Not a real MPPT solar controller
For DC-DC converter Buck-Boost 5->32V to 1->30V out
I should have researched the original WD2002SJ unit this is derived from, and shown in some of the pictures, which is a battery focused DC-DC power supply. To use as a solar controller, the input becomes the solar panel instead of the battery as designed. Thus the UV-SET becomes the max power point adjustment. It has no automatic adjustment or tracking capacity to adjust for solar, temperature, or any other condition changes.

Hi Sir, thanks for your review! Sorry some wrong product details, I changed it now. This is an amazing buck/boost DC DC converter module for a wide range of applications. Wide range battery fully adjustable charger, advanced solar controller , power supply, CC,CV, UV adjustables , laptop power supply/charger. Example: use a 12V 3S battery pack to power/charge a 19V laptop or a 12V ATX power supply to power old computer! What U see IS what you get WD2002SJ as shown on picture. But careful there are some fake versions out there! At my store IS SURE that U receive the all best original modules! Have a nice day
