1.4 Product Description

The SOLIVIA 15 TL and 20 TL are 3 phase grid-tied solar inverters. These devices convert direct
current (DC) electricity from photovoltaic power collected from PV arrays into 3 phase alternating
current (AC) to feed the excess capacity back to the local mains electrical grid. Using cutting-
edge technology allows a wide voltage input range (200~1000 V) and high performance efficiency
based on a user-friendly operation design. In addition, special DSP (Digital Signal Processor)
design decreases the circuit complication and electronic components. Please note that this device
does not support off-grid function. The following are the features of SOLIVIA 15 TL and 20 TL 3
phase grid-tied solar inverters.

1.5 Application & Usage
The operation of the solar inverter is as shown as the figure 1-1. In order to save energy and
electricity, solar inverters convert the DC input power supplied from the PV array into three-phase
AC output power to the grid.
