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 role of a solar controller?
A:
It performs charging management, discharge protection, load control, and system monitoring to ensure safe and efficient operation.
Q:What is the difference between a PWM controller and an MPPT controller?
A:
PWM reduces voltage directly with lower efficiency, suitable for small systems. MPPT dynamically adjusts the operating point for higher efficiency, ideal for high-power or low-temperature systems.
Q:What types of batteries can a solar controller be used with?
A:
Most controllers support Lead-acid (sealed/open), Lithium (lithium iron phosphate, ternary lithium), and Gel batteries.
Q:Does a solar controller have overload protection?
A:
Yes, most solar controllers automatically cut off output when load current exceeds the rated value to protect the system.
