In this way, the design and operation of an experimental prototype are described, consisting of two photovoltaic systems for self-consumption with energy storage using batteries operating at different voltages. One of them operates at low voltage (Low Voltage Installation, LVI) and the other at high voltage (High Voltage Installation, HVI).
Building-level High Voltage (HV) storage for PV systems is a specific issue for Li-ion technology, which aims to reduce losses when operating at higher voltages. These batteries operate in the range of 200–500 V, as opposed to traditional Low Voltage (LV) systems, which operate at voltages below 100 V, with 48 V being the usual value [ 26 ].
To counter the natural supply–demand imbalance caused by solar energy, standalone solar PV system often include energy storage devices, primarily lead–acid batteries. Due to lead-acid battery limitations, solar systems often have higher operational costs compared to traditional power systems.
