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 a PWM controller and an MPPT controller?

PWM controllers directly reduce voltage with lower efficiency, suitable for small systems. MPPT controllers maximize output power 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?

Most solar controllers support multiple types including Lead-acid (sealed/open), Lithium (LFP, ternary), and Gel batteries.

Q:Does the solar controller have overload protection?

Yes, most solar controllers include overload protection that automatically cuts off output if the load current exceeds the rated value.

Q:How does the solar controller work at night?

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