6 Planning the Commissioning
Introduction

Planning the Commissioning
6.1
Introduction
Once the inverter has been installed and all electrical connec-
tions (to the grid, to the solar modules, communication) have
been set up, the inverter can be commissioned.
In order to allow you to plan commissioning on site, the various
commissioning methods are briefly described in this chapter.
6.2
Commissioning options
6.2.1 Delta Service Software (DSS)
The Delta Service Software is available for Windows PCs.
The PC is connected to the RS485 terminal block of the inverter.
You must commission each inverter individually.
You can use the DSS to set all parameters of the inverter.
The firmware of the inverter can be updated with this method.

6.2.2 MyDeltaSolar app with direct connection to
the inverter via Wi-Fi
The MyDeltaSolar app is available for mobile devices (smart-
phone, tablet) with iOS or Android.
The mobile device is connected directly to the inverter via Wi-Fi
(point-to-point connection). This requires the Wi-Fi module to be
installed on the inverter, which must be ordered separately.
Since this creates a point-to-point connection between the mobile
device and the inverter, you must commission each inverter indi-
vidually.
With the MyDeltaSolar app you can set all parameters of the
inverter.
The firmware of the inverter can be updated with this method.
6.2.3 MyDeltaSolar app with DC1 Data Collector
from Delta
The DC1 can connect to the inverter via RS485, Wi-Fi or Sub-
1G. These connection types can also be used in combination.
For details, refer to the manual of the DC1 data collector, in par-
ticular the number of inverters that can be connected to the DC1
via the respective connection variant.
When RS485 is used, the DC1 is connected to the RS485 termi-
nal block of one of the inverters in the RS485 series.
The Sub-1G antenna is included in the scope of delivery.
The Wi-Fi module must be ordered separately.
You can perform the following tasks on the inverters connected to
the DC1:
●
Commission all inverters at the same time.
●
Set all parameters of the inverters.
●
Update the inverter firmware.
