General

Fronius explicitly points out that the third-party batteries are not Fronius
products. Fronius is not the manufacturer, distributor or retailer of these batter-
ies. Fronius accepts no liability and offers no service or guarantees for these bat-
teries.
Obsolete firmware/software states may lead to incompatibilities between the in-
verter and the battery. In this case, the following steps are to be performed:

Read this document and the Installation Instructions before installing and com-
missioning the external battery. The documentation is either enclosed with the
external battery or can be obtained from the battery manufacturer or their ser-
vice partners

Limitations in
If the DC voltage exceeds 520 V, the battery can no longer be charged or dis-
operation charged. The voltage of 520 V is rarely exceeded during normal operation of the
inverter.
When the output power of the inverter is reduced, the operating point shifts to-
wards higher DC voltages. The following conditions during normal operation can
lead to the DC voltage of 520 V being exceeded:

Update battery software – see the battery documentation.
Update inverter firmware – see
Overdimensioning of the PV generator.
Feed-in limitation (e.g. zero feed-in).
Specifications of the grid operator (e.g. mains voltage-dependent power re-
duction).
Backup power mode. If the 520 V voltage is exceeded during backup power,
backup power operation may be restricted. Therefore, an open circuit voltage
of max. 520 V is recommended.
