The variety of photovoltaic systems in terms of power, inverter type
(with mains-frequency transformer, with high-frequency transformer or with no
transformer) and type of public grid connection (single-phase, three-phase,
low or medium voltage) requires careful selection of the components by designers
and installers.
The presence of high direct current voltage values, together
with the unique characteristics of photovoltaic systems
(i.e. the system can be powered down only by screening the
solar panels and the strings generate short-circuit currents
with values very close to the currents generated in standard
conditions), make the selection of protection, control and
isolation devices particularly critical. In line with the new
market requirements, ABB developed a complete and reliable
