Seamless Solar Compatibility, Supercharged
Meet the world's first 4kW solar charge controller. The BLUETTI SolarX 4K takes 150–500V from nearly any rooftop or ground array and converts it into safe, sub-60V charging for BLUETTI power stations—up to 4,000W. That means faster charging, more stored energy, and reliable power whether you're backing up your home, running an off-grid cabin, or building your own solar farm.
Scalable Solar Power, 4 kW to 12 kW
SolarX 4K lets you decide how much solar power fits your life. Use one unit to cover daily essentials, or scale up to three for your whole home. It connects to your existing solar setup via AC coupling, keeping BLUETTI's DC input ports free for extra panels, so you get more energy, faster, without tying up your system.

Finally, a great pillow!
Size: Standard (Mid Loft), Number of Items: 1
Finally! After so much wasted money on sooooo many pillows, I come across this beauty! This pillow is amazing! I got the medium one, and it’s so perfect. Soft, yet supportive. I’m still surprised at how much I love it!

LOVE IT !
Size: Queen (Mid Loft), Number of Items: 1
I love this pillow. It is just right, firm enough yet soft. My head sinks in and is very comfortable. When I lift my head, the pillow bounces right back into shape. If it lasts, I will buy my family each a pillow as it is wonderful. I woke up with zero neck pain as I typically did when using a standard foam pillow. There is a very light scent yet when I covered the pillow with a protector casing and then a cotton case, there was zero scent. I highly recommend. Especially when compared to the comfort of a very expensive latex pillow my husband uses.

Memory foam could never
Size: Queen (Mid Loft), Number of Items: 1
Wonderfully firm, yet responsive and lightweight. Like a marshmallow for your head and neck. I'm a side sleeper, but this could be great for anyone needing firm but still very soft and comfortable support. Memory foam has nothing on actual latex.

Great pillow! I have two latex pillows now and I don't think I'll ever go back to standard pillows.
