The leading global provider of power and thermal management solutions will demonstrate its expanded solar inverter product line at Intersolar Europe in June.
The new inverters from Delta will enable PV plants ranging in size from a single solar module on a residence all the way up to MW-scale solar parks.
At Intersolar this year Delta will exhibit solar energy solutions that include optimized micro inverters and three-phase transformerless inverters for the residential market, as well as high power and high efficiency commercial solar inverters.
Delta visualizes 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 will be 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 micro inverter, with 260 watt output, is mounted directly under each solar module and is used to harvest the maximum available energy from the PV system. 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.
With the SOLIVIA nano 260, small or even single module solar systems can be implemented. However, existing larger plants can also be expanded when string and micro inverters are combined within the same plant.
The SOLIVIA nano 260 has integrated NS-protection (network and system protection) making it compliant with grid interconnection standards for PV systems in Germany. No extra protection devices are required, making the whole system easier to install and more affordable.
Ease of installation is also ensured thanks to the Amphenol AC cabling system, featuring a trunk and drop cable configuration.
The SOLIVIA nano GW gateway is designed to work together with SOLIVIA nano 260 micro inverters, to monitor and control their operation. Every essential function can be easily controlled from a laptop connected to the SOLIVIA nano GW via a point-to-point wired or wireless connection.
Remote monitoring with the SOLIVIA nano GW is enabled with an internet connection and SOLIVIA Monitor, the system monitoring software from Delta. Real-time performance and energy harvest information from each micro inverter is gathered by the SOLIVIA nano GW via the electrical wiring in the building. The gateway sends the data over the internet to the SOLIVIA Monitor software for viewing online at anytime.
Besides the new micro inverter system, Delta will launch three new transformerless models known as the RPI M6A, M8A and M10A featuring 6, 8 and 10 kW 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%). The asymmetrical loading can increase yield in such applications as east/west roof installations, where modules are orientated in different directions.
The new units are compatible with major types of PV modules and the robust IP65 rated enclosure allows outdoor installation.
Commercial Solutions
The RPI M50A, a 50 kW transformerless three-phase inverter to be introduced will feature 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.
The M50A electronics compartment with its IP65 enclosure rating is designed for outdoor installation, even in harsh environments. An IP65 AC plug is also included in the scope of delivery along with a wall mount bracket that allows the unit to be easily and safely installed onto a wall.
Delta’s broad transformerless inverter series with outputs from 6 to 50 kW, combined with transformer-based products with outputs from 260 W to 11 kW, enable PV plants of all types and sizes to be built that incorporate all types of solar modules.
Andreas Schmidt, Head of Marketing at Delta Energy Systems says, “We are excited to be able to offer customers of all types PV solutions, from a private customer installing a small PV plant on his residence to an industrial customer looking to install a large rooftop system on a business, or a solar park owner with the need for MW-scale PV power generation. In all cases, Delta has solutions for each one that enable optimized PV energy generation.”
The SOLIVIA nano 260 Micro Inverter and the RPI M6A / M8A / M10A / M50A will be available for delivery in select European countries starting in Q3 2014.
