DC1-100 Monitoring Gateway

 

DC1-100 Data Collector

The DC1-100 is a monitoring device which collects data from Delta solar inverters and P-Series power meters. This data is made available for access online via web browser at www.mydeltasolar.com.au for PC users and via MyDeltaSolar App available for Android and IOS for smartphone users. Smartphone users can also connect directly to the DC1 to access a local interface which can be used to comission and configure settings. Previously, all Delta RPI inverters would need to be connected to and comissioned separately. This device simplifies commissioning and maintenance of both existing and new Delta solar installations as the data and configuration settings of all inverters and meter can be accessed and configured via a single interface. For installers with many systems, fleet management is also available.

Data and settings can be accessed while the user is either,

  • On site – by connecting a phone directly to the DC1 wifi access point using the MyDeltaSolar app available for android and ios.
  • Via internet at www.mydeltasolar.com.au (if using a PC) or via the my-delta-solar app if using a smartphone.

The DC1 communicates with Delta solar inverters and power meters via RS-485 or wifi. If a compatible P-Series meter and inverter is installed, export limiting can be configured to comply with the soft limit requirements of AS/NZS 4777.1:2016, where inverters are power limited such that the amount of power being exported to the grid is limited to a value which is set by the user. An interface for a DRED device is also available on the DC1 which allows DRM signals to be applied if this is required by the local networks. See compatibility tab above to ensure that products have compatible firmware versions. Firmware upgrade instructions are in the manual available in the downloads tab, FW files are available for download in the downloads tab.

 

Physical Installation

DC1-100 Overview - Exploded Diagram

The physical connections and components of the DC1-100 are shown below. There is a DIN mounting clip on the back and the overall dimensions can be found in the manual available in the downloads tab above. The table provides an explanation of LED colours and flashing sequences.

Basic wiring - Example of Switchboard wiring diagram

The diagram below shows the DC1-100 connected to the P1E power meter via RS485. The meter is measuring power flowing through the incoming mains and providing this data to the DC1 which is power limiting the inverter in order to limit the amount of power exported to the grid. Please refer to the commissioning tab above to see how the installer would configure the DC1-100 and inverter using the app and make production and consumption data available to the customer online.

Application 1 - Example SLD for export limiting a single H5A

The installation below is an example of a RPI H5A with ~6.6kW of panels connected on a single phase property where export limiting is required. Please refer to the commissioning tab above to see how the installer would configure the DC1-100 and inverter using the app and make production and consumption data available to the customer online.

Application 2 - 2 x H5A inverters on a 2 phase installation with export limiting and phase interlocking

In many situations, it is required that no more than 5 kVA of unbalanced (or single phase) generation can be connected to the grid, otherwise current imbalance protection may be required. It is also required that if multiple single phase inverters are connected across different phases, if one inverter has a fault that causes it to stop working, the other inverter must also shut down. The diagram below shows how both of these requirements can be achieved on a 2 phase installation. A 5 kVA H5A is connected on each phase, a P3E meter with DC1 is installed at the connection point. see the comissioning tab above for a video on how the installer would use the MyDeltaSolar App and commission the system such that no more than 5kVA to be exported to the grid and enable the interlocking feature.

Comissioning

The video below shows how the installer would use the MyDeltaSolar app to configure the comission a single RPI H5A and export limit the system such that the DC1 will power limit the inverter so that power is not exported to the grid.

 

The phisical installation would be wired as shown in the Example "SLD for export limiting a single H5A" available in the "physical installation" tab above.

 

 

Compatibility

MyDeltaSolar App

  • The MyDeltaSolar app is constantly being updated and you should ensure that you upgrade to the latest version prior arriving on site.

Inverters

  • Flex HX/HXA - The minimum firmware versions for current features are listed in the table below

Power Meter

  • P1E- The 7-9th digit of the serial number must be at least 172 (i.e. 172, 173,174,175 and above would be acceptable) example serial number - PPM P1E-000O2S1720000W0
