Product Q&A

Q:What is the warranty period?

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

Q:What types of batteries are supported?

The controller 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 to protect the system.

Q:What is the difference between PWM and MPPT?

MPPT maximizes output power with higher efficiency, suitable for high-power or low-temp systems, while PWM is lower efficiency and suitable for small-scale or budget-limited systems.

Q:How does it work at night?

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