2 GENERAL DESCRIPTION
2.1 Introduction
The ZIGOR SOLAR XTR3 is a single phrase solar inverter. It is responsible for converting the direct
current generated by photovoltaic panels into alternating current for injection into the electrical power
distribution grid.
The ZIGOR SOLAR XTR3 can be used both to back up consumption and as a system to produce
electricity. In the first case, if the electrical power consumption of the location in which the inverter is
installed is lower than the power consumed by this unit, excess production is delivered to the grid. If this
consumption exceeds production, the energy required to complete the balance is taken from the
electricity grid. In the second case, all the power generated by the equipment is injected into the
electricity grid. In both cases, the appropriate power measurement systems must be installed for each
use.
The installation of the ZIGOR SOLAR XTR3 and its connection to the electricity grid shall be done in
accordance with local regulations and may require the installation of adequate electricity consumption
measuring devices.
The PV inverter only operates when it is connected to the electrical power distribution line and cannot
operate as a stand-alone unit.
