    Deye SUN 12 kW Three-Phase Low-Voltage Hybrid Inverter

    Exact reference · SUN-12K-SG04LP3-EU

    A 12 kW three-phase hybrid inverter integrating two PV trackers, bidirectional 48 V battery conversion, a selected-load output and one configurable generator port. The battery, BMS, metering, protection and generator remain separate.

    AC output
    12,000 W rated · 13,200 VA maximum

    Continuous phase current, unbalance and surge behavior still require calculation.

    PV design boundary
    24,000 W access · 18,000 W input

    The complete array must satisfy both power limits plus voltage and current checks.

    PV allocation
    2 MPPTs · 3 inputs arranged 2+1

    Three connectors remain grouped behind two trackers and are not three independent channels.

    Battery interface
    40–60 V · 240 A charge/discharge

    The battery, BMS and complete DC path must support the intended current safely.

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

    Phase allocation and selected backup loads must be designed deliberately.

    Do not select this inverter from 12 kW, three-phase output or 48 V alone. Confirm string allocation, battery current capability, BMS protocol, per-phase loads, surge demand, AC service and GEN-port assignment.

    01 · Product role

    What this product does in the system.

    The SUN-12K-SG04LP3-EU receives three designed PV inputs grouped behind two MPPTs, converts solar or battery DC into controlled three-phase AC and can support a separately protected load output. Utility, generator and battery operation still depend on external equipment, protection and commissioned settings.

    Relevant applications

    • Three-phase homes and professional sites requiring higher-capacity solar and low-voltage storage
    • Arrays suited to a calculated two-plus-one PV input allocation across two MPPTs
    • Projects with selected protected loads and a separately engineered generator path

    Why ReneWave may shortlist it

    • Two MPPTs coordinate two separately calculated PV operating groups with a 2+1 input arrangement.
    • The 40–60 V interface publishes a 240 A charge and discharge ceiling.
    • Three-phase output supports documented 100% unbalance, 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 PV groups using three inputs arranged 2+1.

    The trackers publish 26 A + 13 A operating-current and 34 A + 17 A short-circuit-current limits.

    Three-phase solar conversion

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

    Rated output is 12,000 W with 13,200 VA maximum apparent power.

    High-current 48 V storage

    The inverter can charge and discharge a separately selected 40–60 V battery.

    The published charge and discharge limit is 240 A.

    Grid, backup and GEN control

    Dedicated grid, selected-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.

    Six operating states show three designed PV inputs arranged two plus one behind two MPPTs and the Deye 12 kW three-phase hybrid inverter.

    Read the technical explanation

    Three-phase solar, 48 V storage and selected-load backup for higher-demand systems.

    The Deye SUN-12K-SG04LP3-EU combines two photovoltaic trackers, three-phase conversion, a bidirectional low-voltage battery inverter/charger and a selected-load output. Three PV connectors remain grouped behind two MPPTs in a 2+1 arrangement. The complete system still requires the correct battery, BMS, metering, external protection and commissioned settings.

    Functional boundary

    The GEN port is configurable. It cannot be generator input, smart-load output and AC-coupling input at the same time. Unbalanced output capability does not remove the need to calculate phase loads, conductors and protection.
