40A MPPT Solar Charge Controller 12V/24V
Product Overview
Topbull 40A MPPT: A New Choice for High-Efficiency Solar Charging
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.
Power Catcher MPPT Algorithm
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.
Highly Efficient Heat Dissipation, Long Lasting Efficiency
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.
Smart Recognition, Wide Compatibility
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.
Stable Charging, Worry-free Outdoor
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.
Innovative Three Working Modes
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.
Guaranteed Quality and Trustworthy
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.
Operating Instructions
You May Ask
How to choose the right 40A charge controller?
When choosing a charge controller, consider the total power of the solar panels, the type and number of batteries, and the projected load demand to ensure that all the components are compatible with each other.The Topbull 40A Solar Charge Controller is a great performer and worth having!
Can I connect multiple batteries to a 40A charge controller?
Yes, the 40A charge controller allows multiple batteries to be connected in parallel or series, but make sure that the batteries are of the same type, capacity, and follow a safe connection scheme.
Does this solar charge controller require frequent maintenance?
Our solar charge controllers are maintenance free, but it is recommended to regularly check the connecting wires, connectors and environment to ensure no corrosion or damage and to keep the system running properly.
Does using a charge controller affect battery life?
Proper use of a charge controller extends battery life, it prevents overcharging and overdischarging and keeps the battery in optimal condition.
Can a solar charge controller be used in conjunction with an inverter?
Yes, the charge controller can be used in conjunction with an inverter in order to convert DC power to AC power for use in the home or other devices. Go for a high quality inverter
Does the Topbull 40A charge controller make noise?
Our solar charge controllers do not make noise when working, but some high power MPPT controllers may be equipped with a fan to dissipate heat and may make a slight noise.
How effective are charge controllers in cold temperatures?
Low temperatures may affect the charging efficiency of the battery, and although the charge controller will operate, the performance of the battery may be degraded and should be used in a suitable environment.
Does the charge controller have an anti-reverse current function?
Topbull solar charge controllers are equipped with anti-reverse current function, which can effectively prevent the battery from charging in sunny days and then discharging at night.
Customer Reviews
I bought this charge controller (40A model) for my 800W back yard solar setup. It has worked well and keeps the batterrry bank topped up all the time. The readouts are simple and easy to understand. It pushes 30+ amps every day with no problems. When the fans come on they are very quiet. A good unit.
Arrived well packaged, with sturdy foam inserts to hold it in place in the box. The solar charge controller has a hefty metal heatsink on the back, twin cooling fans on the top and a large useful screen on the front. The USB ports are also handy on the bottom. Installation was easy, using the supplied template, such that the screw distances are exact when mounting on a wall.Operation is really good, with a solid output all the time, 32.7A shown on the attached picture. It's very handy to know, at a glance, the voltage and amperage amounts passing through. Am very pleased with the purchase and would recommend this 40A solar charge controller without hesitation!
Works great. Installed in my camper with a 320 panel and new lithium batteries. Charging great.
I used this solar charge controller to charge my 12 volt, 100 amp battery with 3 solar panels (my solar panels put out up to 400 watts, this controller can handle up to 480 watts at 12 volts). No issues. Good price, good quality, and quick delivery. I recommend this product.
Work better than last 2 that I bought much better charging to batteries. Which are Lithium
