20A MPPT Solar Charge Controller W/ Circuit Breaker

Add solar to your home or RV with this MPPT solar charge controller and circuit breaker. This 20A MPPT Solar Charge Controller was only installed on my trailer for about six months. I recently increased the number of solar panels and had to go to a higher amperage charge controller. This controller can handle up to 240 W of solar panels and includes the necessary 30 amp circuit breaker. All items are in like new condition and include the original manuals. Here are additional details on the controller: 99% Tracking Efficiency - this 20A MPPT has advanced maximum power point tracking technology. It continuously tracks the maximum power point of the array to obtain maximum power to charge the battery. The tracking efficiency is no less than 99% and the peak conversion efficiency is up to 98%. It is the perfect charging solution even in cloudy environments where the maximum power point of the solar panel fluctuates throughout the day. Multiple Electronic Protections - The controller protects your system with self-diagnostic features that evaluate and protect against reverse polarity, battery overcharge, battery overdischarge, overload, short-circuit, TVS lightning protection, over-power protection, over-temperature protection, and reverse current protection. It helps to charge the battery quickly even in less than ideal weather conditions (e.g. cloudy and rainy days). Automatically Recognizes 12V/24V Voltage - Automatically recognize 12V or 24V DC system voltage, compatible with all kinds of deep cycle batteries: sealed, gel, submerged and lithium batteries. Supports 0V Li-ion battery charging (Li-ion battery activation).LCD display shows solar charging and battery operation information, customized parameters, error codes and user modes. LCD Display and Easy Connection - the MPPT controller is equipped with an LCD display for system operation information and four buttons for menu operation. Simply connect the cables to the solar panel and battery according to positive and negative poles to automatically recognize the voltage and charge the battery, equipped with two USB ports to charge your electronic devices. Excellent Heat Dissipation - The 20A controller is designed with metal casing and dual high-speed intelligent fans for better heat dissipation. Temperature compensation function automatically adjusts charging and discharging parameters to improve battery life.
