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 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 to prevent overcharging, discharge protection to safeguard battery life, load control for connected devices, and system monitoring for voltage and current data.

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 dynamically adjust the operating point 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. Users must confirm compatibility with their specific battery type.

Q:Does a solar controller have overload protection?

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