Overview
The POWLSOJX CPL series MPPT boost solar charge controller is designed to charge higher-voltage battery systems from lower-voltage PV panels using step-up (boost) charging. It supports 24V/36V/48V/60V/72V battery systems and is intended for applications such as golf carts, e-bikes, e-scooters, and other off-grid charging setups where PV voltage is lower than battery voltage.
Key Features
- MPPT boost (step-up) charging: PV input 17V-55V, intended for charging higher-voltage batteries (PV voltage must be lower than battery voltage).
- Adjustable battery/charge voltage: user-defined mode supports 24V-85V (adjustable).
- 0V battery activation: battery wake-up function; activation efficiency stated as 30% higher / 30% more efficient activation of 0 V Li-ion battery.
- Battery compatibility (as stated): lithium-ion / LiFePO4 (customizable voltage), lead-acid / gel / AGM, and “common battery”.
- MPPT tracking efficiency: ≥ 99%.
- Cooling/installation: aluminum alloy housing with open-air cooling architecture; non-waterproof design for dry, ventilated installation.
- Real-time dual display (as described in product materials).
- Protection functions (as stated): over-temperature, short circuit, PV over-voltage (also described as PV overpressure), overcurrent, reverse connection protection.
- Internal build highlights (as described): pure copper boost coil and high-quality circuit components.

Applications
- E-mobility charging: golf carts, electric tricycles, e-scooters, electric wheelchairs.
- Caravan & marine (LiFePO4 battery system).
- Home energy storage: charging 48V batteries using smaller/repurposed solar panels.
- Agricultural irrigation (high pressure water pump).
- Off-grid power supply (lighting, monitoring).
Important Installation Notes
- Voltage rule (boost only): PV input voltage must be lower than battery voltage for boost charging to work.
- Example stated: 18V panel → 48V battery (works). 36V panel → 12V battery (does not work; not a step-down controller).
- Non-waterproof: install in a dry, ventilated area (open-air cooling design). Avoid rain exposure.
- Setting mode: long-press the SET button for 5 seconds until the display flashes, then use the +/- keys to set the target voltage.

Details
Use a lower-voltage PV panel to charge higher-voltage battery systems for e-mobility, RV/marine LiFePO4 setups, irrigation, and off-grid loads.
Boost MPPT charging helps when panel voltage is lower than the battery pack, such as 17–55V solar input charging 24–72V systems.
A pure copper boost coil and quality components support stable step-up charging and MPPT performance.
Supports 24V/36V/48V/60V/72V battery systems with step-up charging from 17–55V photovoltaic input.
Built-in electronic protections include over-temperature, short circuit, PV over-voltage, overcurrent, and reverse connection safeguards.
