Installing the Fronius Symo Hybrid with the external
battery
Tips before com-
missioning
It can take up to two hours to update the inverter. During this time the inverter must be con-
nected to an AC power source. To save time during installation, work may still be carried
out in a non-live area of the system while the update is in progress.
More information on the update process can be found under "Software version of the
Fronius system monitoring" on page 14
