Product Q&A
Q:What is the main function of a solar controller?
A:
It manages electrical energy between solar panels and batteries, preventing overcharging or over-discharging to extend battery life and optimize system efficiency.
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 for maximum power output, offering higher efficiency for high-power or low-temperature systems.
Q:Which battery types are compatible with this controller?
A:
It supports multiple battery types including sealed and open lead-acid batteries, lithium batteries (LiFePO4, ternary lithium), and gel batteries.
Q:Does the controller have overload protection?
A:
Yes, most solar controllers include overload protection. If load current exceeds the rated value, the controller automatically cuts off output to protect the system.
Q:How does the controller work at night?
A:
At night, it stops charging and manages battery discharge to loads according to settings, preventing the battery from being over-discharged.
