Product Q&A

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

PWM controllers directly reduce panel voltage to battery voltage with lower efficiency, suitable for small systems. MPPT controllers dynamically adjust operating points for maximum power output, offering higher efficiency for high-power or low-temperature systems.

Q:What types of batteries are compatible with this controller?

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

Q:Does the solar controller have overload protection?

Yes, most solar controllers include overload protection. If the load current exceeds the rated value, the controller automatically cuts off the 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 the battery from being over-discharged.

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

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