Product Q&A

Q:What is the main function of a solar controller?

It 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 difference between PWM and MPPT controllers?

PWM reduces panel voltage to battery voltage with lower efficiency, suitable for small systems. MPPT dynamically adjusts the operating point to maximize power, offering higher efficiency for high-power or low-temperature systems.

Q:Which battery types are compatible with this controller?

Most solar controllers support multiple types including Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries. Please confirm support for your specific battery type.

Q:Does the controller have overload protection?

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

Q:How does the 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.
