New solar PV inverters for large commercial roofs and solar parks

Innovative silicon carbide semiconductors now in inverters with 87 to 150 kilowatts of output power

Neckarsulm, 5 November 2019 – KACO new energy has added five new string inverters to its product range. With outputs between 87 and 150 kilowatts, they are suitable for PV systems on commercial and industrial roofs as well as for ground-mounted solar parks. All new inverters use innovative semiconductor components made of silicon carbide and 1,500 Volt technology. The market launch takes place internationally.

Based on the innovative semiconductor technology of the blueplanet 125 TL3, KACO new energy has developed an inverter series comprising six devices with outputs between 87 and 150 kilowatts.

KACO new energy GmbH has extended its range of string inverters for 1,500 Volt projects by five devices. The blueplanet 87.0 TL3 and blueplanet 92.0 TL3 are suitable for solar power plants on commercial and industrial roofs.

Since 1,500 Volt technology is an emerging trend in the solar roof sector, both inverters are also suitable for solar modules with 1,000 Volts. The blueplanet 92.0 TL3 features a nominal AC voltage of 400 Volts: It can therefore be connected to the low-voltage distribution system without a transformer.

New inverters with 110, 137 and 150 kilowatts of output are available to planners and builders of large, utility-scale solar power plants.

Inverters for the world
The inverters are based on the technology of the blueplanet 125 TL3 which the Germany-based company introduced at the end of 2018. The advantages are mainly due to novel semiconductor components made of silicon carbide (SiC). SiC has more favorable thermal properties than silicon: Power derating at high ambient temperatures only begins at a few degrees above +50 °C.

The lower heat generation of SiC means that a smaller heat sink is used. Thanks to material savings such as these, the inverters have a weight of less than 80 kilograms which makes them comparatively light. The blueplanet 150 TL3 in particular has an extraordinary power density of almost two kilowatts per kilogram.

The new inverters are approved for numerous PV markets worldwide; the blueplanet 110 TL3 is the exception in that it is intended solely for the US market. With a view to North America, all inverters comply with protection class NEMA 4X and thus meet the highest requirements for outdoor installation.

The inverters for special requirements
Other features include: DC surge protection as standard, upgradeable AC protection and optional protection of the communication interfaces; DC disconnection, which is integrated in the XL version of the inverters and implemented in the S version by means of a separate DC-breaker; an optional PID set.

About KACO new energy
KACO new energy, a subsidiary of Siemens AG, is headquartered in Neckarsulm, Germany and one of the world’s largest manufacturers of inverters for grid-feed solar power. The product line-up covers the full power range, from single units designed for a family home up to complete systems for solar parks producing megawatts of electricity. Since 1999, KACO new energy has supplied inverters with a cumulative power output of 13 gigawatts. This offering has been extended to include solutions for PV self-consumption and energy storage, devices for grid management, as well as products and value-added services for utility-scale projects. KACO new energy is the first company in the photovoltaic industry to achieve CO2-neutral production. In 2014, KACO new energy celebrated the 100th birthday of the original parent company which, at the end of the 1930s, was one of first ever inverter manufacturers. More at
