What to do before you go to site

Ensuring a successful installation begins long before arriving on site. The following guide outlines the essential steps and checks required to prepare your Smart Grid Device (SGD/Droplet) and supporting systems for deployment.

1. Verify All Required Hardware

SGD (Droplet) Components

Before leaving for site, confirm that the SGD (Droplet) package includes all critical parts:

  • SGD (Droplet) unit

  • Power supply

  • Antennas

  • SIM card

  • Any other required mounting or connection accessories

Additional Accessories (Optional-based on your requirement)

Check that all supporting accessories are present:

  • Ethernet cable (needed for the internet connection)

  • RS485 cable

  • Additional connectors, if required

It is strongly recommended to bring extra accessories and, where possible, carry a spare SGD (Droplet) to avoid project delays in case of unexpected hardware issues.This will also makes you avoid long trip when connecting remote sites.

2. Complete Required Training and Accreditation

You’ll need to sign up for the academy using this form and then complete the applicable accreditation course.
Installer Accreditation

SwitchDin Accreditation

Ensure you have completed the official SwitchDin accreditation course:

 

SwitchDin Horizon Power Accreditation Course

Complete the Horizon Power training module:

 

Once you complete one of the accreditation courses above, you will gain access to the SwitchDin Storm Cloud app as an installer. This access is required to complete commissioning and installation.

3. Confirm Access to Stormcloud

Verify that you are accredited and signed in to the SwitchDin Stormcloud platform.
This ensures you can add devices, configure systems, and troubleshoot on site without delays.

4. Firmware & Configuration Preparation

Update Device Firmware

  • Ensure the SGD (Droplet) has the latest firmware by connecting it to the internet and leaving it connected for 24 hours.

Check Inverter Compatibility

Verify that the specific inverter model is supported by Horizon Power Smart Connect Solar:

 

Ensure you understand how the SGD connects to the inverter—this will be either via RS485 serial communication or a TCP network connection.

  • If using RS485:
    Confirm the correct inverter pins for the RS485 connection before going to site. Contact the OEM to verify how the inverter interfaces with external devices such as the SGD.

  • If using TCP:
    Make sure you know how to connect both the SGD and the inverter to the same network so they can communicate.
    Also ensure you understand how to enable TCP port 502 in the inverter settings.

     

  • If your system size is above 30 KW read this article

  • Private or Secure Networks

    If the installation site uses a private or secure network, please let us know ahead of the scheduled installation date.
    This allows us to coordinate with the site's IT team to review any network requirements or potential restrictions.

    Be prepared to liaise with the IT department if needed, especially if specific routing or firewall configurations are required to bring the device online. If the site uses a secured network environment, please help facilitate a meeting or email exchange with the IT team to ensure a smooth setup.

5. Perform Bench Testing (Recommended)

Before heading to site, carry out a bench test at home or in the office if possible.
This may include:

  • Powering up SGD

  • Connecting the SGD to your home or office LAN.

  • Making sure the SGD is online and updated.

  • Confirming communication between the inverter and the SGD (if possible)

Bench testing helps identify issues early, saving significant time on site.

6. Schedule Site Arrival During Daylight

Solar inverters require active solar generation for proper testing.
Aim to arrive during daylight hours to ensure all solar-related functionality can be tested.

7. Prepare Key Contact Information

Carry the contact details for:

  • Site manager or site owner

  • Network administrator (if IT support is required for restricted network)

  • SwitchDin Support Team (support@switchdin.com and phone number is +61 2 4786 0426)
    (In case troubleshooting or remote assistance is needed)

Conclusion

Proper preparation is essential for a smooth SGD (Droplet) installation. By verifying hardware, completing training, confirming system access, performing bench tests, and ensuring communication readiness, you significantly reduce the risk of delays or issues on site. Following this guide ensures you are fully equipped and ready for a successful deployment.
