    Huawei SUN2000 3 kW Single-Phase Solar Inverter

    Exact reference · SUN2000-3KTL-L1

    A compact 3 kW single-phase solar inverter with two MPPTs, optional Huawei high-voltage storage integration and FusionSolar monitoring. The complete PV, AC, metering, storage and backup architecture is confirmed before quotation.

    Rated AC output
    3,000 W single phase

    Defines the inverter output class, not the permitted PV string design.

    PV design allowance
    4,500 Wp recommended maximum

    The exact module count still follows voltage and current limits.

    PV tracking
    2 MPPTs · 1 input each

    Two suitable string groups can be tracked separately.

    MPPT window
    90–560 V

    String operating voltage must remain inside the usable range.

    Input current
    12.5 A per MPPT · 18 A Isc

    Modern high-current modules require explicit compatibility review.

    Do not select a 3 kW inverter from nominal power alone. Confirm string behavior, AC service, grid requirements, battery intent and backup expectations.

    01 · Product role

    What this product does in the system.

    The SUN2000-3KTL-L1 receives DC power from two designed photovoltaic string inputs and converts it into grid-synchronised single-phase AC for the site. It can interface with supported Huawei storage and monitoring equipment, but those functions require separate hardware, compatible firmware and commissioned settings.

    Relevant applications

    • Residential single-phase photovoltaic systems
    • Small professional sites with a verified 220/230/240 V single-phase service
    • Roofs where two suitable string groups benefit from separate MPPT tracking

    Why ReneWave may shortlist it

    • Two MPPTs can manage two separately calculated PV operating points.
    • The compact IP65 enclosure uses natural convection and integrated WLAN.
    • Supported Huawei storage can be added through a separately validated architecture.
    • FusionSolar provides commissioning, monitoring and alarm visibility.

    Built-in capabilities

    Four functions, read before the headline specifications.

    Two PV operating points

    Two MPPTs can track two separately calculated string groups or roof orientations.

    Each MPPT accepts one input with a published 12.5 A maximum current and 18 A short-circuit-current limit.

    Solar DC becomes site AC

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

    Rated output is 3,000 W at 220/230/240 Vac and 50/60 Hz.

    Storage can be added

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

    Battery model, firmware, current limits and backup equipment remain separate confirmation items.

    Commissioning stays visible

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

    Ethernet and cellular paths 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 site loads. The utility remains the AC reference, not an export destination.

    The diagram separates five documented operating states for the Huawei SUN2000-3KTL-L1. Solar can supply protected site loads or charge a compatible Huawei battery. The battery can support site loads, and commissioned settings can permit charging from the utility. During an outage, photovoltaic and battery power reach selected loads only through separate compatible backup switching equipment.

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

    Read the technical explanation

    Two MPPTs for a carefully designed single-phase solar system.

    The SUN2000-3KTL-L1 converts power from two designed photovoltaic string inputs into grid-synchronised single-phase AC. The two trackers can be useful for separately calculated roof orientations or string groups, but they do not remove the need to verify voltage, current, shading and module count.

    Battery and backup boundary

    The inverter provides an interface for supported Huawei Smart String ESS configurations. The battery is separate, and backup supply requires the validated battery architecture plus separate switching equipment such as the Backup Box-B0. Metering, export-control equipment and optional communications dongles are also confirmed from the complete project.

    Selection consequence

    The 3 kW rating is the inverter's nominal AC output. It is not an annual-production estimate and does not by itself approve the photovoltaic array, AC connection or backup design.
