Deye SUN-120K-G03P3 — Three-Phase High-Voltage On-Grid Inverter, 120 kW
The Deye SUN-120K-G03P3 is a utility-grade, three-phase string inverter designed for large commercial and industrial PV plants. It features 8 independent MPPT trackers, a wide DC voltage window, and up to 98.8% maximum efficiency. With an IP65 enclosure and smart thermal management, it provides long-term reliability in outdoor and harsh environments.
Key benefits
-
120 kW AC rated output — ideal for solar farms, industrial rooftops, malls, logistics centers, residential complexes.
-
8 MPPTs with multiple inputs each — flexible string design across different roof faces and tilt angles, maximizing harvest.
-
High conversion efficiency (Max 98.8%, MPPT >99%) — lower losses, better ROI.
-
Wide MPPT range up to 1000 V; PV Voc up to 1100 V — broad compatibility with modern high-voltage modules.
-
Robust protection: IP65 rating, DC/AC protections, Type II SPD, anti-PID, anti-islanding, integrated DC switch.
-
Low acoustic footprint & smart cooling — predictable derating behavior in hot climates (+45…+60 °C).
-
Comms & monitoring: RS-485/RS-232 standard; optional Wi-Fi/LAN/4G/Bluetooth; cloud monitoring ready.
-
Grid functions: 50/60 Hz operation, zero-export capability, VSG features for advanced grid support.
Technical highlights
-
DC side: 8 MPPTs with high allowable input current; nominal DC 600 V with a broad operating window.
-
AC side: three-phase 3L+N+PE; nominal output current around 175–185 A; high power factor, THDi <3%.
-
Safety: comprehensive electrical and thermal protections, arc-free switching, surge protection, fault logging.
-
Mechanical: corrosion-resistant, powder-coated metal housing; outdoor installation ready.
Applications
-
Commercial rooftops (warehouses, retail, office parks).
-
Industrial plants and ground-mount PV assets.
-
Large residential complexes / HOAs with significant contracted power.
-
Sites with heterogeneous arrays (various azimuths/tilts) — 8 MPPTs decouple strings and reduce mismatch losses.
Installation & O&M
-
Standard MC4-compatible connectors on the DC input.
-
Quick commissioning via local interface/app; rich remote monitoring and alerting.
-
Zero feed-in modes for grids with export limits; reactive power control for grid compliance.
-
Recommended preventive maintenance schedule and firmware updates to ensure maximum uptime.
What’s in the box & warranty
-
Deye SUN-120K-G03P3 inverter, mounting kit, documentation.
-
5-year warranty (extensions subject to supply terms and local programs).
