Operating mode -
inverter with bat-
tery, AC-coupled
to another
inverter
Operating mode –
Inverter with bat-
tery and backup
power function
IMPORTANT!
In backup power mode, an increased nominal frequency is used in order to prevent
undesired parallel operation with other power generators.
In the fully equipped hybrid PV system, the inverter can:
- Supply loads in the house
- Store excess energy in the battery and/or feed it into the grid
- Supply connected loads in the event of a power failure
Operating mode –
Inverter with bat-
tery, Ohmpilot
and backup
power function
IMPORTANT!
In the fully equipped hybrid PV system with a Fronius Ohmpilot, the Ohmpilot cannot be
operated in the event of a power failure for regulatory reasons. It is therefore sensible to
install the Ohmpilot outside of the backup power branch.
