Product Q&A

Q:What is the function of a solar controller?

It manages energy transmission between solar panels and batteries, preventing overcharging/over-discharging, extending battery life, and optimizing 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 for maximum power output, offering higher efficiency for high-power or low-temperature systems.

Q:What types of batteries are supported?

Most controllers support Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries. Please confirm compatibility with your specific battery type.

Q:Does the controller have overload protection?

Yes, it automatically cuts off the output when the load current exceeds the rated value to protect the system.

Q:How does the controller work at night?

It stops charging and manages battery discharge to loads according to settings, preventing the battery from being over-discharged.
