ABB’s central inverter series,
PVS800, is now available in 875 and
1000kW versions. The central
inverters are said to
reduce overall system
cost and to have higher
total efficiency with a
compact and easy-tomaintain
design. The
operating temperature and
altitude rating are extended and the
modular direct current input design
provides greater flexibility for system
integrators.
The PVS800 has a 98.8%
maximum efficiency. This figure is
improved at partial loads to provide
a Euro efficiency rating of 98.6%.

The inverters have very low auxiliary
power consumption of only 700W at
nominal power, which further
contributes to a high total efficiency.

With a 45% higher
power density, compared
to ABB’s earlier versions,
the PVS800 is one of the
most compact inverters
on the market by
footprint and volume per kW. This
reduces installation and container
space and cuts transportation costs.
