5.2.1.2 Version ≥275kW and all models
without insulation Transformer
For the models with Transformer, the
“ACBOX” area Figure 5-1(A) is divided in two
parts. The part containing the Transformer
“ACbox-Transformer” is separated from the
tower and contains the cover and the
dedicated cooling system with a thermostat
and five fans (Figure 5-9).

with power ≥275kW with Transformer)
All other parts are located in the bottom
area of “ACBOX-TL” represented in Figure
5-4.
The connection area of the DC cables from
the photovoltaic field is located on the left
side of the ”ACBOX-TL”. Positive inputs are
on the left side and negative inputs on the
right side (Figure 5-10). The correspondent
numeration of the "55kW MODULES" goes
from the first outermost (module 1) to the
last innermost (module 6). For the 165kW
and 220kW versions, 4 connection bars are
present. For the ≤110kW versions, 2
connection bars are present.
