Victron and ABB/Fimer PV Inverter Monitoring Setup

Key Takeaways

• Victron systems can control ABB/Fimer PV inverters for functions like Zero feed-in.
• Commissioning can be done via a mobile app or the inverter's web interface.
• Always ensure AC power is off when initially accessing the inverter's web interface.
• Administrative access requires a specific password obtained from your distributor.
• If you are unsure about any electrical steps, stop and consult a qualified technician.

How do I set up Victron to monitor and control my ABB/Fimer PV inverter?

Setting up your Victron system to monitor and control an ABB/Fimer PV inverter primarily involves configuring the inverter for communication and power control, such as Zero feed-in. The most common first step is to access the inverter's configuration interface, either through a dedicated app or its webserver.

Diagnosis and Setup Steps

This section outlines the steps to configure your ABB/Fimer PV inverter for integration with a Victron system.

1. Identify your inverter model:

• • Check: Verify the exact model number of your ABB/Fimer PV inverter.
  • Meaning: This ensures compatibility with the Victron system. Supported models include single-phase UNO-DM-PLUS/PLUS-Q, three-phase TRIO-TM-50/60, high-power PVS-100/120, and multi-power PVS-10/12.5/15/20/30/33/50/60.
  • Action: Proceed if your model is listed as known to work.

2. Choose a commissioning method:

• • Check: Decide whether to use a mobile app or the inverter's web interface.
  • Meaning: Commissioning the inverter can be done in two ways. You can use the 'INSTALLER FOR SOLAR INVERTERS' app, available on Apple and Android, or you can log in to the webserver.
  • Action: Select the method you are most comfortable with.

3. Prepare for webserver access (if chosen):

• • Check: Ensure AC power to the inverter is off, but DC power is on.
  • Meaning: To access the inverter's web user interface, you must switch on DC power to the inverter while leaving AC off. This ensures a safe configuration environment.
  • Action: Isolate the AC supply to the inverter before proceeding.

4. Connect to the inverter's web interface:

• • Check: Use a web browser to connect to the inverter's local IP address.
  • Meaning: This allows you to access the configuration settings directly from a computer or mobile device.
  • Action: Enter the inverter's IP address into your browser's address bar.

5. Obtain administrative access:

• • Check: The inverter interface will likely require a password for full configuration access.
  • Meaning: You need the admin plus password for administrative access. This password must be obtained from your distributor.
  • Action: Enter the correct password to proceed with configuration.

6. Configure for Victron control (e.g., Zero feed-in):

• • Check: Look for settings related to external power control or grid interaction.
  • Meaning: Allow the Victron system to control the output power, specifically for Zero feed-in. This uses the same mechanism used for Fronius PV inverters.
  • Action: Enable the necessary settings to allow the Victron system to manage the inverter's power output.

Setup Task and Resolution Table

This table outlines common setup tasks and their corresponding requirements or actions when integrating an ABB/Fimer PV inverter with a Victron system.

Integrating ABB/Fimer Inverters with Victron Systems

Integrating your ABB/Fimer PV inverter with a Victron energy system allows for advanced monitoring and control, such as managing grid export. The core functionality revolves around the Victron system's ability to control the inverter's power output. This is particularly useful for implementing Zero feed-in, where the PV production is matched to local consumption, preventing excess energy from being sent to the grid.

The commissioning process for ABB/Fimer inverters offers flexibility. You can use a dedicated mobile application, the 'INSTALLER FOR SOLAR INVERTERS' app, which is available on both Apple and Android platforms. This app provides a user-friendly interface for initial setup and configuration. Alternatively, for more detailed adjustments or if a mobile device is not preferred, you can access the inverter's webserver directly through a web browser.

When accessing the webserver, it is crucial to follow the correct power-up sequence: switch on DC power to the inverter but leave AC off. This ensures that the inverter is powered for configuration without being connected to the grid, providing a safer environment for initial setup. Administrative access to these settings requires a specific password, known as the admin plus password, which must be obtained from your distributor. This security measure helps prevent unauthorized changes to your system's operation.

Safety: Working with PV Inverters

Working with PV inverters involves high voltages and currents that can be dangerous. Always prioritize safety.

• Isolate Power: Before performing any physical work on the inverter or its connections, ensure both the AC and DC power supplies are completely isolated. This means turning off all relevant circuit breakers and disconnect switches.
• Verify De-energization: Use a multimeter to confirm that all circuits are de-energized before touching any terminals or internal components.
• Lockout/Tagout: Implement lockout/tagout procedures to prevent accidental re-energization of the system while you are working.
• Qualified Personnel: Electrical work should only be performed by qualified and experienced personnel. If you are unsure about any step, do not proceed.
• Insulated Tools: Always use properly insulated tools to prevent accidental shorts or shocks.

When to call a technician instead

While this guide provides steps for setting up your ABB/Fimer inverter with a Victron system, there are situations where professional assistance is necessary. You should call a qualified solar technician if:

• You are unable to obtain the admin plus password from your distributor.
• You encounter persistent communication errors between the Victron system and the ABB/Fimer inverter that cannot be resolved through basic troubleshooting.
• You are uncomfortable performing any of the electrical isolation or configuration steps.
• Your inverter is displaying fault codes not covered by this setup guide, or if the system is not behaving as expected after following all instructions.
• Any physical damage is observed on the inverter or its wiring.
• You are concerned about voiding your warranty by attempting complex configurations without professional guidance.
