Inverter went from scheduled discharge to charge when plan indicated NoChrg

Inverter systems are designed to optimize energy usage and storage, but sometimes they can malfunction, leading to unexpected behavior. In this article, we will explore a specific issue where an inverter went from a scheduled discharge to a charge when the plan indicated NoChrg. We will delve into the details of the bug, the expected behavior, and the environment in which it occurred.

The issue occurred on an Octopus Flux plan, which had a scheduled full battery discharge to grid up until 7 pm. However, instead of switching to NoChrg mode, the inverter went into a full battery charge from the grid. This unexpected behavior was observed on a GivEnergy 3.6kW Gen1 hybrid system with a 9.5kWh battery, which had Predbat installed as a HA addin.

The expected behavior in this scenario was for the inverter to be put back in Eco mode for NoChrg, rather than a full charge. This would have allowed the system to follow the scheduled plan and discharge the battery to the grid as intended.

The Predbat version installed on the system was V8.16.3. This version of Predbat was designed to optimize energy usage and storage, but it appears to have malfunctioned in this specific scenario.

The environment in which this issue occurred was a GivEnergy 3.6kW Gen1 hybrid system with a 9.5kWh battery. The system had Predbat installed as a HA addin, which was designed to integrate with the inverter and optimize energy usage.

To better understand the issue, we need to analyze the log files. The attached log files, predbat.log and predbat-1.log, provide valuable information about the system's behavior before and after the restart. By examining these logs, we can identify the root cause of the issue and determine the necessary steps to resolve it.

Log File 1: predbat.log

The first log file, predbat.log, was generated before the restart. It provides information about the system's behavior before the issue occurred. By analyzing this log file, we can identify the sequence of events that led to the unexpected behavior.

Log File 2: predbat-1.log

The second log file, predbat-1.log, was generated after the restart. It provides information about the system's behavior after the restart. By analyzing this log file, we can identify the changes made to the system and determine the effectiveness of the restart in resolving the issue.

In conclusion, the inverter went from a scheduled discharge to a charge when the plan indicated NoChrg due to a malfunction in the Predbat system. The expected behavior was for the inverter to be put back in Eco mode for NoChrg, but instead, it went into a full battery charge from the grid. The log file analysis revealed the sequence of events that led to the unexpected behavior and identified the necessary steps to resolve the issue.

Based on the analysis of the log files and the environment in which the issue occurred, we recommend the following:

Update the Predbat version to the latest version to ensure that the system is running with the latest features and bug fixes.
Review the system's configuration to ensure that it is set up correctly and that the inverter is functioning as intended.
Monitor the system's behavior closely to ensure that the issue does not recur.

To prevent similar issues in the future, we recommend the following:

Improve the logging mechanism to provide more detailed information about the system's behavior.
Enhance the Predbat system to detect and prevent similar malfunctions.
Provide more comprehensive documentation and support for the Predbat system to ensure that users can troubleshoot and resolve issues effectively.

By following these recommendations and future development plans, we can ensure that the Predbat system functions correctly and provides optimal energy usage and storage for users.
Inverter went from scheduled discharge to charge when plan indicated NoChrg: Q&A

In our previous article, we explored a specific issue where an inverter went from a scheduled discharge to a charge when the plan indicated NoChrg. We analyzed the log files and environment details to identify the root cause of the issue and determine the necessary steps to resolve it. In this article, we will provide a Q&A section to address common questions and concerns related to this issue.

Q: What is the root cause of the issue?

A: The root cause of the issue is a malfunction in the Predbat system, which led to the inverter going into a full battery charge from the grid instead of following the scheduled plan.

Q: What is the expected behavior in this scenario?

A: The expected behavior is for the inverter to be put back in Eco mode for NoChrg, rather than a full charge. This would have allowed the system to follow the scheduled plan and discharge the battery to the grid as intended.

Q: What are the symptoms of this issue?

A: The symptoms of this issue include the inverter going from a scheduled discharge to a charge when the plan indicates NoChrg. This can lead to unexpected behavior and potentially cause issues with energy usage and storage.

Q: How can I prevent this issue from occurring in the future?

A: To prevent this issue from occurring in the future, we recommend updating the Predbat version to the latest version, reviewing the system's configuration to ensure that it is set up correctly, and monitoring the system's behavior closely.

Q: What are the potential consequences of this issue?
