Product Q&A
Q:What is a solar controller?
A:
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 is the difference between a PWM controller and an MPPT controller?
A:
PWM controllers directly reduce voltage with lower efficiency, suitable for small systems. MPPT controllers dynamically adjust operating points for higher efficiency, ideal 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 (LFP, ternary), and Gel batteries.
Q:Does a solar controller have overload protection?
A:
Yes, most solar controllers feature overload protection that automatically cuts off output if load current exceeds the rated value.
Q:How does a solar controller work at night?
A:
At night, the controller stops charging and manages battery discharge to the load according to settings to prevent over-discharge.
