Delta showcased its latest solar energy solutions at the leading solar industry event: Intersolar

From June 4–6, 44,000 visitors flocked to Messe München, where Intersolar Europe and the electrical energy storage (ees) exhibition were taking place simultaneously.

Covering eight halls and the outdoor exhibition area, the range of exhibits attracted visitors from 145 different countries this year, representing a further increase in the percentage of international guests.

Compared to last year’s Intersolar the industry is cautiously optimistic about the further market development. The technology industry trends are self consumption and smart energy management. That was underlined by over 250 Exhibitors that showed energy storage solutions at the show.

Delta exhibited solar energy solutions that included optimized micro inverters and three-phase transformerless inverters for the residential market, as well as high power and high efficiency commercial solar inverters. Delta visualized a clean energy future where everyone can enjoy the benefits of renewable energy and energy savings. With the introduction of new solar inverter products for home owners with smaller power generation goals, to business owners requiring MW-scale power generation, Delta is providing solutions that help everyone meet their energy goals in a smart and eco-friendly way.

Residential Solutions

A highlighted solution for residential PV applications was the SOLIVIA nano 260 micro inverter and SOLIVIA nano GW gateway. With the new micro inverter from Delta every solar module in a PV system gets its own inverter. The devices are ideal for situations where there may be partial shading or complicated roof structures. Since each micro inverter is working independently to seek out the optimum working point of its connected module, irregardless of shading effects on other nearby modules, a continuous and high level of energy can be provided from the entire system.

Besides the new micro inverter system, Delta launched three new transformerless models featuring 6, 8 and 10 kVA power outputs respectively. The new three-phase solar inverters are designed for residential or small commercial applications and feature a high max. efficiency up to 98.5 %. Since all three models feature a compact design and low weight for their power class, installation is greatly simplified. For the system planner, maximum flexibility is ensured thanks to a wide input voltage range of 200 – 1000 V and 2 MPP trackers that support asymmetrical loading (33/67%).

Commercial Solutions

The RPI M50A, a 50 kVA transformerless three-phase inverter features the largest output power in the Delta product line, making it an outstanding choice for commercial-scale PV systems. The PV inverter features a very high max. efficiency of 98.6 % and exceptional power density-to-size ratio. A wide input voltage range of 200 – 1000 V, coupled with 2 MPP trackers provide maximum flexibility in system design and maximum yield. To further simplify the installation process and provide added cost savings, the M50A ships with integrated and replaceable AC and DC-side SPDs (surge protection devices) as well as integrated string fuses. The extra costs of external protection devices and enclosures are avoided and more efficient use of limited installation space is also an added benefit.
