Delta at Intersolar 2011: Premiere for the 4th generation of SOLIVIA solar inverters and SOLIVIA monitor

Teningen (ots) - Delta Energy Systems (Germany) GmbH showcases for
the first time the new generation of the SOLIVIA solar inverters at
the leading trade show in Munich. From June 8-10 trade show visitors
have the possibility to learn more about the latest product
highlights and innovations from Delta.

Delta presents multiple new products at the upcoming Intersolar
show. The current European SOLIVIA EU G3 inverters will be replaced
from next year on by the SOLIVIA EU G4 models. These models will be
compliant with the latest low-voltage directive (VDE AR N 4105) as
well as with the mid voltage directive (BDEW) and stabilize the grid
with static voltage stability, dynamic grid support (fault-ride-
through) and power reduction. Improvement of the grid stability is an
important key factor for the future of Solar Energy.

SOLIVIA 11 EU G4 TR - The new three-phase Model with Peak
Efficiency

The SOLIVIA 11 EU G4 TR is a three-phase high efficiency
transformer-based string inverter with an output power of 11 kW and a
peak efficiency of 96.5 %. The model complements the existing SOLIVIA
string inverter product line with an output power ranging between 2.5
and 5 kW. The wide input voltage range of 400 V up to 900 V as well
as the wide operating temperature ranges between -25 °C and +70°C
provide ultimate flexibility for the complete PV installation.

All European string inverters of the fourth generation are
appealing due to new features like a USB communication interface for
realizing firmware updates. The new seamless casing with the
integrated heatsink ensures robustness and a longer product lifetime.

SOLIVIA Monitor - The new Monitoring Solution from Delta

Delta showcases its own monitoring solution - SOLIVIA Monitor -
compatible with the European, North American and Asian-Pacifc SOLIVIA
String Inverter Models from Delta. The solution is offered free of
charge to the customers and provides an easy online portal especially
designed for installers and end customers. The system includes a
gateway, database and the web application. Real-time and historical
data reports can be created and downloaded to the computer.
Furthermore, automated alerts inform the operator of potential
problems and ensure the return of the solar investment.

Visit Delta at the Intersolar from June 8-10 in hall B4 at stand
460.
