How does a solar controller work at night?

At night, it stops charging and manages battery discharge to loads 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 controls battery charging to prevent overcharging, protects against over-discharging, manages power supply to loads, and monitors system data like voltage and current.

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

PWM reduces panel voltage directly with lower efficiency, suitable for small systems. MPPT dynamically adjusts for maximum power output, 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), and gel batteries.

Q:Does a solar controller have overload protection?

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