Deye SUN-135K-G — an industrial string inverter with a capacity of 135 kW, featuring 8 independent MPPT trackers and maximum efficiency of up to 98.8%. The device is designed for large commercial solar power plants and microgrids, supports Zero Export and VSG (virtual generator), features a full set of protections, and complies with leading European grid standards.
The wide input range MPPT 200–1000 V (starting — 600 V) simplifies array design, while IP65 protection rating, intelligent air cooling, and an extended temperature range –20°C to 60°CV) simplifies array design, while IP65 protection rating, intelligent air cooling, and an extended temperature range of –25…+60 °C ensure stable outdoor operation.
Key Benefits
- 8 MPPT with multiple inputs — flexibility for various orientations and shading.
- Efficiency up to 98.8%, European standard — ≈98.2% — minimal energy losses.
- Zero Export and VSG — integration into Smart Grid and microgrids.
- Type II SPD on DC/AC, insulation monitoring, protection against short circuits, overheating, and current leakage.
- Anti-PID (optional) — protection of modules against degradation.
- Cloud/local monitoring: GPRS/Wi-Fi/Bluetooth/4G/LAN (optional) + RS485/RS232.
- Compact housing: 1006 × 516 × 325.5 mm, weight ≈103 kg.

- Max. output current: up to ≈204.6 A (at 380 V) / ≈195.7 A (at 400 V)
- Efficiency: max. 98.8%; MPPT >99%
- Protection rating: IP65; type — non-insulated; cooling — intelligent air cooling
- Dimensions / weight: 1006 × 516 × 325.5 mm / ≈103 kg
- Interfaces: RS485/RS232; monitoring: GPRS/Wi-Fi/Bluetooth/4G/LAN (opt.)
Features
Thanks to 8 MPPT, the inverter easily handles fields where strings have different orientations/tilt angles. A full set of protections (SPD Type II DC/AC, ground and insulation monitoring, UZO, anti-islanding) enhances reliability and safety. Optional smart grid monitoring simplifies the management of large stations, while the Zero Export and VSG functions enable integration into power-controlled microgrids.
Applications
- Large commercial/industrial solar power plants (rooftops, ground-mounted fields, carports).
- Microgrids with export limitation and VSG support.
- Energy-intensive facilities: warehouses, agricultural enterprises, manufacturing, logistics.
