✦ Synopsis
In building-integrated grid-interactive photovoltaic (P V) systems, the P V array is typically connected to the utility grid through a PV inverter. As an alternative to this, coupling the PV array to the DC bus of an uninterruptible power supply (UPS) system has previously been proposed. Here, it is reconfirmed that the PV array can be directly coupled to a standard 08the-shelf on-line UPS device. Compared to a typical grid-connected PV system, P V-UPS configuration makes use of an existing infrastructure ojlen found in commercial and institutional buildings and may, in favourable conditions, give a significant increase of system performance in terms of economic return on the P V investment.
