Device communication and system monitoring
5.7.6 Connection of a DC1 data collector from
Delta
You can use the DC1 data collector for, among other things:
● Commissioning the inverter (see “6. Planning the Commis-
sioning”, page 48 and “8. Commissioning”, page 92)
● Updating the rmware
● Connecting to the MyDeltaSolar Cloud or another monitor-
ing system
Follow the instructions in the DC1 manual to connect the inverter
to the DC1.
The inverter can be connected to the DC1 via RS485, Sub-1G or
Wi-Fi.
Connection via RS485
v
Observe the general instructions in section “5.7.5 Connection of
a data logger via RS485”, page 42.
The DC1 does not have an integrated RS485 termination resis-
tor. For this reason, refer to the information in Fig. 5.36, p. 43.
