What to Look For:

The Signature Solar Gateway displays a "Battery Version Not Supported" error in the monitoring app and/or on the gateway's display panel. The system may not charge/discharge the battery, report incorrect state of charge (SOC), or fail to provide backup power during grid outages.

Possible Causes:

Outdated Gateway firmware lacking support for the connected battery's firmware version.
Incompatible battery firmware requiring a Gateway firmware update.
Corrupted firmware on the Gateway due to interrupted updates or power fluctuations.
Intermittent network connectivity preventing the Gateway from verifying battery compatibility with the cloud server.
Incorrect battery settings configured within the Gateway's software.
An API communication error between the Gateway and the battery BMS.

Technical Recommendation:

Access the Gateway's advanced settings menu (if available via a specific key combination or through Signature Solar support) to view real-time CAN bus communication status and identify any communication errors with the battery BMS.

Critical Safety Precautions:

Never attempt to open or modify the internal components of the Gateway or battery. Unauthorized modifications can void the warranty and potentially create hazardous conditions. Ensure the DC disconnect is OFF before performing any inspection or maintenance to comply with NEC rapid shutdown requirements. Protect your account credentials to prevent unauthorized system access.

Recommended Action:

1

Verify network connectivity of the Gateway via the monitoring app. Ensure a stable Wi-Fi or ethernet connection.
2

Check for Gateway firmware updates within the monitoring app settings. If available, initiate the update process and ensure uninterrupted power supply during the update.
3

Confirm the battery model and version are correctly identified within the Gateway's configuration settings in the app.
4

Cycle the Gateway power by disconnecting and reconnecting the DC disconnect switch, then power cycle the gateway via the breaker. Allow the system to reboot and re-establish cloud connection.
5

Review the Gateway's error logs within the app for detailed information regarding the battery version incompatibility. Note any timestamped events.
6

If the problem persists, contact Signature Solar support and provide the Gateway's serial number, battery model, and the error logs.
7

Check the monitoring app for any alerts related to API connectivity issues. Address network or account problems that might prevent data synchronization.

How It Works:

The Gateway acts as a communication bridge between the solar inverter, battery management system (BMS), and the cloud monitoring platform. It validates battery firmware versions against a compatibility matrix stored locally or in the cloud. Incompatible versions can result in communication failures over CAN bus or Modbus, preventing accurate data exchange and proper system operation. Failure to synchronize data with the cloud can also cause misreporting.

Preventative Care:

Regularly check for and install Gateway firmware updates through the monitoring app.
Monitor network connectivity to ensure consistent data synchronization with the cloud.
Periodically review system logs within the app for any errors or warnings related to battery communication.
Maintain a strong and unique password for your monitoring app account to prevent unauthorized access and configuration changes.
