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
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
