Systems using an uninterruptible power supply conventionally receive the battery recharging from utility power. In this system electrical power from the photovoltaic array recharges the batteries of the UPSS when sunlight is available, thus lowering grid power use, & extending UPSS runtime during daylight hours.

Some conventional utility connected facilities require backup electrical power supples. For loads which can tolerate "crossover disconnect-reconnect" supply outage pauses, an engine generator provides complete emergency backup. For critical loads such as computers, security, telemetry, communications & human life support systems, an uninterruptible power supply (UPSS), with its batteries & inverter, provide a continuous "no crossover" emergency backup. The size of the loads & the anticipated utility downtime determine the "on demand" capacity & battery/fuel storage capacity specifications.
