A new solar power installation is
using ABB’s string inverters to cut
the time needed to achieve a fully
operational system, while providing
more electrical protection than some
competing products.

The installation, for fashion house
David Nieper, is the first in the UK
to use the ABB PVS300 string inverter
and was installed by Greenheart
Energy, a leading system integrators
for renewable energy projects.

The project uses 50kW peak, roof
mounted solar panels. These are the
highest powers that qualify for the

government’s feed-in tariff scheme.

The installation uses six, 8kW string
inverters, four on one roof with
another two on a nearby roof. The
inverters each have three strings of
solar panels, 15 panels per string.

A key advantage of the PVS300 is
its 900V input. More photovoltaic
modules can be connected in series,
which results in higher string power
for the same current. This helps to
reduce cabling power losses and also
cabling size and cost.
