    Huawei SUN2000 5 kW Three-Phase Solar Inverter

    Exact reference · SUN2000-5KTL-M1

    A 5 kW three-phase solar inverter with two MPPTs, a bidirectional Huawei high-voltage storage interface and FusionSolar monitoring. The complete PV, AC, metering, storage and selected-load backup architecture is confirmed before quotation.

    Three-phase output
    5,000 W · 3W/N+PE

    Defines the AC output class; it does not approve the site service or PV array.

    PV design allowance
    7,500 Wp recommended maximum

    String voltage and current calculations still control the permitted array.

    PV tracking
    2 MPPTs · 1 input each

    Two suitable string groups can be tracked independently.

    MPPT window
    140–980 V

    Each string must remain in the usable window across expected temperatures.

    Input current
    13.5 A per MPPT · 19.5 A Isc

    High-current modules are not automatically compatible.

    Do not select a 5 kW inverter from nominal power alone. Confirm the three-phase service, PV current, string voltage, battery architecture and backup expectations.

    01 · Product role

    What this product does in the system.

    The SUN2000-5KTL-M1 receives DC power from two designed photovoltaic string inputs and converts it into grid-synchronised three-phase AC for the site. Its bidirectional battery interface can work with supported Huawei high-voltage storage, but the battery, meter, backup switching, protection and communications accessories remain separate equipment.

    Relevant applications

    • Residential three-phase photovoltaic systems
    • Small professional sites with a verified 220/380 V or 230/400 V three-phase service
    • Projects where a supported Huawei high-voltage ESS may be added after exact-model and firmware review

    Why ReneWave may shortlist it

    • Two MPPTs can manage two separately calculated PV operating points.
    • Three-phase output can align with a verified three-phase site architecture.
    • The battery interface supports a documented Huawei storage path without making the battery part of the inverter.
    • FusionSolar supports commissioning, monitoring and alarm follow-up.

    Built-in capabilities

    Four functions, read before the headline specifications.

    Two PV operating points

    Two MPPTs can track two separately calculated string groups.

    Each tracker accepts one string input with a published 13.5 A maximum operating current and 19.5 A short-circuit-current limit.

    Solar DC becomes three-phase AC

    The inverter converts photovoltaic DC into synchronised three-phase AC for protected site distribution.

    Rated output is 5,000 W at 220/380 V or 230/400 V, 3W/N+PE.

    High-voltage storage can be added

    A supported Huawei Smart String ESS can connect through the battery interface after exact-system validation.

    Battery model, firmware, charge/discharge limits, metering and backup switching remain separate confirmation items.

    Commissioning stays visible

    WLAN and RS485 support FusionSolar commissioning, monitoring and alarm follow-up.

    Ethernet and cellular communications require an optional compatible Smart Dongle.

    Inside the energy system

    One inverter. Different energy paths.

    Solar conversion inside the inverter. Storage, external protection and configured load circuits remain separate.

    PV strings pass through both MPPT stages and the inverter to serve protected three-phase site loads. The utility remains the direct AC reference.

    The diagram separates five documented operating states for the Huawei SUN2000-5KTL-M1. Solar can supply protected three-phase site loads or charge a compatible Huawei battery. The battery can support the site, and commissioned settings can permit charging from the utility. During an outage, photovoltaic and battery power reach selected single-phase loads only through a separate Backup Box-B1.

    Active power path Inactive path

    Conceptual operation, not a wiring plan. Separate equipment, protection, firmware and commissioning must be verified.

    Read the technical explanation

    Three-phase solar conversion with a reviewed path to Huawei storage.

    The SUN2000-5KTL-M1 combines two photovoltaic trackers, grid-synchronised three-phase conversion and a bidirectional Huawei battery interface. It does not include the battery, meter, backup switch, external protection or optional communications dongles.

    Current and string design matter

    The recommended 7.5 kWp photovoltaic allowance is not a universal array approval. Each string must remain inside the voltage window and the 13.5 A operating-current limit of its assigned MPPT. The high-current modules currently visible in the Store are therefore not automatically compatible.

    Backup is a selected-load path

    With a validated Huawei ESS and Backup Box-B1, selected single-phase loads can receive backup power up to the documented 3.3 kVA and 15 A limit. This is not unrestricted three-phase whole-site backup.
