This guide explains how to configure an SMA system with Datamanager, for PV curtailment by an Octave battery or Octave Edgebox over Modbus TCP/IP.

There are two options:

  1. You assign Octave to configure the SMA system remotely.
  2. You configure the SMA system yourself on the local webinterface of the datamanager.

In both cases, you need to communicate the serial number of the SMA Datamanager (or inverter with datamanager), and injection tariff formula to Octave to get the system operational.

1. Assign Octave to configure the SMA system remotely

In this option, Octave will access the local web interface of the datamanager remotely via its battery system or Edgebox controller.

In this way, Octave can configure the datamanager remotely, without the need to go physically on site.

  1. Provide the Serial number of the SMA datamanager or the SMA inverter with integrated datamanager to Octave

    e.g. 3016690215

  2. Provide Octave with administrator login credentials for the local web interface of that datamanager:

  3. Octave will configure the system and enable the modbus TCP/IP server on the SMA datamanager.

  4. Provide the injection tariff formula to Octave for optimal PV curtailment, tailored to the customer’s tariff

2. Configure the SMA system yourself — over Modbus TCP/IP

To configure the SMA system for PV curtailment control by an Octave battery or Octave Edgebox over modbus TCP/IP, perform the following steps:

The interface is slightly different if there is a Separate Datamanager device, vs when the datamanager is integrated into an SMA inverter.
