Description (from PDP, plain text)

BLUETTI SolarX 4K Solar Charge Controller Connect a high-voltage solar array to compatible BLUETTI power stations and battery packs, converting 150–500V DC PV input to a DC output below 60V. Supports up to 4,200W of solar input and up to 4,000W DC output for higher-power BLUETTI solar-charging systems. Isolated MPPT charging with app connectivity, CAN communication and built-in electrical protection functions. High-voltage solar charging for compatible BLUETTI systems The BLUETTI SolarX 4K Solar Charge Controller enables suitable high-voltage rooftop or ground-mounted PV arrays to charge compatible BLUETTI portable power stations and battery packs. It accepts solar-array open-circuit voltage from 150V to 500V and provides a regulated DC output of 35V to 58V. This is an installer-oriented component, designed for systems requiring more PV input than a portable power station’s standard solar input can accept. It is compatible with the BLUETTI Apex 300, B300K, B300 and B300S, subject to the correct output cable and system configuration. Key features Up to 4,200W PV input and 4,000W maximum DC output. Single MPPT with stated maximum efficiency of 99%. High-voltage PV input range: 150V to 500V open-circuit voltage; MPPT operating range: 120V to 450V DC. CAN 2.0, Bluetooth and Wi-Fi connectivity for compatible BLUETTI system communication and app-based setup. Output overcurrent, short-circuit, overvoltage, reverse-polarity and insulation-detection protections. Where to use Use the SolarX 4K where a compatible BLUETTI battery or power station needs to be charged from a larger solar array. Typical examples include off-grid buildings, workshops, site accommodation, mobile-support installations and backup-power systems using BLUETTI battery equipment. The controller has IP21 protection and is intended for installation in a dry, sheltered location. It is not a plug-and-play portable accessory: its PV input can reach 500V DC. Installation, commissioning and maintenance must be carried out by qualified professionals or trained personnel.
