Seamless Solar Compatibility, Supercharged

Meet the world's first 4 kW solar charge controller. The BLUETTI SolarX 4K takes 150–500 V from nearly any rooftop or ground array and converts it into safe, sub-60 V charging for BLUETTI power stations—up to 4,000 W. 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.

Charge Your BLUETTI System, Your Way

SolarX 4K works seamlessly with a wide range of BLUETTI power stations and battery packs, from Apex 300 and AC300 to AC500, B300K, B300, and B300S. Whether you're charging one unit, several at once, or mixing stations with batteries, SolarX 4K delivers safe, efficient, and flexible solar charging tailored to your setup.
