40A MPPT Solar Charge Controller 12V/24V

Topbull 40A MPPT solar controller utilizes industry-leading MPPT technology to intelligently track the maximum power point of the solar panels, allowing for efficient operation even when the light varies, providing more power than traditional PWM controllers, effectively charging the battery, extending its lifespan, and reducing reliance on traditional energy sources. It also features automatic voltage detection, compatibility with a variety of deep cycle batteries, comprehensive protection mechanisms, efficient heat dissipation and temperature compensation to ensure safe and stable operation of the system.

Topbull 40A MPPT solar charge controller, with its innovative Power Catcher MPPT algorithm, achieves a tracking efficiency of 99% and a high conversion efficiency of 98%, which ensures that the system operates at the highest efficiency under any lighting conditions. Even under no-load conditions, its energy consumption is extremely low (less than 0.4W), effectively reducing energy waste. Compared to traditional MPPT controllers, it captures up to 30% additional energy and outperforms other similar products by 10% in power utilization, providing superior performance and maximum power yield for your solar power system.

The 40A MPPT solar charge controller combines high heat dissipation with durability. The specially designed metal heat sink and dual high-speed smart fans ensure that the device maintains optimal efficiency when charging. At the same time, the application of high-strength corrosion-resistant materials makes this controller work stably in various environments.

This 40A MPPT solar charge controller has a wide range of battery compatibility, supports charging of a wide range of 12V/24V batteries, and is equipped with intelligent MPPT technology to efficiently track the maximum power output of the solar panel. Meanwhile, the device has a built-in temperature compensation function that automatically adjusts the charging parameters to adapt to different temperature environments, ensuring safe battery charging.

This 40A MPPT solar charge controller supports up to 100VDC photovoltaic input voltage and is suitable for both 12V and 24V solar systems, which can carry a maximum input power of 450W and 960W respectively. It is designed to be both rugged for outdoor use and portable, providing users with a stable and reliable solar charging solution.

This solar charge controller is innovatively designed with three modes: lighting control (can be set to switch on and off for 1-24 hours), all-weather automatic shutdown and intelligent mode that automatically adjusts according to the load status to adapt to different needs. It also supports lithium activation to enhance battery performance.

Topbull controllers have successfully passed a number of authoritative certificates including CE, FCC and ROHS to ensure the reliability and safety of the products due to their excellent quality.
