Suitable PV Inverters
In an SMA Home Energy Solution with the Sunny Tripower Smart Energy, only the STPx.0-3SE-40 can feed the battery-backup system, no other PV inverters.
No three-phase PV inverters in single-phase battery-backup systems
In the event of grid failure, only single-phase PV inverters can feed their output power into a single-phase battery-backup grid. Three-phase PV inverters cannot feed into the single-phase battery-backup grid. Thus, three-phase PV inverters are not recommended for single-phase battery-backup systems. Possible solutions are:
- Replace the three-phase PV inverter by a combination of single-phase PV inverters, e.g. two Sunny Boy 4.0 inverters instead of one Sunny Tripower 8000TL.
- Select a sufficiently large battery capacity to ensure the supply of the loads from the battery only over the entire bridging time.
For the SMA Home Energy Solution with the Sunny Island for the battery-backup function, only PV inverters are suitable that can limit the active power depending on frequency (for information on frequency-dependent active power limitation see the Technical information "SMA GRID GUARD 10.0 - Grid Management Services via Inverter and System Controller"). In the following PV inverters you can activate frequency-dependent active power limitation as of the indicated firmware version.

1) With older firmware versions, a firmware update is required (see manual of the PV inverter).
