GeneralInformation
electrical grid. Using cutting-edge technology allows a wide voltage input range (200~1000 V) and
high performance efciency 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 key features
of SOLIVIA 15 TL and 20 TL 3 phase grid-tied solar inverters.
KeyFeatures
● Power Rating: 15/20 kVA
● 3-Phase (3-Phase + N + PE), Grid-tie, Transformerless solar inverter
● Maximum efciency: > 98.0 % (both models)
● Europe efciency: 97.8 % for 15 TL and 20 TL
● Reactive power capability (Cap 0.80 - Ind 0.80)
● Low input current harmonic distortion (THD < 3%) @ full load
● 2 MPP Trackers
● Record up to 30 event logs.
● 5” LCD display
The SOLIVIA 15 TL and 20 TL inverters comply with the latest country regulations and standards.
Please see the 15 TL and 20 TL specication in section 12.1 in the appendix for the complete list
of compliance standards.
1.5 Application&Usage
The operation of the solar inverter is as shown as the gure 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.
1.6 GridInterface
Several different safety systems make up the grid interface:
● VFM (Voltage and Frequency Monitoring)
● RCD (Residual Current Detection)
● DCD (Direct Current Detection)
● Controlling redundant AC relays for each grid phase.
