Selecting the PV Inverter
You can install the following PV inverters in off-grid systems. The PV inverters must be equipped with the firmware version stated in the table or higher. If this is not the case, perform a firmware update (see PV inverter documentation).

Maximum PV system power
In off-grid systems, the maximum PV system power depends on the total power of the Sunny Island inverters.
Maximum output power of the PV system per SI4.4M: 4600 W
Maximum output power of the PV system per SI6.0H: 9200 W
Maximum output power of the PV system per SI8.0H: 12000 W
The maximum output power of the PV system must be observed to ensure stable operation of the off-grid system.
Configuration of Stand-Alone Mode
All mentioned inverters can be configurated for the stand-alone mode. To do this, there must be selected a country data set valid for the stand-alone mode or a valid set country standard (see the PV inverter documentation).
