The Solectria XGI 1500-DCG is a Yaskawa Solectria Solar family of inverters. It has four models: XGI 1500-250/250-600-DCG, 225-600-DCG, 200/200-480-DCG and 175-480-DCG. These inverters use a functionally grounded DC negative, which prevents potential induced degradation in PV modules that are prone to it. Yaskawa Solectria applications engineering must review every project's single-line diagram and transformer configuration. A separate transformer specification guide covers compatibility. Every model accepts a maximum DC input of 1500 V. The full-power input range is 860 to 1250 V on the 250 and 225 models and 750 to 1250 V on the 200 and 175 models. The inverters comply with UL 1741 Edition 3, IEEE 1547.1-2020 and IEEE 1547-2018. That covers Normal Operating Performance Category B and Abnormal Operating Performance Category III. You can reach the inverter over Wi-Fi from a smart device or over Ethernet from a PC. It has two interchangeable Ethernet ports in the wire box, and weather stations and data acquisition systems connect by Ethernet. The inverters work with SolrenView monitoring without extra hardware, and third-party monitoring platforms are also supported. The 250 kW DCG model is the inverter used in XGI 1500 PowerRack assemblies, which hold from two to eight units.
