Delta Unveiling New SOLIVIA Solar Inverters

June 27, 2010 by Jeff Shepard

Delta Energy Systems GmbH is readying to unveil its SOLIVIA solar inverters produced for the North American market. 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 complements the company’s already available European solar inverter product line. Production will begin in the fourth quarter of 2010.

The high-frequency grid-connected SOLIVIA solar inverters from Delta are suitable for all commonly used solar modules – also for thin-film and rear-side contact PV modules – due to the implemented galvanic isolation and the integrated dc wiring box that accommodates either positive or negative dc grounding. All models incorporate an integrated lockable dc disconnect which is mandatory for many local authorities, leading to reduced installation efforts and expenses as it eliminates the need for an external 600Vdc disconnect switch. The high-frequency grid-connected solar inverters for the North American market operate within a wide temperature range, up to 50°C with full power output (without derating). This ensures high yields even for installations in warmer climates. With its 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 by using the unique mounting plate that is provided. In addition, the SOLIVIA inverters are NEMA4/IP65 enclosure rated for dust-tight operation, completely safe to touch and protected against moisture, allowing the models to be installed indoors as well as in protected outdoor areas. All relevant status messages and stored data can be recalled either via the integrated display or via a PC connected to the RS485 communication interface.
