Felicity Solar 120A Solar Charge Controller MPPT


Felicity Solar 120A Solar Charge Controller MPPT


Solar Charge Controller: A solar charge controller, also known as a solar regulator or solar panel controller, is a critical component in a solar photovoltaic (PV) system. Its primary function is to regulate and manage the power flowing from solar panels to the battery bank. A solar charge controller ensures that the battery bank receives the optimal amount of charge from the solar panels while preventing overcharging and damage to the batteries.

Maximum Power Point Tracking (MPPT): MPPT is an advanced technology used in certain types of solar charge controllers. It allows the charge controller to track and find the “maximum power point” of the solar panel’s voltage-current curve. By continuously adjusting the operating voltage and current, an MPPT charge controller can extract the maximum available power from the solar panels under varying weather conditions and solar irradiance levels.

  1. Charging Capacity: The charge controller can handle a charging current of up to 120 amps, making it suitable for medium to large solar PV systems.
  2. MPPT Technology: It incorporates MPPT technology to optimize the solar panel’s output and improve overall system efficiency.
  3. Battery Compatibility: The charge controller is designed to work with different types of batteries, such as lead-acid, lithium-ion, or gel batteries.
  4. Voltage Regulation: The controller ensures that the voltage supplied to the battery bank remains within safe and optimal levels to prevent overcharging and extend battery life.
  5. LCD/LED Display: It may come with a digital display to provide real-time information about system status, charging current, battery voltage, etc.
  6. Multiple Protection Features: The charge controller should have built-in protection mechanisms, such as overcharging, over-discharging, short-circuit, reverse polarity, and temperature protection.
  7. Communication Interface: Some advanced controllers offer communication ports (e.g., RS-485, USB) to connect with a monitoring system for data logging and remote monitoring.
  8. Temperature Compensation: Temperature compensation feature adjusts charging parameters based on the battery temperature, improving overall charging efficiency.
  9. Fan Cooling: In high-power applications, the charge controller might be equipped with a cooling fan to prevent overheating during operation.
  10. Mounting and Installation: The design should facilitate easy mounting and installation, whether it’s for a standalone solar system or integration with other components.
