The DC connections are used for connecting the PV module
string(s) to the solar inverter.
The integrated DC isolating switch can separate the solar inverter
from the DC voltage of the PV modules.
The maximum permissible input current is 29 A for each DC con-
nection.
Connection type: Multi-contact MC4 plug, paired plug (DC+) and
socket (DC-)

5.5.3 AC connection
The AC connection is used for connecting the solar inverter to the
grid.
The connection is made using a triple-core cable (L, N, PE).
Connection type: Wieland RST25i3s, plug supplied in the scope of
delivery.
5.5.4 RS485 interface (EIA485)
The solar inverter has two RS485 interfaces to which a PC or a
monitoring system can be connected.
The RS485 interfaces are internally wired 1:1. This means that both
RS485 interfaces can be used as an input or an output.
If multiple solar inverters are connected together, each solar
inverter must have a unique ID (identification number). Monitoring
systems require the ID to recognize each solar inverter in a PV
system.
The last solar inverter must have an RS485 termination resistor
connected, which can be ordered from Delta (see
“16.1 Order num-
bers”, p. 82).
The ID can be configured during commissioning (see
“8 Commis-
sioning”, p. 34
) and can be changed at any time during operation
(see
“10.6 RS485 (EIA485) Settings”, p. 54
).
Connection type: 2 x RJ45
