MPPT 5A Solar Panel Regulator Controller Battery Charging 9V 12V 24V Automatic Switch
A part of the review has been auto-translated.
Product came broken and was DOA. The coil broke during shipping as there was only a thin plastic bag and no protection. See images. I guess it is a good product when it works...
It was broken upon delivery. Poorly packed without any packing material under a heavier package (Epever mppt solar charger). So a coil had broken during an unavoidable handling of the package.
Good product, but cannot deliver charging current of 5A, unless there is proper heatsink on the two diodes and the two mosfets. This may also be due to RCS being bigger than 0.04Ω. In any case the existing heatsink is not correctly glued underneath the components, as it touches only partially some of the heated parts. Even worse, the metal heatsink touches the pins of some other components and there is danger of shorts and damage. Furthermore, in my unit, the dual led is soldered the other way around, and as a result, when it charges a battery, the blue led is on, and when the battery gets full, the red led comes on. Nevertheless, it is a good mppt charger. I attach the Charging Profile and its Diagram, taken from CN3722 datasheet.
No damage. fast shipping. item looks good 👍
for a month, did not check
Excellent MPPT solar charger.
посылка пришла в срок, качество проверить пока не могу выломаны конденсаторы (фото прилагаю)
já está funcionando 👍
PCB looks very clean! Nice solder joints and no lose parts.
All right, perfect.
