POWLSOJX 100A/80A/60A MPPT (Smart PWM) Solar Charge Controller 12V/24V/36V/48V Auto Battery Regulator with LCD Display Dual USB & Timer for Lithium/Lead-Acid

​

Product Description 

POWLSOJX Upgraded Solar Charge Controller – Your Reliable Power ManagerDesigned for off-grid solar systems, this upgraded controller features a premium aluminum alloy heat sink for superior cooling in hot climates and a smart chip for efficient power management. Whether you are powering a home system or a street light project, this controller automatically adapts to 12V, 24V, 36V, or 48V systems.

​

???? Why Choose This Upgraded Model?

​

Efficient Heat Dissipation: Unlike cheap plastic controllers, our upgraded model uses an aluminum alloy backplane. This ensures the controller stays cool and runs stably, even in high-temperature environments.

Intelligent Auto-Recognition: Automatically identifies 12V/24V/36V/48V system voltages. One controller covers all your needs, making system upgrades easy.

Multiple Battery Compatibility: perfectly compatible with Lead-acid (Seal, Gel, Flooded) and Lithium (LiFePO4) batteries.

Focusing MPPT Technology: Detects the maximum charging current. Efficiency is 10%-30% higher than ordinary PWM controllers.

Full Protection: Built-in 8 protection functions including reverse connection, over-current, over-temperature, and short-circuit protection to keep your battery and equipment safe.

​

⚠️ CRITICAL USER GUIDE (Please Read Before Buying)

To avoid damage to the controller, you MUST follow these voltage matching rules. This controller DOES NOT step down voltage (Not a Buck Converter).

1. Strict Voltage Matching Rule: ​The solar panel voltage must match your battery voltage. Do not use a high-voltage panel to charge a low-voltage battery.

​

For 12V Battery: You MUST use 15V-23V Solar Panels.

For 24V Battery: You MUST use 30V-46V Solar Panels.

For 36V Battery: You MUST use 45V-66V Solar Panels.

For 48V Battery: You MUST use 60V-90V Solar Panels.

2. Correct Installation Sequence: ​Always follow this order to allow the controller to recognize the voltage:

​

FIRST: Connect the Battery. (Screen will turn on).

SECOND: Connect the Solar Panel.

THIRD: Connect the DC Load (optional).(Reverse this order when uninstalling)

???? Product Manager's Tip for Troubleshooting:

​

Screen not lighting up? Check if your battery has enough voltage to start the controller (12V battery needs >10V).

Not charging? Check if your solar panel connection is loose or reversed, and ensure it's sunny.

Load icon flashing? You might have a short circuit or overload. Remove the short circuit, and it will recover automatically.
