SOLIVIA inverters are available in various outputs from 2 kW to 30 kW. Broad input voltage ranges; the option of interior or exterior installation; compatibility with the most common photovoltaic modules; and durable design make Delta inverters the first choice for professional installers.

Many residential roofs in Europe are oriented along an east-west axis; to maximize this potential, SOLIVIA 10 TL, 15 TL, 20 TL and 30 TL inverters are equipped with an innovative, asymmetrical direct current input, allowing for optimal planning of these systems using just one inverter. The two MPP trackers can be configured at ratios of one-third to two-thirds, or 50/50. For example, a single SOLIVIA 10 TL allows for optimal operation at any time of day for a 14 kW system with 7 kW installed on the east and west roofs.
