Abstract
The purpose of this work is to introduce a novel system developed to be used as back-up of a conventional UPS, in order to increase its autonomy and to warrant continue operation for long periods of time in the case of a power failure in the public grid. The system is constituted by a conventional UPS connected in parallel to a standalone PV system and a electronic system with facilities to control the charge and discharge of the battery bank of the PV system and to keep the UPS functioning when power cut occur. These elements are interconnected through relays which are activated by digital signals from a control that was developed using virtual instrumentation.
