How does a solar controller work at night?

At night, the controller stops charging and manages the battery's 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 (or solar charge controller) manages electrical energy transmission between solar panels and batteries. Its main functions are to prevent overcharging or over-discharging, 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 prevent over-discharging, load control for connected devices, and system monitoring for data like voltage and current.

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

PWM directly reduces voltage with lower efficiency, suitable for small-scale systems. MPPT maximizes 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 (LiFePO4, ternary), and Gel batteries. Users must confirm compatibility with their specific battery type.

Q:Does a solar controller have overload protection?

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