Fronius Symo GEN24
Device concept The inverter transforms the direct current generated by the solar modules into alternating
current. This alternating current is fed into the public grid and synchronized with the grid
voltage in use. Moreover, the solar energy can also be stored in a connected battery for
later use.
The inverter is intended for use in grid-connected photovoltaic systems. The inverter has
a backup power function and switches to backup power mode if it has been wired ac-
cordingly*.
The inverter automatically monitors the public grid. Whenever conditions in the electric
grid are inconsistent with standard conditions (for example, grid switch-off, interruption),
the inverter will immediately stop producing power and interrupt the supply of power into
the grid.
The grid is monitored by monitoring the voltage, frequency and islanding conditions.
After installation and commissioning, the inverter's operation is fully automatic;
the inverter draws the maximum possible power from the PV modules.
Depending on the operating point, this power is used in the home, stored in a battery* or
fed into the grid.
As soon as the energy provided by the PV modules is no longer sufficient, the power
from the battery is fed into the home. Depending on the setting, power may also be ob-
tained from the public grid in order to charge the battery*.
When its temperature gets too high, the inverter automatically reduces the output or
charging power, or switches off completely, in order to protect itself.
Reasons for the temperature being too high include a high ambient temperature or insuf-
ficient heat dissipation (for example, inadequate heat dissipation when installed in switch
cabinets).
* Depending on the device variant, suitable battery, appropriate wiring, settings
and local standards and guidelines.
