Product Q&A
Q:What is a solar controller?
A:
A solar controller (or solar charge controller) manages electrical energy transmission between solar panels and batteries. Its main functions are to prevent battery overcharging or over-discharging, extend battery life, and optimize solar energy system efficiency.
Q:What is the role of a solar controller?
A:
It performs charging management to prevent overcharging, discharge protection to extend battery life, load control for connected devices, and system monitoring for data like voltage and current.
Q:What is the difference between a PWM controller and an MPPT controller?
A:
PWM controllers directly reduce voltage to battery voltage 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 a solar controller be used with?
A:
Most controllers support multiple types including Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries. Users must confirm support for their specific battery type.
Q:Does a solar controller have overload protection?
A:
Yes, most solar controllers feature overload protection. When load current exceeds the rated value, the controller automatically cuts off output to protect the system.
