2. Installer setup (off-site)

Please complete the installer setup before heading on site.

2.1 Create an installer account

When you open the MyDeltaSolar App for the first time, you should see the Login screen. Under

the email field, please type “installer” and click the blue sign-in button to begin the installer

account registration.

Next you should see the installer account registration page. Complete all the fields, and choose

your limit for number of inverters commissioned per day.

Note: the password must contain at least 1 number (0-9) and 1 special character (%@,./).

3. Installer grid-connect (on-site) 4

A pop-up message will appear, saying to wait for approval. This approval needs to be made by

Delta – once you see this message, please contact Delta Energy Systems (Australia) either by email:

solarsupport@deltaww.com or via the customer hotline 1300 335 823.

After approval has been granted, the installer account may be logged into freely and the RPI Flex

inverter can now be connected to the grid.

3. Installer grid-connect (on-site)

If you are not currently on the Login screen, close the app and reopen it. Closing and reopening the

app at any time will log out the current user and bring up the Login screen.

To sign into your installer account created in step 2 above, please enter in the email address used

and add “/installer” at the end of the email address. Next, enter in the password chosen for your

account and then click the blue sign-in button. See the image below for reference.

3. Installer grid-connect (on-site) 5

3.1 Connecting your mobile device to the inverter

After you have logged in for the first time, you should be prompted to connect to the inverter

through Wi-Fi. In your phone’s settings, choose the RPI Flex inverter’s local network as shown

below – the name of the network will be Delta-<RPI Flex Serial Number>.

When prompted to enter the network password, the default password for the local network is

DELTASOL (case-sensitive).

3.2 Initial setting and connecting to the grid

Once you have connected to the inverter through Wi-Fi, head back to the MyDeltaSolar app – you

will then be taken to the Initial Setting page.

Choose Australia as the country, and the inverter ID can be changed as necessary if the PVI system

consists of multiple RPI Flex inverters. Click the blue set button, and a success message will popup.

4. End-user cloud connection 6

After completing the initial setting, the RPI Flex inverter will begin to connect to the grid. You

should see the inverter status as countdown, and shortly afterwards change to on grid with the

production ramping-up slowly.

4. End-user cloud connection

In order to monitor the RPI Flex’s production data on the cloud, an end user account must be

created, then the inverter linked to the cloud via the MyDeltaSolar app. If the end user does not

want to use cloud monitoring, the “no” bubble should be selected during end user account

registration in Section 4.1. Should this be the case, the RPI Flex production data can only be

monitored via a Wi-Fi point-to-point connection between the mobile device and the inverter.

4.1 End-user account registration

If you are not currently on the Login screen, close the app and reopen it. Closing and reopening the

app at any time will log out the current user and bring up the Login screen.

To create an end user account, click on Create account.

4. End-user cloud connection 7

You will now see the end user register page – please fill in all of the fields, and note that the

password must contain at least 1 number (0-9) and 1 special character (%@,./).

To complete the registration, click the blue register button at the bottom of the screen.

4.2 Load initial setting & cloud service terms and conditions

If the mobile device is already connected to the RPI Flex inverter through Wi-Fi, the Initial Setting

page will appear and the three fields (shown below) will be filled automatically. If the mobile device

is not connected to the inverter, you will be prompted to connect. Refer to Section 3.1 for details

on how to connect via Wi-Fi. Once completed, click the blue set button.

4. End-user cloud connection 8

Next you will see the MyDeltaSolar cloud service terms and conditions page. Please read through

these terms and conditions – if you agree, tick the checkbox before clicking the blue OK button.

4.3 Change inverter network password

For security reasons, you will need to change the network password of the RPI Flex inverter from

the default password. You have two options:

Set the inverter’s password to be the same as the end user account (see below on left)

Set the new password to one of your own choice (see below on right)

Once the password fields are filled, you may click the blue set button.

…

4. End-user cloud connection 9

4.4 Connecting the inverter to a local network

This step involves connecting the RPI Flex inverter to your local network so that production data

can be uploaded to the cloud.

Click the blue scan button, and wait till the scan for local networks is complete.

You should now see a list of networks – click the bubble corresponding to the network you wish to

connect your inverter to.

When prompted, enter in the password for the network, and click the blue connect button.

If you cannot see your network listed after scanning, then the signal strength of your

network may not be strong enough. You can try scanning again by clicking the scan

button, however you may need to improve the signal strength of the network with a

repeater or access point.

You should see a connect error, or a connect success message after approximately 30

seconds. The connect success message means your inverter is connected to the cloud,

otherwise the connect error message means the connection to the cloud was not

successful.
