DC
Combined solar module strings with total cur-
rent greater than 28 A (l
dcmax
).
Module array settings:
PV 1: ON
PV 2: OFF
PV 1 + PV 2 (connected in parallel):
ON
IMPORTANT!
The maximum current load of a single
terminal is 28 A. PV‑connection strings
with a total current of more than 28 A
must be split between both PV inputs
upstream of the terminals (I
SC max
≤ 60 A). The plug connection for split-
ting the total current must be suffi-
ciently dimensioned, suitable and cor-
rectly installed. Splitting the current
by bridging from PV 1 to PV 2 at the
terminal is not permitted.
PV 1 less than or equal to 40 A (I

PV 2 less than or equal to 20 A (I
