How does a solar controller work at night?

At night, the solar 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 (also known as a solar charge controller) is a device used to manage the electrical energy transmission between solar panels and batteries. Its main functions are to prevent the battery from overcharging or over-discharging, extend the battery life, and optimize the efficiency of the solar energy system.

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 voltage, current, and battery capacity.

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

PWM controllers directly reduce voltage with lower efficiency, suitable for small-scale 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 multiple types including Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries. Users must confirm support for their specific battery type.

Q:Does a solar controller have overload protection?

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