The Swedish-Swiss multinational ABB has released an extension to the central inverter series – a new high-power central inverter. The new PVS800-57B central inverters, with ratings up to 2 megawatts, reduce overall system cost of the solar photovoltaic plants with a compact and easy-to-maintain design. The modular direct current (DC) input design combined with a true mirror design provides superior flexibility for system integrators.
The power density is a 50 percent higher than the ones of the preceding PVS800 models. This reduces installation and container space and lowers transportation costs. The larger inverter power rating also brings considerable savings on the medium voltage side by allowing larger transformers to be used.
The new ABB central inverters offer a wide operational temperature range, up to 50 degrees Celsius at nominal power ratings of 1.645 kilowatts and 1.732 kilowatts, and up to 60 degrees with power derating. This makes the product very suitable for hot climate conditions. (nhp)
