opographic diagram of the equipment
The diagram summarises the operation of the inverter.
The main blocks are the DC-DC input converter (called “booster”) and
the DC-AC output inverter. Both, work at a high switch-over frequency,
and so are small and relatively light.
This inverter is equipped with a high frequency transformer, in other
words with galvanic isolation of the primary (DC side) from the seconda-
ry (AC side), while maintaining very high performance in terms of output
and energy export. This type of circuit allows for the grounding of the
inputs, both positive and negative, where required by the solar panel type
used or by the rules of the country of installation.
The inverter is equipped with a single input converter with maximum po-
wer point tracking (MPPT) to which it is possible to connect two strings
of photovoltaic panels.
Thanks to the high efficiency and the large heat dissipation system, a
maximum power operation is guaranteed in a wide range of the ambient
temperature without the use of external cooling fans.
The inverter is controlled by two independent DSPs (Digital Signal Pro-
cessors) and a central microprocessor.
The connection to the power grid is thus kept under control by two inde-
pendent monitors, in full compliance with the electric field norms both for
power supply to the systems as well as security.
The inverter is already equipped with all the protections necessary for
safe operation and compliance with the norms.
The operating system performs the operation of communicating with the
relevant components to carry out data analysis.
All this guarantees optimal operation of the entire unit and high
efficiency
in all insolation and load conditions, always in full compliance with the
relevant directives, standards and provisions.
