ABB PVS800 875 and 1000 kW central inverters

Friday, 12 April, 2013 | Supplied by: ABB Australia Pty Ltd

The PVS800 inverter series from ABB is now available in 875 and 1000 kW sizes. The operating temperature and altitude rating have both been extended and the modular direct current (DC) input design is said to provide greater flexibility for system integrators.

The inverters have a 98.8% maximum efficiency with improved efficiency at partial loads to provide a Euro efficiency rating of 98.6%. This, together with a very low auxiliary power consumption of 700 W for the new sizes at nominal power, results in an inverter with a very high total efficiency.

The inverters have a 45% higher power density compared to earlier ABB central inverters. The inverters offer a wider operational temperature range, up to 50°C at nominal power, and up to 55°C with power derating. This makes the product suitable for hot climate conditions. At lower temperatures, the central inverter provides up to a 20% power overloading capability, up to a maximum power output of 1050 kW and 1200 kW at 25°C for 875 kW and 1000 kW inverters, respectively.

The modular DC input section provides system integrators with a flexible approach. This is helpful when considering the DC cable type and the number of junction boxes needed. The 1000 kW central inverter is available as standard with eight fused busbar inputs and this can be extended up to 16 inputs. Additionally, the DC input section can be provided with integrated DC current measurement per input. As a new feature, PVS800 series inverters are also now able to support grid stability even at night by providing reactive power with the DC input disconnected. The ABB central inverter series, rated from 100 to 1000 kW, is designed for multimegawatt photovoltaic (PV) power plants as well as large PV installations in commercial and industrial buildings.
