Product Q&A

Q:What is a solar controller?

A solar controller (or solar charge controller) manages electrical energy transmission between solar panels and batteries. It prevents overcharging/over-discharging, extends battery life, and optimizes system efficiency.

Q:What are the main functions of a solar controller?

Main functions include charging management (preventing overcharging), discharge protection (preventing over-discharging), load control (managing power to devices), and system monitoring (displaying voltage, current, and capacity data).

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

PWM controllers directly reduce panel voltage to battery voltage with lower efficiency, suitable for small-scale or budget systems. MPPT controllers dynamically adjust the operating point to maximize output power, offering higher efficiency for high-power or low-temperature systems.

Q:Which battery types are compatible with this controller?

Most solar controllers, including this one, support multiple battery types such as Lead-acid (sealed/open), Lithium (lithium iron phosphate, ternary lithium), and Gel batteries.

Q:Does the controller have overload protection?

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