1.1 Proper use
The Sunways AT Solar Inverter is the link
between your solar generator and the
public power grid. The energy from the
connected solar generator is converted to
grid-conformant AC current and fed into
the grid.
Thanks to the HERIC ®
topology with FP
switching, the AT Solar Inverter has a
voltage curve which corresponds to that
of a transformer unit with an earthed
negative terminal, and is generally also
recognized for operation on thin-film
modules.
Solar modules which require earthing of
the positive terminal cannot be operated
with the AT Solar Inverter. If in doubt,
always ask your module manufacturer
about a release!
1.2 Function description
Conversion from direct into alternating
current
The AT Solar Inverter converts the direct
current produced by the solar generator
into alternating current. The alternating
current is then fed into the public power
grid.
