General
PV Point (OP) IMPORTANT!
If several backup power variants are available, please note that only one backup
power variant may be installed and configured.
With the PV Point, in the event of a
failure of the public grid, electrical
devices can be connected to the Op-
portunity Power (OP) terminal and
supplied with a maximum power of
3 kW, if enough power is available from
the PV 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 operat-
ing 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 configur-
ation must be set up during commissioning.
At 120 to 240 V output voltage, a maximum of 13 A AC continuous current 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 recommen-
ded to switch off non-essential loads during backup power mode. Overload capa-
city of 35% is possible for a duration of 5 seconds, depending on the capacity of
the solar modules and/or the battery at that moment in time.
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 in-
dicator. The maximum power in backup power mode according to the technical
data must be observed.
