Product Q&A

Q:What is a solar controller?

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 are the main functions of a solar controller?

It controls charging to prevent overcharging, protects against over-discharging, manages power supply to loads, and may provide system monitoring for voltage, current, and capacity.

Q:What is the difference between PWM and MPPT controllers?

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?

Most controllers support lead-acid (sealed/open), lithium (lithium iron phosphate, ternary lithium), and gel batteries. Confirm compatibility with your specific battery type.

Q:Does the controller have overload protection?

Yes, most solar controllers include overload protection. If load current exceeds the rated value, the controller automatically cuts off output to protect the system.
