100A MPPT Solar Charge Controller | Intelligent Solar Panel Regulator with LCD Display and Dual USB

This 100A MPPT solar charge controller maximizes the energy your solar panels produce. It uses advanced Maximum Power Point Tracking technology to deliver more power to your battery bank than standard PWM controllers, especially in cloudy or low-light conditions.

The built-in LCD display gives you clear, real-time information about system voltage, charging current, and battery status. Dual USB ports let you charge phones, tablets, and other small devices directly from your solar setup, making it a practical choice for off-grid cabins, RVs, or backup power systems.

Designed for 12V or 24V battery systems with an operating voltage of ≤36V, this controller is built with a durable PVC housing. It supports room electrical or hard wiring installation, giving you flexibility for permanent or temporary solar projects.

Key Features and Benefits

- MPPT technology that extracts more power from your solar panels compared to standard controllers, improving charging efficiency in variable sunlight

• LCD display that shows system data at a glance, so you can monitor performance without extra equipment

• Dual USB ports that let you charge phones and USB-powered devices directly from your solar system, adding convenience to off-grid living

• 100A rating that supports larger solar arrays and higher charging currents, suitable for medium to large battery banks

• PVC housing that provides basic protection for internal components, supporting reliable operation in indoor or sheltered installations

Who Is This For

- Off-grid homeowners who need a reliable solar charge controller to manage their battery bank and daily power usage

• RV and van lifers who want to maximize solar panel output and have USB charging available without an inverter

• DIY solar enthusiasts building a 12V or 24V system who need an MPPT controller with clear monitoring and easy setup

Usage Scenario

After installing solar panels on his cabin roof, Mark needed a controller that could handle variable weather. On overcast days, his old PWM controller barely charged the batteries. Switching to this MPPT controller, he saw a noticeable improvement in charging even when clouds rolled in. The LCD display let him see exactly how much power was coming in, and the USB ports meant he could charge his phone without running the generator.

Micro Comparison

Basic PWM controllers simply connect the panel to the battery, wasting any voltage above the battery level. This MPPT controller actively adjusts to find the panel's maximum power point, pulling more current from the same panel. The result is better performance in low light and cooler mornings, making it a smarter choice for anyone who wants to get the most out of their solar investment.

Questions and Answers

Question: Can this controller handle a 1000W solar panel array?

Answer: This 100A MPPT controller can handle up to about 1200W on a 12V system or 2400W on a 24V system, depending on your panel voltage and battery bank size.

Question: Does this work with lithium batteries?

Answer: This controller works with most 12V and 24V battery types, including lead-acid, AGM, gel, and lithium, but you should check the user manual for the specific charging profile settings.

Question: What size solar panel can I use with this controller?

Answer: The controller accepts an operating voltage up to 36V, so a typical 12V or 24V solar panel or a series string of panels within that voltage range will work.

Question: How do I set up the LCD display?

Answer: The LCD display shows system information automatically after connecting the battery and solar panel. Some models have buttons to scroll through different data screens like voltage, current, and battery status.

Question: Is this controller waterproof?

Answer: This controller is designed for indoor or sheltered use only. It is not waterproof and should be kept dry to prevent damage.
