    Huawei SUN2000 15 kW Three-Phase Hybrid Solar Inverter

    Exact reference · SUN2000-15K-MB0

    A 15 kW three-phase hybrid inverter with four PV inputs across two MPPTs and two Huawei storage terminals. Batteries, SmartGuard, metering, external protection, selected backup circuits and optional communications hardware remain separate.

    Three-phase output
    15,000 W · 3W/N+PE

    Defines the rated AC output class; it does not approve the site service or connected loads.

    PV design allowance
    22,500 Wp recommended maximum

    String voltage, per-input current and combined MPPT current still govern the array.

    PV tracking
    2 MPPTs · 4 inputs

    Two inputs per tracker permit designed parallel strings, not four arbitrary strings.

    Storage architecture
    2 LUNA S0/S1 terminals

    The exact batteries, firmware and one- or two-string limits require project validation.

    Backup path
    SmartGuard-63A-T0 · ≤100 ms published

    Backup requires separate compatible switching, commissioned settings and a controlled load design.

    Do not select the 15 kW reference from nominal power alone. Confirm the three-phase service, string allocation, combined MPPT current, battery architecture, backup demand and commissioned grid settings.

    01 · Product role

    What this product does in the system.

    The SUN2000-15K-MB0 converts power from up to four deliberately allocated PV strings into grid-synchronised three-phase AC. Its two battery terminals can manage one or two compatible Huawei LUNA storage strings, while backup requires a separate SmartGuard-63A-T0. None of that separate equipment is included with the inverter.

    Relevant applications

    • Larger three-phase residential and professional solar systems with up to four calculated PV strings
    • Projects planning one or two compatible Huawei LUNA2000 S0 or S1 storage strings
    • Sites requiring selected single-phase backup loads through a separately designed SmartGuard path

    Why ReneWave may shortlist it

    • Four PV inputs can accommodate two strings per MPPT when both the individual-string and combined-tracker limits are satisfied.
    • Two storage terminals support reviewed one- or two-string Huawei LUNA architectures.
    • SmartGuard-63A-T0 provides a documented route to selected single-phase backup loads; three-phase loads remain on the non-backup outputs.
    • FusionSolar keeps commissioning, monitoring and alarm follow-up in one ecosystem.

    Built-in capabilities

    Four functions, read before the headline specifications.

    Four designed PV inputs

    Two MPPTs can each accept two calculated string inputs.

    Huawei publishes 30 A per MPPT with two strings, 20 A with one string and 40 A maximum short-circuit current.

    Solar DC becomes three-phase AC

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

    Rated output is 15,000 W, with 16,500 VA maximum apparent power.

    One or two LUNA strings can be integrated

    Two storage terminals support validated Huawei LUNA2000 S0 or S1 architectures.

    Huawei publishes 21 kW maximum charging with one battery string, 25 kW with two and 16.5 kW maximum discharge.

    Commissioning stays visible

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

    Ethernet and cellular communication require optional compatible equipment.

    Inside the energy system

    One inverter. Different energy paths.

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

    Four designed string inputs pass through two MPPTs and the MB0 to serve protected three-phase site loads. Utility remains the direct AC reference.

    The diagram separates five documented states for the Huawei SUN2000-15K-MB0. Four designed PV inputs feed two integrated MPPTs. Solar can supply protected three-phase site loads or charge one or two compatible Huawei LUNA strings. Storage can support the site, and commissioned settings can permit up to 15 kW of utility charging. During an outage, solar and storage reach selected single-phase backup loads only through a separate SmartGuard-63A-T0; three-phase loads remain non-backup.

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

    Read the technical explanation

    More solar and storage capacity for a deliberately engineered three-phase system.

    The SUN2000-15K-MB0 combines four PV inputs, two trackers, three-phase conversion and two Huawei storage terminals. LUNA storage, SmartGuard, metering, external protection, selected backup circuits and optional communications remain separate equipment.

    Four inputs still require electrical design

    Two strings can share one MPPT only when each string and the combined tracker remain inside Huawei's voltage, current and short-circuit limits. Physical connector count is not compatibility evidence.

    Storage and backup remain complete-system decisions

    One or two compatible LUNA strings can be integrated after exact models, firmware, current limits and commissioning settings are confirmed. With MB0, the separate SmartGuard-63A-T0 backup port supplies selected single-phase loads only; three-phase loads remain on non-backup outputs.
