    Deye SUN 20 kW Three-Phase Low-Voltage Hybrid Inverter

    Exact reference · SUN-20K-SG05LP3-EU-SM2

    A 20 kW three-phase hybrid inverter integrating two PV trackers, two low-voltage battery inputs, selected-load output and one configurable generator port. The batteries, BMS, metering, protection and generator remain separate.

    AC output
    20,000 W rated · 22,000 VA maximum

    Service capacity, continuous current, phase allocation and surge behavior still require calculation.

    PV design boundary
    40,000 W access · 32,000 W input

    The complete array must satisfy power, voltage, current and clipping checks.

    PV allocation
    2 MPPTs · 4 inputs arranged 2+2

    Four connectors remain grouped behind two trackers and are not four independent channels.

    Battery interface
    2 inputs · 40–60 V · 350 A aggregate

    Both battery paths, BMS records, conductors and protection must support the intended operating current.

    Three-phase behavior
    100% unbalanced · max 50% rated per phase

    Selected loads and each phase must be designed deliberately.

    Do not select this inverter from 20 kW, three-phase output or 48 V alone. Confirm string current, battery and BMS behavior, AC service, phase loads, surge demand, pass-through current and GEN-port assignment.

    01 · Product role

    What this product does in the system.

    The SUN-20K-SG05LP3-EU-SM2 receives four designed PV inputs grouped behind two MPPTs, converts solar or battery DC into controlled three-phase AC and coordinates a separately protected load output. Utility, generator and storage operation depend on separate equipment, protection and commissioned settings.

    Relevant applications

    • Higher-demand three-phase homes, hospitality and professional sites requiring coordinated solar and 48 V storage
    • Arrays suited to four designed string inputs grouped two per MPPT
    • Projects with deliberately selected protected loads and a separately engineered generator path

    Why ReneWave may shortlist it

    • Two MPPTs coordinate two separately calculated operating groups with two inputs each.
    • Two 40–60 V battery inputs support a published 350 A aggregate charge/discharge ceiling.
    • The three-phase output publishes 100% unbalanced operation, with each phase limited to 50% of rated output.
    • The configurable GEN port can perform one commissioned role at a time.

    Built-in capabilities

    Four functions, read before the headline specifications.

    Two calculated PV operating points

    Two MPPTs track two separately calculated groups using four inputs arranged 2+2.

    Each tracker publishes 36 A operating and 54 A short-circuit-current limits.

    20 kW three-phase conversion

    Available PV or battery power is converted into controlled three-phase AC.

    Rated output is 20,000 W with 22,000 VA maximum apparent power.

    Dual-input 48 V storage

    Two inputs connect a separately validated 40–60 V battery architecture.

    The published aggregate charge and discharge limit is 350 A.

    Grid, backup and GEN control

    Grid, protected-load and configurable GEN interfaces coordinate valid operating states.

    The GEN port is assigned one commissioned function at a time.

    Inside the energy system

    One inverter. Different energy paths.

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

    PV passes through two MPPTs and the inverter to serve selected protected three-phase loads.

    The GEN port is configured for one role at a time. This diagram shows generator input only in Generator support mode.

    Read the technical explanation

    Higher-output three-phase solar, 48 V storage and selected-load backup.

    The Deye SUN-20K-SG05LP3-EU-SM2 combines two photovoltaic trackers, three-phase conversion, two low-voltage battery inputs and a protected-load output. Four PV connectors remain grouped behind two MPPTs. The complete system still requires validated storage, BMS records, metering, protection and commissioned settings.

    Functional boundary

    The GEN port is configurable and performs one role at a time. Two battery inputs do not establish universal battery compatibility, and unbalanced output does not remove the need to calculate phase loads, conductors and protection.
