The LiTime 20A solar charge controller features a comprehensive design that includes several key components for easy use and installation. It has an LCD screen for monitoring, panel mounting holes, and a USB port (5V 1A) for charging mobile devices. The controller also includes operation buttons, DC load terminals, battery terminals, and solar terminals for connectivity. Additionally, it comes with bracket holes for secure mounting, wall mounting posts and bolts, and the necessary screws and accessories for installation. This thoughtful layout ensures a user-friendly experience while maintaining efficient functionality.
The LiTime 20A solar charge controller offers flexible installation options, allowing for either panel mounting or wall mounting. When installing, it's important to choose a vertical surface that is protected from direct sunlight, high temperatures, and moisture to ensure optimal performance. Additionally, ensure there is good ventilation around the unit to facilitate effective heat dissipation. This versatility in installation allows you to integrate the controller seamlessly into your energy system setup.
The LiTime pwm solar charge controller offers multiple layers of protection to ensure safe and reliable operation. Key safety features include battery over-discharge protection, which prevents excessive depletion of battery power, and battery over-voltage protection, which safeguards against voltage spikes. Additionally, the pwm includes load short circuit protection to prevent electrical faults, overheating protection to manage temperature levels, and solar over-voltage protection to maintain safe charging conditions. This comprehensive array of safeguards makes the LiTime solar system a secure choice for powering your energy needs, whether in a camper, RV, or off-grid setup.
The LiTime solar charge controller features adjustable settings for battery type and voltage, ensuring compatibility with different battery systems. Users can select the appropriate battery type—Lithium (Li), Flooded (FLD), Gel (GEL), or Sealed (SEL)—to match their setup, with 12V as the default option. This functionality supports automatic recognition of 12V/24V battery systems, providing flexibility for various applications. Proper configuration helps optimize performance and extends the lifespan of your battery setup, making it ideal for both residential and mobile energy solutions.

FAQ
Q: What is the main difference between MPPT and PWM charge controllers?
A:
The main difference is in how they regulate the charging process. MPPT controllers track the maximum power point of the solar array to extract the most power, while PWM controllers simply regulate the voltage to the battery. Can read on MPPT VS PWM for more information.
Q: What are the advantages of using a PWM solar controller?
A:
PWM controllers are cost-effective, simple to use, and reliable. They are suitable for smaller solar power systems and are generally more affordable compared to MPPT (Maximum Power Point Tracking) controllers.
Q: Can a PWM solar controller be used with different types of batteries?
A:
Yes, PWM controllers are compatible with various types of batteries, including lead-acid, gel, and AGM (Absorbent Glass Mat) batteries. They are designed to adjust the charging parameters based on the connected battery type.
