TOPBULL 40 Amp MPPT Solar Charge Controller

TOPBULL 40A Smart Solar Charge Controller becomes the smart core of your solar power system with its excellent efficiency conversion, comprehensive safety protection, smart operation experience and excellent compatibility, injecting unlimited possibilities for your green life.

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%, ensuring that the system operates at its highest efficiency under all lighting conditions. Even under no-load conditions, its energy consumption is extremely low (less than 0.4W), effectively reducing energy waste.

The 40A MPPT Solar Charge Controller features highly efficient heat dissipation with specially designed metal heat sinks that allow heat to flow away quickly through the heat sink channels and dual high-speed smart fans to ensure rapid heat dissipation to maintain maximum charging efficiency. At the same time, the product is rugged, corrosion-resistant and of high quality, providing users with a stable and reliable charging experience.

Designed for efficient battery maintenance, this 40A solar charge controller supports a wide range of 12/24V battery types, including GEL, FLD, AGM, LI (Lithium Ion), and SLA. advanced MPPT technology ensures high efficiency charging at 40A, and built-in Li-ion charging and activation function effectively solves the problem of overcharging batteries.

TOPBULL 40A solar charge controller integrates a comprehensive 9-pronged safety protection mechanism, which can monitor voltage, current and load changes in real time to ensure the safety and stability of the charging process. At the same time, it also supports instantaneous high-current startup of large-capacity loads to meet the power needs of various devices. The quality of this controller is reliable and has passed many international certifications such as CE, FC, RoHS, etc., making it a trustworthy charging partner for users.

This 40A solar controller is easy to connect and install, which can effectively regulate the current of solar panels, ensure the safe and efficient charging of batteries, and improve the efficiency of energy conversion.

The MPPT 40A solar charge controller stands out for its high performance and intelligent design, which can increase power by up to 30% compared to PWM controllers. Its temperature compensation technology can automatically adjust the charging and discharging parameters at low temperatures, effectively extending battery life.

This solar charger has three working modes: normal mode for stable power supply, light control mode for automatically switching the load on and off according to the sunlight, and no-load protection mode to protect the system and cut off power to save energy. Users can switch easily and the settings are automatically memorized.

Solar charge controllers are crucial in off-grid solar power systems, regulating and managing the power generated by the panels, storing it safely and efficiently in the batteries, and stabilizing the power supply. Therefore, solar charge controllers are widely used in off-grid scenarios such as RV traveling, trailer traveling and outdoor camping.

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