01PORTABLE SOLAR PANELS

Precise Solar Power Management

This compact regulator sits between your solar panel and battery bank, quietly managing the flow of energy. Its display offers a clear view of system status, allowing you to monitor performance at a glance.

Designed for lead-acid batteries including OPEN, AGM, and GEL types, it suits home, industrial, or commercial setups. The unit handles charging currents up to 40A, ensuring efficient power transfer without manual intervention.

40A 12V / 24V Solar Charge Controller PWM Intelligent Regulator With USB 5V 2.5A

DESIGN

Compact ABS Housing with Clear Display

Housed in durable ABS plastic, the controller measures 133 by 70 by 35 mm and weighs just 134 grams. Available in blue and black or orange and black, its small footprint allows for flexible mounting near the battery or panel. The integrated display clearly indicates status and data, making parameter configuration straightforward.

FUNCTION

PWM Regulation for Lead-Acid Systems

Using Pulse Width Modulation, the device improves charging efficiency specifically for lead-acid batteries such as OPEN, AGM, and GEL types. It automatically adapts to either 12V or 24V systems, handling maximum power inputs of 120W or 240W respectively. The adjustable floating charge voltage defaults to 13.7V, while discharge stop and reconnect voltages can be tailored to specific needs.

DETAILS

Dual USB Ports and Protection Features

Two USB ports offer a combined 5V 2.5A output, convenient for charging phones or tablets directly from the system. Built-in protections include safeguards for short-circuits, open circuits, reverse polarity, and overloads. With a self-consume current under 10mA, the unit remains efficient even when idle, operating reliably across temperatures from -35 to +60 degrees Celsius.

About this product

1, The solar charge controller equipped with dual USB ports, support 5V/2.5A max USB output. 2, This product provides short-circuit conservation,open-circuit conservation, reverse conservation, overload conservation. 3, Perfect and safe to use in various applications, such as home, industrial, commercial etc. 4, Solar controller can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration. 5, This product is perect for l-ead-acid batteries: OPEN, AGM, GEL, not suitable for nickel hydride, lithium ions, or other batteries. 6, Using PWM charge management, actually improve the c-harging efficiency. 7, Adjustable floating charge voltage, d-ischarge stop voltage and discharge reconnect voltage.

Make sure your battery has enough voltage for the controllers to recognize the battery type before installation.

The battery cable should be as short as possible to minimize loss.

The regulator is ONLY suitable for lead acid batteries: OPEN, AGM, GEL. (NOT suitable for nickel metal hydride, lithium ions or other batteries)

This controller can ONLY use photovoltaic panel as charging source, do NOT use DC or other power supply as charging source.
