Product Q&A

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

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

Q:What types of batteries are supported?

Most solar controllers support multiple battery types, including lead-acid (sealed/open), lithium (LiFePO4, ternary), and gel batteries.

Q:Does the controller have overload protection?

Yes, most solar controllers have overload protection. When 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 solar controller stops charging and manages the battery's discharge to the load according to settings, preventing over-discharge.

Q:What are the main functions of a solar controller?

Main functions include charging management (preventing overcharging), discharge protection, load control, and system monitoring (displaying voltage, current, and capacity).
