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.

Q:What is the difference between PWM and MPPT controllers?

PWM reduces voltage directly with lower efficiency, suitable for small systems. MPPT dynamically adjusts the operating point for higher efficiency, ideal for high-power or low-temperature systems.

Q:What types of batteries can be used?

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

Q:Does the controller have overload protection?

Yes, it automatically cuts off output when 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 the load according to settings, preventing over-discharge.
