Released: May 2026

Previous release: v1.6.7.0

This is a major release. The headline feature is full remote firmware update support for both the controller and the cellular modem, plus a wide range of reliability, fault-handling, and user-interface improvements.

Important: When updating from an earlier version of controller firmware, the modem firmware must also be updated at the same time to remain compatible.

Important: because this release introduces remote updates, v2.0.0.0 must be installed on-site. Future controller updates can be delivered remotely over the cellular or wifi connection.

Remote firmware updates

• Controller and modem firmware can now be updated and reverted both locally and remotely.

Reliability and stability

• Automatic recovery from low-level communication protocol errors
• Improved memory management to avoid unintended controller resets.
• More reliable cloud uplink under high bandwidth.

Settings and Control

• Added generator mode to be able to configure for generator connections on the input (charger) and the output (fixed export + regen)
• Added generator cooldown period where input current slowly ramps down after target SOC is reached

Faults and alerts

• Added latching time to faults triggering the Any Fault metric, to reduce alerting noise.
• Added a generator fault indicator for alerting in scenarios where a generator supplies intermittent input power based on gen signal.
• Fire-suppression activation uses latched value to stop the fans.
• Remove false positive "charger power loss" alerts when a charger is unplugged.
• The active faults list includes severity level.
