What is a solar controller?
A solar controller (also known as a solar charge controller) is a device used to manage the electrical energy transmission between solar panels and batteries. Its main functions are to prevent the battery from overcharging or over-discharging, extend the battery life, and optimize the efficiency of the solar energy system.
What is the role of a solar controller?
It handles charging management to prevent overcharging, discharge protection to preserve battery life, load control for connected devices, and system monitoring for data like voltage and capacity.
What is the difference between a PWM and an MPPT controller?
PWM controllers directly reduce panel voltage to battery voltage and are suitable for smaller budgets. MPPT controllers maximize output power by dynamically adjusting the operating point, offering much higher efficiency for high-power systems.
What types of batteries can be used?
Most controllers support lead-acid batteries (sealed, open), lithium batteries (LiFePO4, ternary lithium), and gel batteries. Always confirm compatibility with your specific battery type.
Does the controller have overload protection?
Yes, most solar controllers include overload protection. If the load current exceeds the rated value, the controller will automatically cut off the output to protect the system.
How does a solar controller work at night?
At night, the controller stops charging and manages the battery's discharge to the load according to your settings, ensuring the battery is not over-discharged.
