Product Q&A

Q:What is the warranty period?

We provide a 1-year warranty for this solar charge controller.

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 higher efficiency, ideal for high-power or low-temperature systems.

Q:What types of batteries are supported?

It supports lead-acid (sealed/open), lithium (LFP/ternary), and gel batteries.

Q:Does it have overload protection?

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

Q:How does it work at night?

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