For over 30 years, SMA has helped hundreds of thousands of people and companies produce and consume energy independently according to their individual needs. In collaboration with our customers and partners, we are helping the people around the world transition to a self-sufficient and decentralized energy supply.

The Sunny Tripower CORE1 is the world’s first free-standing string inverter for decentralized rooftop and ground-based PV systems as well as covered parking spaces. The groundbreaking new design allows reductions in installation time of up to 60% and, at the same time, lowers the total cost of ownership (OPEX).

The CORE1 is the third generation in the successful Sunny Tripower product family and is revolutionising the world of commercial inverters with its innovative design. SMA engineers developed an inverter that combines a unique design with an innovative installation method to significantly reduce installation time and provide all target groups with a maximum return on investment.

From delivery and installation to operation, the Sunny Tripower CORE1 generates widespread savings in logistics, labor, materials and services. With integrated Wi-Fi access for fast commissioning, up-to-date plug-and-play communication and smart grid support functions, PV installations are quicker and easier to complete than ever before.

Having the right products is only the beginning. World Technology also offers customers a high level of in-field support, including engineering and site planning, PV product validation, and installation training at the jobsite. World Technology can also help you to design a PV system and can work with your EPCs to make sure all technical parameters are met and all equipment arrives at the jobsite ready to be installed with every nut, bolt, and cable necessary for a smooth installation.

ABOUT SMA:
People living around the world are using intelligent SMA technology to transform their houses into smart homes. By integrating storage systems, the electricity generated from rooftop systems can be used in the evening as well. Industrial and commercial companies are installing PV systems, together with our highly efficient inverters, on their buildings to reduce operating costs by producing cost-efficient solar power.

In countries with high levels of solar irradiation, large PV power plants equipped with SMA system technology are providing more and more people with rapid access to a sustainable and inexpensive electricity supply – and thereby to greater prosperity and economic development. Industrial consumers who struggle with regular power outages or who have no access to the utility grid at all are no longer dependent on expensive diesel fuel for a reliable and uninterrupted electricity supply. With the SMA Fuel Save Solution, they can turn their diesel generators into photovoltaic diesel hybrid systems, thus saving money and reducing CO2 emissions.

Even after the PV systems are commissioned, SMA customers worldwide can rely on SMA and their comprehensive range of services, which ensure that their photovoltaic systems are operating cost efficiently at all times.
