Sunny Boy
Smart Energy 5.0 / 6.0 / 8.0 / 9.9

Version 3.17.xx.R (November 2026)

• ennexOS: Greater Flexibility in System Configuration
  All products based on the ennexOS platform can now be configured as a System Manager. This includes, for example, Sunny Tripower Hybrid X, Sunny Tripower X, Sunny Boy Smart Energy, and SMA eCharger.
  This allows the System Manager to be selected more flexibly according to the specific system design.
• New Integrated Energy Management for Optimized Energy Use
  The new firmware introduces new energy management functions based on the ennexOS platform.
  • Energy Planner (Manual)
    The Energy Planner, previously available under the name "Scheduler," is enabled by default and optimizes solar self-consumption around the clock. In addition, plant owners can:
    • Define time-dependent limits to reduce peak loads.
    • Manually schedule battery charging and discharging behavior.
    The names of the individual operating modes have been revised to make their functions easier to understand.
  • Energy Maximizer (Automatic)
    The Energy Maximizer controls the energy system fully automatically and intelligently with the goal of reducing electricity costs for plant owners. It considers factors such as:
    • PV generation forecasts
    • Consumption forecasts
    • Dynamic electricity tariffs
    Based on this information, the Energy Maximizer optimizes the use, storage, and procurement of energy.
• Control of Energy Consumption and Energy Generation via EEBUS
  The EEBUS use cases LPC and LPP can now be implemented through an EEBUS control box and the System Manager:
  • LPC (Limitation of Power Consumption): Limitation of energy consumption from the grid
  • LPP (Limitation of Power Production): Limitation of energy generation
  This enables targeted limitation of both energy consumption and energy production via EEBUS, for example to comply with the requirements of §14a of the German Energy Industry Act (EnWG).
• More Robust Modbus Communication
  The overall robustness of Modbus communication has been improved.
  In SCADA systems, parameters can now be transmitted at high frequency even if their values do not change with every transmission. If a value remains unchanged, no additional event is logged.
  In addition, the Modbus server profile has been standardized and is intended to be used for all new products. For existing applications, a compatibility server profile remains available via the Data Manager.
• Faster and Centralized Diagnostics
  In systems with devices based on the ennexOS platform, diagnostic files from subordinate devices can now be retrieved centrally through the System Manager.
  This simplifies analysis of the entire system, as diagnostic files no longer need to be retrieved separately from each individual device.
• Compatibility with SMA Storage M
  The Sunny Boy Smart Energy 3.6 to 9.9 is now compatible with the SMA Storage M with capacity ranging from 12.3 kWh (3 modules) to 28.7 kWh (7 modules).
• Certification for Spain
  The Sunny Boy Smart Energy 8.0 and 9.9 is now as well certified for the spanish market.
• Implementation of new grid codes
  For SBSExx-50: Great Britain and Poland
  For SBSExx-US-50: Puerto Rico
• Bugfixes / Improvements
  Includes various stability improvements and fixes known issues to ensure reliable system performance.
• Closed vulnerabilities
  CVE-2025-67735, CVE-2025-14524, CVE-2025-68161, CVE-2026-3805, CVE-2025-68471, CVE-2026-3783, CVE-2025-67735, CVE-2025-67735, CVE-2026-3784
• Please also refer to the lists of previous firmware releases below.
• Please note that as a result of the update, stand‑alone inverters that were previously configured as subordinate devices can no longer directly connect to Sunny Portal powered by ennexOS. Affected inverters must be reset and then configured again as a System Manager.
• Minimum version to update to 03.17.xx.R is 03.12.xx.R or higher.
  If the device has a lower version, enable automatic updates or use the "Check for update and install it" function via generic parameter section of the device.

Version 03.16.xx.R (April 2026)

• Improved behavior during grid anomalies
  During grid anomalies (e.g. overvoltage or overfrequency), in which the inverter normally needs to shut down, it is now possible to charge the battery with PV energy to avoid losses and improve overall performance.
• Optimized utilization of all batteries in the system during backup operation
  Batteries are balanced to maintain the same SoC during backup operation mode and can therefore contribute energy to the household.
• Battery Commissioning Test
  With Battery Installation Mode it is possible to charge and discharge the connected battery as a functional test during installation.
• Charging / discharging to a defined SoC level
  Manually bringing a battery module manually to a defined SoC level is now possible with this feature. This is mostly needed if a battery module from BYD or Pylontech is added to the system or replaced.
  (With the SMA Home Storage, this is not required as we have the automated module balancing within the firmware.)
• Easier and automatic configuration of sub-devices during commissioning via the System Manager
  Automatic setting of country codes, for example for sub-devices based on System Manager configurations; decreasing commissioning time.
• More detailed information about the status of the device
  Within the status widget of each device the current status is now displayed, e.g. “Backup“ if the device is in backup operation.
• Import and export of favorites for parameters or instantaneous values
  It is now possible to import or export selected parameters / instantaneous values as favorites to provide a clear overview at any time about the most important ones.
• Country codes that are outdated are now marked as “Obsolete”
• Support for the BattVO regulation
  Parameters of all attached batteries are available via the inverter’s user interface. Therefore, you have to select the device and navigate to Monitoring / Diagnosis / Battery data.
• Compliance with requirements of §14a EnWG (Energiewirtschaftsgesetz)
  The digital input of the SBSE can now be used to reduce the charging of the battery from the grid to be in conformity with §14a EnWG. If configured as a System Manager this signal can be forwarded to other batteries in the system.
• Bug fixing / Improvements
  This update includes various stability improvements and fixes to known issues to ensure more reliable system performance.
• Closed vulnerabilities
  CVE-2025-58057
• Minimum version to update to 03.16.xx.R is 03.12.xx.R or higher
  If the device has a lower version, please contact Service.
