Fronius Symo GEN24 10.0, Operating Instructions Manual, Page: 31 / 120

General
PV Point (OP) With the PV Point, in the event of a failure
of the public grid, electrical devices can be
connected to the Opportunity Power (OP)
terminal and supplied with a maximum
power of 3 kW, if enough power is avail-
able from the solar modules or an optional
battery. In grid-connected operation, the
OP terminal is not supplied with voltage,
therefore the connected loads will not be
supplied with power in this operating
mode.
IMPORTANT!
A relay-based network switching setup is
not possible.
Explanation - PV
Point (OP) The inverter can provide 120 to 240 V at the PV Point. A corresponding configuration
must be set up during commissioning.
At 120 to 240 V output voltage, a maximum of 13 A AC power is available.
For example:
120 V = max. 1.5 kW
230 V = max. 3 kW
In backup power mode, some electrical appliances cannot function properly as starting
currents are too high (for example, fridges and freezers). It is recommended to switch off
non-essential loads during backup power mode. Overload capacity of 20% is possible for
a duration of 5 seconds, depending on the capacity of the solar modules and/or the bat-
tery.
There is a brief interruption when switching from grid-connected mode to backup power
mode. For this reason, the backup power function cannot be used as an uninterruptible
power supply, for example for computers.
If no energy from the battery or the solar modules is available in backup power mode,
backup power mode ends automatically. If sufficient energy becomes available from the
solar modules once again, backup power mode starts again automatically.
In the event of excessive consumption, backup power mode is stopped and the "backup
power overload" status code is displayed on the inverter's LED status indicator. The max-
imum power in backup power mode according to the technical data must be observed.
