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.

Apex 300+B300K+SolarX 4K

Charge to full in just 1.9 hours with 4,000 W solar, fast enough to keep lights, small appliances, and everyday devices ready when needed.

Note: Data tested by BLUETTI Labs. Actual charging times may vary

2x Apex 300 + 4x B300K + 2x SolarX 4K

8,000 W solar delivers reliable energy for larger appliances, power tools, and extended off-grid living.

3×Apex 300 + 9×B300K + 3×SolarX 4K

Scale to 12 kW, plus 7.2 kW from extra panels for a total of 19.2 kW, enough for heavy loads like central air conditioners, refrigerators, or a full home backup.

This shirt is a cheat code
Color: Black, White, Navy Blue, Light Gray, Size: XX-Large
These shirt fits my body so perfectly! I’m 6’5” 310 pounds but I look 260 pounds. I sweat easily and I’m very sensitive to the material a piece of clothing is made of. This shirt is lightweight, extremely breathable, and feels like silk on the skin. It compliments and accentuates my contours to enhance my physique. I only tried on one and I’ve already ordered 12 more hehe. This is a cheat code.

I Love the collar
Color: Black, White, Navy Blue, Wine Red, Size: Large
Great T-shirt. I can wear this casually with jeans or with a sports coat. The fabric is soft. There is no label in the collar, so you can wear it however you want.

NOT a compression shirt
Color: Black, White, Navy Blue, Wine Red, Size: Large
These are well made with good quality material but are not what I was expecting given the picture. I am an XL and ordered a L because I wanted them to be tight (which they are not.) I decided not to return them because they are good shirts with a reasonable fit, but be advised these are not compression shirts.
