How does a solar controller work at night?

At night, it stops charging and manages battery discharge to the load according to settings, preventing over-discharge.

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 with higher efficiency, ideal 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), and gel batteries.

Q:Does a solar controller have overload protection?

Yes, most solar controllers automatically cut off output when the load current exceeds the rated value to protect the system.
