MPPT 40A 12V/24V LCD Display Solar Controller Automatic Identification Off-Grid System Controller1. Adopt DC DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge
1. Adopt DC/DC conversion technology and MCU technology. It can intelligently adjust the working point of the solar panel array, so that the solar panel array achieves the maximum power output. When external conditions change, the MPPT controller tracks the maximum operating point of solar panels based on MCU theory, so as to improve the efficiency of solar panels and reduce the cost of solar power generation. Compared with ordinary solar charge controllers, MPPT can increase the output efficiency of solar panels by 5% to 30% (the rate of increase in output is affected by the attributes of solar panels, ambient temperature and lighting conditions).

Love it, slim fit, a little tight pulling over the head.
Size: X-Small, Color: Golden Yellow
Overall, this is a really quality sweater. It’s very soft the materials on the thicker side. The color was beautiful. The body fit was perfect, but it was tight fit, pulling it on and off over the head. That being said my child is on the smaller size so it is more of a slim fit overall, I’d recommend sizing up! Other brands he wears a 4T shirt and we purchased an XS (will be getting a small in the future to compare)

Quality item and super comfy.
Size: XX-Large, Color: Light Grey Heather
Got this for my son to take on a field trip in case it got lost it wasn’t one of his expensive ones. Oddly enough it’s so comfy it’s now his favorite hoodie and he wears it all the time and keeps it in his backpack. Holds up well to constant washing.

WARM, not thin material
Size: Small, Color: Blue
Hoodie is comfy, warm and soft. Fits true to size, especially for a child who is a bit small for their age. Holds its' integrity in the wash. VERY happy with this purchase and will be buying more colors in the future.
