A new central inverter

Share

The new 630 kilowatt inverter has a 98.6 percent maximum efficiency with an improved efficiency at partial loads to provide an EU efficiency of 98.4 percent. This, together with a very low auxiliary power consumption of only 600 watts at nominal power, results in an inverter with a very high total efficiency, as ABB says.

The new 630 kW ABB central inverter offers a wider operational temperature range of up to 45°C at nominal power, and up to 55°C with power derating. This makes the product suitable for hot temperature conditions. At lower temperatures, the ABB central inverter provides up to 10 percent power overloading capability, up to a maximum power output of 700 kW at 25°C.

The ABB central inverter series, rated from 100 to 630 kW, is designed for multi-megawatt photovoltaic (PV) power plants as well as large and medium sized commercial and industrial PV installations. A newly designed DC input section provides system integrators with a modular and flexible approach. This is especially helpful when considering the DC cable type and the number of junction boxes needed.

With the ABB central inverter’s certificates and advanced and flexible grid support functions, it is possible to meet all applicable network connection requirements, regardless of where the project is located, as ABB ensures.
