TENINGEN, Germany -- The high-frequency, grid-connected SOLIVIA [Solar Inverters for Versatile and Intelligent Applications] solar inverters from Delta Energy Systems (DES) are suitable for all commonly used solar modules and for thin-film and rear-side contact PV modules. Delta says this is due to the product's implemented galvanic isolation and the integrated DC wiring box, which accommodates either positive or negative DC grounding.
All models incorporate an integrated lockable DC disconnect that is mandated by many local authorities, notes the company, leading to reduced installation efforts and expenses, as the need for an external 600 VDC disconnect switch is eliminated.

According to the company, the new line of solar inverters, designed especially for the North American market, operate within a wide temperature range -- up to 50 degrees C with full power output (without derating). This ensures high yields even for installations in warmer climates. With intelligent MPP tracking, the inverters get maximum energy harvesting from the solar modules under all operating conditions.
The SOLIVIA inverters feature a lightweight, compact design and simplified installation via a provided mounting plate. In addition, the SOLIVIA inverters are NEMA4 / IP65 enclosure rated for dust-tight operation, as well as completely safe to touch and protected against moisture, allowing them to be installed indoors as well as in protected outdoor areas. All relevant status messages and stored data can be recalled either via an integrated display or via a PC connected to the RS485 communication interface.
The SOLIVIA solar inverters produced for the North American market will be presented for the first time to the public at the Intersolar tradeshow in San Francisco, July 13-15. Four new models - SOLIVIA 2.5, 3.3, 4.4 and 5.0 NA G3 - with a nominal output power ranging from 2.5 to 5.0 kW -- complement the already available European solar inverter product line from Delta. Production will begin in the fourth quarter of 2010.
