SmartgridOne Improvements

System & Usability Improvements

• Rule-based battery cost optimization
  Cost optimization can now be configured using fixed user-defined rules, giving installers and users more control over battery behavior.
• Clearer scheduler explanations
  The scheduler now reports the most important constraint and explanation per device category, making it easier to understand controller decisions in the app.
• Grid setpoint control through External Signals
  External signals can now control a target grid setpoint instead of individual device setpoints.
• Support for quarter-hour grid limits
  Added support for quarter-hour based grid limits such as Belgian “contractueel vermogen”.
• Support for peak shaving relay cascades
  Added a dedicated local control mode for relay-based peak shaving cascades.
• New language support
  Added Czech and Slovak translations to the commissioning interface.
• Scheduler performance improvements
  Frequently used scheduler code has been optimized, with speed improvements of up to 50% in some cases.
• Improved German Paragraph 14a implementation
  Enhanced support for the German Paragraph 14a energy management requirements.
• Peak shaving configuration down to 0.1 kW
  Peak shaving limits can now be configured with much finer precision.

Device & Driver Enhancements

• Dyness DH100F hybrid inverter: AC setpoints and PV production limits are now handled separately for more reliable control.
• GoodWe ESS driver: Improved support for the GoodWe ES G2 models.
• Sungrow Hybrid inverters: Improved status readouts for clearer inverter information.
• Solis inverters: Improved validation and handling of power setpoint percentages.
• Growatt VPP: Improved the Growatt VPP driver and onboarding behavior.
• SMA DataManager: Added filtering of outlier measurements for more stable readings.
• Eniris Generic Modbus: Added registers 309 and 416 to the generic Modbus protocol.
• GoodWe ESS: Added support for reading maximum charge and discharge current values.
• Omnipower batteries: Added maximum charge and discharge current registers.
• Deye SUN 3P: Added warnings when outdated inverter firmware is detected.
• Solinteg inverter integration: Added support for additional inverter models.
• AlphaESS G2H30: Added onboarding questions to determine whether PV is connected.
• Hybrid inverter groups: Added correct command destinations for hybrid inverter groups.
• Battery SOC reporting: The controller now directly reports the total site state of charge, improving app accuracy.
• Relay-controlled loads: Relay timing can now be reduced all the way to zero for highly responsive control.
• SMPLEnergie external signals: Added support for SMPLEnergie and improved external signal error handling.
• Sunwaytech Hybrid inverters: Refactored the integration for improved maintainability and consistency.
• Eniris Device MQTT external signal: Refactored the MQTT external signal driver for better maintainability.
• Elecnova ECOE233LS: Added support for multiple frequency scale factors.
• SAJ AS1 & H1: Refactored battery command handling for improved clarity and consistency.
• Faster and more stable control response: Added a new state estimator as an alternative to the settling check. This enables much faster control reactions while maintaining stability.
• Automatic setpoint correction: The bias compensator can now automatically compensate for differences between requested setpoints and actual measured device behavior.
• Smarter battery derating: The controller now automatically detects when batteries are unable to fully execute requested setpoints and dynamically adapts their limits.
• Better low-power battery coordination: At low power levels, the controller can now distribute energy more intelligently across multiple batteries, even putting some batteries to sleep to improve efficiency.
• More accurate battery scheduling: Historic battery behavior is now analyzed to better estimate realistic charge and discharge capabilities at different battery states of charge.
• More accurate energy calculations: Improved the calculation method for energy deltas to provide more accurate total energy readings.
• Improved low-price PV battery optimization: Battery cost optimization with PV production at very low electricity prices has been significantly improved.
• Controller health monitoring: Added scheduler jobs to monitor controller health automatically.
• Improved battery scheduling near SOC limits: Prevents sudden increases in charge or discharge limits when batteries are close to minimum or maximum state of charge.
• Improved democratic battery distribution: The democratic distribution algorithm can now run multiple times on the same battery to improve force charging behavior for nearly empty batteries.

Stability Improvements

• Poweroad CBMS: Fixed automatic contactor closing behavior.
• Zendure integration: Corrected power value handling.
