Overview of firmware versions
Systems with parallel operation with the utility grid
The system structure and system configuration (e.g. as battery-backup system) determine the firmware version that is required for commissioning the system.
System structure | SMA Energy System Home with increased self-consumption | SMA Energy System Home with increased self-consumption and battery backup | Battery-backup system |
|---|---|---|---|
Single system or single-cluster system | from 3.20.09.R | from 3.20.09.R | from 3.20.09.R |
Multicluster system with MC-Box-12.3-20 | Only with 1.04.00.R | Only with 1.04.00.R | Only with 1.04.00.R |
Multicluster system with MC-Box-12.3-20 and GRID-BOX-12.3-20 1) | Only with 1.04.00.R | Only with 1.04.00.R | Only with 1.04.00.R |
Off-grid system
The system structure and external energy source (e.g. generator) determine the firmware version that is required for commissioning the off-grid system.
System structure | Generator | Utility grid | Generator and utility grid |
|---|---|---|---|
Single system or single-cluster system | from 3.20.09.R | from 3.20.09.R | from 3.20.09.R2) |
Multicluster system with MC-Box-12.3-20 | from 3.20.09.R | from 3.20.09.R | - |
Multicluster system with MC-Box-12.3-20 and GRID-BOX-12.3-201) | - | - | from 3.20.09.R |
Multicluster system with MC-Box-6.3-11 or MC-Box-36.3-113) | from 3.20.09.R | - | - |
1) GRID-BOX-12.3-20 can only be used in countries where compliance with the European requirements for grid connection as set out in Commission Regulation (EU) 2016/631 for establishing a network code (known as RfG) is not required.
2) An external automatic transfer switching device is required.
3) Only suitable for off-grid systems.
