How does the controller work at night?

At night, the solar controller stops charging and manages the battery's discharge to the load according to settings, preventing the battery from being over-discharged.

What is the minimum order quantity?

The Minimum Order Quantity (MOQ) is 2000 units.

What are the payment terms?

Payment terms include LC, T/T, Western Union, Small-amount payment, PayPal, and D/P.

Product Q&A

Q:What is the warranty period?

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

Q:What certifications does the product have?

The product is certified with ISO and CE standards.

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-temperature systems.

Q:Which battery types are supported?

Most solar controllers support lead-acid (sealed/open), lithium (lithium iron phosphate/ternary), and gel batteries.

Q:Does the controller have overload protection?

Yes, most solar controllers have overload protection. When load current exceeds the rated value, the controller automatically cuts off the output to protect the system.
