Available today, Multi RS firmware v1.29 improves system stability in three-phase systems with improved phase rotation detection, preventing random disconnects. The update also adds grid code support for Denmark and includes several fixes and improvements across RS products.

Key updates

• Improved phase rotation detection to reduce “Multi phase issue” disconnects in three-phase systems
• Added grid code support for Denmark (Multi RS)
• Fixed a communication issue with VE.Bus BMS v2 and VE.Bus BMS NG, ensuring the charger enters safe mode if the BMS is removed (applies to all RS products)

Other fixes and improvements applying to Multi RS and Inverter RS:

• Prevent inverter restart when phase assignment (L1/L2/L3) is changed in stand-alone mode.
• Added warning #77 “settings sync disabled” for mixed synchronisation configurations.
• Partial synchronisation of system configuration, including shared phase rotation settings.
