Product Q&A
Q:What is the difference between PWM and MPPT controllers?
A:
PWM reduces panel voltage to battery voltage with lower efficiency, suitable for small systems. MPPT dynamically adjusts the operating point to maximize output power, offering higher efficiency for high-power or low-temperature systems.
Q:What types of batteries are supported?
A:
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?
A:
Yes, most solar controllers have overload protection. When 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?
A:
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?
A:
Main functions include charging management (preventing overcharging), discharge protection, load control, and system monitoring (displaying voltage, current, and capacity).
