New ABB inverter boosts solar performance

The new ABB PVS980 central inverter – an essential component in every solar installation that converts direct current (DC) produced in solar panels into alternating current (AC) for use by electricity grids – allows the amount of incoming solar power connected to a single inverter to be increased by as much as 40%: a dramatic improvement that completely changes the economics of a solar installation. Thanks to its increased power, the PVS980 inverter also means a site needs 30% fewer inverters than previously.

The PVS980 high power 1500 VDC central inverter is capable of processing more incoming DC power from photovoltaic (PV) panels through one inverter, reducing the total number of inverters needed on-site, which helps reduce overall costs across the lifetime of a solar plant. Central inverters are used for applications such as large field installations as well as large arrays installed on buildings and industrial facilities. Originally introduced at the Intersolar exhibition as a concept last year, the PVS980 is now shipping commercially and has already seen strong interest among customers, with a number of pilot projects in place. The new inverter is designed to seamlessly integrate into digital smart grids and operate efficiently, while reducing the carbon footprint of the installation.

ABB engineers have improved the compactness of the device, enabling a power density increase of more than 40% – making it possible to build large power rated inverters in the same physical size. Avoiding external air entering the critical compartments of the inverter, the equipment can operate from below freezing to extreme heat in 100% humidity without jeopardizing functionality. The very wide temperature capability offers full performance without derating at up to 50°C, in a waterproof and dustproof enclosure.
