The “Elios4you” App allows the user to view the data instantly detected from the solar PV system where Elios4you is installed. This gives the user the chance to manage the building’s energy consumption in a better and more precise way, thus cutting down the electricity bill. Instead, the 4-cloud portal offers a long term analysis, in order to compare the energy produced / consumed during the whole year, and to easily download those information on Excel files directly on your PC. The 4-cloud portal, differently from the App, saves all information and a backup copy independently from the phone / tablet in use, even if the memory is full. Furthermore, the portal can configure up to five mail addresses to receive alarms generated by the error signals or malfunctions of the solar PV plant detected by the control system.
