The BL-SOLARX-4K is a high power MPPT solar charge controller designed to integrate with Bluetti power stations and battery systems. Accepts 4000W solar power from series-connected panels with a wide voltage range and efficiently converts that power to a safe voltage to charge the system's batteries, given its advanced MPPT technology.

Features monitoring and control via app (Bluetooth/Wi-Fi), allowing for real-time viewing of solar production and charging status. These characteristics make it ideal for use scenarios such as solar home installations or off-grid installations with existing solar panels.
