ABB's central inverter series, PVS800, is now available in larger sizes.
The new 875 and 1000 kW central inverters reduce overall system cost and have higher total efficiency, according to ABB.
A 45 per cent higher power density compared to earlier ABB central inverters makes this one of the most compact inverters on the market by footprint and volume per kW.
The new 875 and 1000 kW ABB central inverters offer a wider operational temperature range, up to 50°C at nominal power, and up to 55°C with power derating, making it suitable for hot climate conditions.
At lower temperatures, the central inverter provides up to a 20 per cent 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 1000 kW central inverter is available as standard with eight fused busbar inputs, which 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 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 multi-megawatt photovoltaic (PV) power plants as well as large PV installations in commercial and industrial buildings.
