Product Q&A
Q:What is a solar controller?
A:
A solar controller manages electrical energy transmission 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 controllers reduce panel voltage directly with lower efficiency, suitable for small systems. MPPT controllers maximize output power by adjusting operating points, offering higher efficiency for high-power or low-temperature systems.
Q:What types of batteries can be used with this controller?
A:
It supports multiple battery types including sealed and open lead-acid batteries, lithium batteries (lithium iron phosphate, ternary lithium), and gel batteries.
Q:Does the solar controller have overload protection?
A:
Yes, most models include overload protection that automatically cuts off output when load current exceeds the rated value to protect the system.
Q:How does the controller work at night?
A:
At night, the controller stops charging and manages battery discharge to connected loads according to settings, preventing over-discharge.
