How does a solar controller work at night?

At night, the controller stops charging and manages battery discharge to the load according to settings, preventing the battery from being over-discharged.

Product Q&A

Q:What is a solar controller?

A solar controller manages electrical energy transmission between solar panels and batteries, preventing overcharging or over-discharging to extend battery life and optimize system efficiency.

Q:What is the role of a solar controller?

It performs charging management, discharge protection, load control, and system monitoring to ensure safe and efficient operation of the solar energy system.

Q:What is the difference between a PWM controller and an MPPT controller?

PWM controllers reduce voltage directly with lower efficiency, suitable for small systems. MPPT controllers maximize output power by adjusting the operating point, offering higher efficiency for high-power or low-temperature systems.

Q:What types of batteries can a solar controller be used with?

Most controllers support Lead-acid (sealed/open), Lithium (lithium iron phosphate, ternary lithium), and Gel batteries. Users must confirm compatibility before choosing.

Q:Does a solar controller have overload protection?

Yes, most solar controllers feature overload protection that automatically cuts off output when load current exceeds the rated value to protect the system.
