 36V, 48V, 60V, or 72V battery systems using just a single 18V (17V-55V) solar panel.

Example: Use one 18V/100W panel to charge your 48V E-scooter directly!

0V Battery Activation (Dead Battery Rescue)Don't throw away your "dead" lithium battery! If your battery management system (BMS) has locked due to low voltage, the CPL controller can wake it up. Our activation efficiency is 30% higher than standard market models.

Universal Battery CompatibilityOne device for all types. Perfectly compatible with:

Lithium-ion / LiFePO4 (Customizable voltage)

Lead-Acid / Gel / AGM

User-Defined Mode: Adjust charging voltage from 24V to 85V.

Industrial Grade Build & 99% EfficiencyBuilt with a Pure Copper Inductor and high-quality capacitors to minimize heat and maximize conversion. The advanced MPPT algorithm tracks power points with ≥99% efficiency, ensuring you get every watt of power from the sun.

Pro-Cooling Aluminum Design (Indoor/Cabin Version)Features a rugged aluminum alloy shell designed for maximum thermal convection.

IMPORTANT INSTALLATION NOTES (Read Before Buying)

1. Voltage Rule: The Solar (PV) Input Voltage must be LOWER than the Battery Voltage for the boost function to work. Correct: 18V Panel -> 48V Battery. Incorrect: 36V Panel -> 12V Battery (This controller cannot step down).
2. Environment: This model utilizes an open-air cooling architecture for better performance. It is NOT waterproof. Please install it in a dry location, such as inside your vehicle dashboard, under the seat, or in a battery box.
3. Setting Mode: To adjust voltage, long-press the SET button for 5 seconds until the display flashes, then use the +/- keys to set your target voltage.

Parameterzs

Perfect Application Scenarios

1. E-Mobility: Golf Carts, Electric Tricycles, E-Scooters, Electric Wheelchairs (Install under the seat/dashboard).
2. RV & Marine: Boosting portable solar panel voltage for 48V system upgrades.
3. Home Energy Storage: Charging 48V server rack batteries with smaller, repurposed solar panels.
