Huawei SUN2000-330KTL-H1 Smart PV Controller, 330 kW Three-Phase Inverter

The Huawei SUN2000-330KTL-H1 is a three-phase smart PV controller and grid-connected inverter designed for utility-scale solar installations. With a nominal AC power output of 300 kW and maximum apparent power of 330 kVA, it delivers maximum efficiency of ≥99.0% and European efficiency of ≥98.8%. The unit features six independent MPPT trackers supporting up to 28 PV strings at 65 A per tracker.

Built-in intelligence includes Smart Connector-level Detection (SCLD), Smart String-level Disconnection (SSLD), and Smart IV Curve Diagnosis. Protection systems encompass DC and AC surge arresters (Type II), residual current detection, PV-array string fault detection, and DC reverse-polarity protection. The transformerless design operates at nominal output voltage of 800 V, 3-phase + PE, with adjustable power factor from 0.8 LG to 0.8 LD.

Communication capabilities include WLAN with APP, USB, MBUS, and RS485 interfaces for integration with FusionSolar management systems. The IP66-rated enclosure with Smart Air Cooling operates reliably across -25°C to +60°C. Dimensions are 1,048 × 732 × 395 mm with weight ≤112 kg.
