Sunny Tripower X 25 12 / 15 / 20 / 25

Version 03.17.xx.R (November 2026)

Firmware features & improvements:

• 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.
• Implementation of new grid codes
  for Austria, Great Britain, Switzerland and Saudi Arabia
  for STP X 30-US: 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)

Firmware features & improvements:

• Introduction of a new parameter for residential acoustic optimization
  See operating manual Residential Optimization
• Simplified and automatic configuration of subordinate devices during commissioning via the System Manager
  Subordinate devices now automatically receive settings such as country codes based on configurations within the System Manager and decreasing commissioning time
• More detailed information about the status of the device
  The status widget now shows the current operating state
• Import and export of favorite parameters or instantaneous values
  Users can now import or export selected parameters/instantaneous values as favorites to have a clear overview about the most important ones anytime
• Outdated country codes are now marked as “Obsolete”
• Implementation of new grid codes
  for Czechia and Poland
• Bugfixes / Improvements
  Includes various stability improvements and fixes known issues to ensure reliable system performance
• Closed vulnerabilities
  CVE-2025-58057
• 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 03.16.xx.R is 03.12.xx.R or higher
  If the device has a lower version, please contact Service.
