Product Q&A

Q:What is the main function of a solar controller?

It manages electrical energy between solar panels and batteries, preventing overcharging/over-discharging and optimizing system efficiency.

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 for maximum power, offering higher efficiency for high-power or low-temp systems.

Q:Which battery types are compatible with this controller?

It supports Lead-acid (sealed/open), Lithium (LiFePO4, ternary), and Gel batteries.

Q:Does the controller have overload protection?

Yes, it automatically cuts off output if the load current exceeds the rated value to protect the system.

Q:How does the controller work at night?

It stops charging and manages battery discharge to loads according to settings, preventing over-discharge.
