opographic diagram of the equipment UNO-2.0/3.0-TL-OUTD
The diagram summarises the internal structure of the inverter.
The internal circuitry of the 2 and 3kW power levels is with double stage
conversion and therefore consists of:
- DC/DC input converter (booster)
- DC-AC output inverter
The DC-DC converter and the DC-AC inverter both work at a high switch-
ing frequency and are therefore small and relatively light.
The input converter is dedicated to a single string/array and is equipped
with a maximum power point tracking (MPPT) function.
This inverter version is of the transformerless type, that is without gal-
vanic insulation between the input and the output. This allows the conver-
sion efficiency to be increased further. The inverter is already equipped
with all the protections necessary for safe operation and compliance with
standards and regulations, even without the insulating transformer.
The connection to the power grid is therefore kept under control by two
independent processors, in full compliance with the electric field regula-
tions both for power supply to the systems as well as security.
The operating system carries out the task of communicating with its com-
ponents in order to carry out data analysis.
In doing all this, we guarantee optimal operation of the whole assembly
and a high performance in all sunlight conditions and always ensuring full
compliance with the relevant directives, standards and regulations.
