        SolaX X1-BOOST-5K-G4 | 5kW X1-BOOST G4 Solar Single-Phase Inverter | MPPT

        The SolaX X1-BOOST-5K-G4 is a 5kW single-phase grid-tied inverter built for modern residential solar systems. With dual independent MPPTs and support for up to 200% PV oversizing, it's designed to get the most from today’s high-power panels. Each tracker supports 16A input current, making it ideal for flexible string layouts with larger modules.

        Delivering up to 98% efficiency and a wide 40–560V MPPT range, it performs reliably across varied conditions. Housed in an IP66-rated enclosure with natural convection cooling, it’s quiet and built to last outdoors. It also includes integrated DC isolation, residual current monitoring, Type II surge protection, optional AFCI, and rapid shutdown support for added safety.

        With smart features like export control, CT/smart meter compatibility, and live SolaX Cloud monitoring, installers can deliver compliant, connected solar systems tailored for Australian homes.

        SolaX X1-BOOST-5K-G4 Features

        • 5kW single-phase output: 5000VA rated AC power for standard residential grid connections
        • Dual MPPT with 16A input: Two trackers (2 × 16A, Isc 22A) for flexible string design and high-current modules
        • 200% DC oversizing: Supports up to 10kW of PV to maximise yield within a 5kW export limit
        • High efficiency: Up to 98% max efficiency with wide 40–560V MPPT voltage range
        • Integrated protection: Built-in DC isolator, RCM, Type II SPD on AC and DC, grid protection and optional AFCI / rapid shutdown support
        • Outdoor rated enclosure: IP66 housing with natural convection cooling for external wall mounting
        • Smart monitoring: RS485 and WiFi / LAN / 4G options for SolaX Cloud, including live data and remote diagnostics
        • Export control ready: CT / meter interface for export limiting and energy management with smart loads

        Where to Use this SolaX X1-BOOST-5K-G4

        • New residential single-phase solar installs: Up to 5kW AC with high-power modules
        • System upgrades: Replacing older inverters while adding extra PV capacity using 200% oversizing
        • Sites requiring export limiting: With remote monitoring and integration with smart energy devices
        • Outdoor wall-mounted inverter positions: Needing IP66 protection and quiet, fanless operation

        (X1-BOOST-5K-G4)

        Yes. Each MPPT accepts up to 16A input current, making it well suited to today’s larger-format, high-current modules.

        The inverter can take up to 200% DC oversizing, allowing significantly more panel capacity than the AC rating to maximise generation throughout the day.

        Absolutely. With dual, independent MPPTs, it can run two strings on different pitches or orientations with optimal tracking on each.

        It supports SolaX Cloud via WiFi, LAN, or 4G (depending on the communicator), offering live data, IV-curve tools, and remote diagnostics.

        It comes with an integrated DC isolator, residual current monitoring, Type II surge protection on both AC and DC, and optional AFCI/rapid shutdown support.

        Yes, Sparky Direct stocks the X1-BOOST-5K-G4 and provides fast, Australia-wide shipping. Bulky surcharges apply.
