LiFePo cells are used for battery storage, connected to a system voltage of 12 V. As a battery management system BMS123 Smart is used, which is fully integrated into PV monitoring. The island system has two 230 V converters with a power of 500 VA at the output. System monitoring is provided by CERBO GX.
