Approximately 100 million euro have been invested in the latter A winning organisation Custom switchboards from Marostica The custom combiners in detail Sardinia: home to one of the most important photovoltaic For two months, simulations were performed to identify the sector over the last three years. Graziella Green Power has skilfully integrated the functions of two The ABB factory in Marostica has purposely modified In field and string control DC switchboards, certified and parks in Italy site time schedule, personnel requirements were analysed In particular, Graziella Green Power has been operating main elements necessary for success of the photovoltaic sector the standard series of combiners (field and string control compliant with IEC 61439-2 Standard, the following ABB In the industrial area of Bolotana in the province of , (it was decided to use local labour instead of the company’s in the photovoltaic sector since 2010, it employs a staff in Italy, with the aim of supplying its customers with complete switchboards in DC) to meet a series of specific needs. components have been used: in the very heart of Sardinia, one of the biggest photovoltaic own resources, despite the obvious difficulties in coordination of over 30 with a turnover of almost 20 million euro and turnkey plants: on one hand, an investment fund to ensure the In fact, combiners had to be compatible with Graziella Green – Gemini series switchboards, size 6. installations in Italy has been constructed (400 000 m2) with and adaptation to different work methods) and every logistical produces approximately 100 MW/h of electricity via its 30 availability of capital and, on the other hand an EPC (Engineering Power proprietary system, which manages remote monitoring – Fuse holders E90 PV at 1000 V. an overall power of approximately 25 MW.
