A PV system for a Spanish cereal producer Fronius and Victron Energy have partnered ©Fronius International GmbH

on a project involving cereal producer CETOSA (Cereals Torremorell SA), based in Algerri in the Spanish province of Lleida — a remote region where an unrestricted power supply cannot always be guaranteed. Many consumers in such regions rely solely on energy produced by diesel generators; however, these generators are expensive to maintain and have high emission levels. In order to optimise the costeffectiveness of its business and ensure a continuous power supply for production operations, CETOSA opted for solar power produced by its own photovoltaic (PV) system. The company turned to solar technology from Fronius and Dutch energy specialist Victron Energy to benefit from their expertise in efficient solar systems. “The aim of this project was to upgrade CETOSA’s 82 kW photovoltaic system,” said Francisco Heredia, technical advisor at Fronius Spain. Three Fronius Symo inverters were installed for this purpose and the energy generator was

connected directly to the microgrid — a regional, self-contained power distribution network. “Our inverters have a special set-up for this purpose, with various functions to ensure stable microgrid operation,” added Heredia. In order to store the electricity generated and so provide a continuous power supply, Fronius made its inverters compatible with technology from Victron
