Specifications
Product Description
The Deye SUN-20K G05 Three-Phase Inverter is a 20 kW AC on-grid string inverter with two independent MPPTs that maximizes output on commercial and industrial rooftops. Its wide MPPT window (200–1000 V) and 2+2 string design allow optimization of different sections and string lengths, while the maximum efficiency ≈98.6% and IP65 rating ensure performance, reliability, and low maintenance. It includes zero-export functions (with meter/CT), VSG, and optional anti-PID to protect the generator and comply with regulations.
Main Features
- 2 MPPTs with 2 strings per MPPT (2+2 configuration) for flexible designs.
- Maximum efficiency ≈98.6% and MPPT efficiency > 99%.
- MPPT range 200–1000 V (max. Vdc 1000 V; start-up ≈250 V).
- Current per MPPT: 26 A max.; admissible Isc 39 A per MPPT.
- 3-phase 400/230 V output, nominal power 20 kW, adjustable PF 0.8 inductive ↔ 0.8 capacitive.
- IP65 enclosure and intelligent air cooling for continuous operation.
Advantages or Benefits
- More usable kWh: high efficiency and fast MPPT tracking reduce annual losses.
- Design versatility: two MPPTs with 2 strings each to combine orientations and manage shading.
- Regulatory control: real-time export limitation with RS485 meter/CT.
- Robust operation: IP65, integrated protections, and automatic thermal derating.
- Simple maintenance: remote monitoring (Wi-Fi/4G/LAN/BT) and complete telemetry.
Purpose or Applications
Ideal for three-phase self-consumption in warehouses, businesses, and SMEs, small ground-mounted plants, on-site PPAs, and repowering. The Deye SUN-20K G05 Three-Phase Inverter stands out when high efficiency, export control, and low O&M cost are required.
