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 difference between PWM and MPPT controllers?

PWM controllers reduce voltage directly with lower efficiency, suitable for small systems. MPPT controllers maximize power output by adjusting operating points, offering higher efficiency for high-power or low-temperature systems.

Q:What types of batteries can be used with this controller?

It supports Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries. Please confirm compatibility with your specific battery type before purchasing.

Q:Does the controller have overload protection?

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

Q:How does the controller work at night?

At night, the controller stops charging and manages battery discharge to the load according to settings, preventing over-discharge.
