❓ Frequently Asked Questions
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 voltage, current, and capacity.
What is the difference between a PWM controller and an MPPT controller?
PWM controllers are cost-effective for small systems by directly reducing panel voltage to battery voltage. MPPT controllers are high-efficiency, dynamically adjusting the operating point to maximize output, ideal for large systems or cold environments.
What types of batteries can a solar controller be used with?
Most controllers support lead-acid batteries (sealed, open), lithium batteries (LFP, ternary lithium), and gel batteries. Always confirm compatibility with your specific battery type.
Does a solar controller have overload protection?
Yes, most solar controllers feature overload protection. If the load current exceeds the rated value, the controller automatically cuts off the output to protect the entire system.
How does a solar controller work at night?
At night, the controller detects a lack of sunlight, stops the charging process, and manages the battery's discharge to the load based on settings to prevent over-discharging.
