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.

Easy, great function paper towel holder!
Color: Silver
This paper towel holder is the best I’ve ever had. Extremely easy to Put together - instructions are included but you really don’t need them - just screw the metal tube into the base. It’s heavy enough to hold the paper towels securely and ease to take individual sheets. I have one for quite some time now and just bought this one for my son and daughter-in-law. It comes well packaged and came quickly. Very stable, perfect size and easy to use!

Easy & Functional
Color: Silver
Thanks for the lovely note! This is a nice product. I will say the top ring is shiny chrome while the rest of the product is matte. I'm not overly picky so it's fine I'm my bathroom. Works great with no issues.

sturdy and they work well
Color: Black, Size: with Dishcloth Holder
my husband been complaining we need something in there to put sponges, etc. in and I’ve agreed with him for two or three years now we bought some different things and none of them really worked. They weren’t what I wanted. I saw this and bought it and it’s definitely worth the money. It looks great. It’s easy to install sturdy. It’s going to drain easily and it has one of the top little baskets that you can move to wherever you want it I couldn’t ask for anything better this is going to be definitely what we wanted. I just tried other things that go over the faucet and things like that and they did not look right and they were flimsy so before you buy one of those check this out first if you have enough room by
