Input Connection To Pv Generator (Dc Side) - ABB PVS-175-TL-SX2 Product Manual

I
nput connection to PV generator (DC side)
Comply with the maximum input current relating to the quick-fit connectors as indicated in the
technical data.
Polarity inversion can cause serious damage. Check polarity before connecting each string!
When the photovoltaic panels are exposed to sunlight they provide continuous DC voltage
to the inverter. To avoid risks of electrical shock, all wiring operations must be carried out
with the DC disconnect switches (internal

Caution! The inverters referred to in this document are TRANSFORMERLESS. This type re-
quires the use of insulated photovoltaic panels (IEC61730 Class A Rating) and the need to
keep the photovoltaic generator floating with respect to ground: no terminal of the generator
must be connected to ground.

After having carried out preliminary checks and therefore having verified
that there are no problems in the photovoltaic system, you may connect
the inputs to the inverter.

For the string connections it is necessary to use the quick fit connectors
located on the left side of the wiring box

According to IEC 62548 (Photovoltaic (PV) arrays – Design
requirements), connectors mated together in a PV system
shall be of the same type from the same manufacturer, i.e. a
plug from one manufacturer and a socket from another manu-
facturer or vice versa shall not be used to make a connection.
Using mating parts of different type or brand than those spe-
cified above could cause serious damage to the unit and will
lead to the invalidation of the warranty.

The input connectors are divided into 12 MPPTs (one MPPTs for each
input channel) consisting of 2 pairs of quick fit connectors.
