Fronius Primo GEN24

Device concept

The inverter transforms the direct current generated by the PV modules into al-
ternating current. This alternating current is fed into the public grid and syn-
chronized with the mains 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 in-
verter has backup power functions and switches to backup power mode if it has
been wired accordingly*.
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 inter-
rupt the supply of power into the grid.
The grid is monitored by monitoring the voltage, frequency and islanding condi-
tions.
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 bat-
tery* 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 obtained from the public grid in order to charge the battery*.
When its temperature gets too high, the inverter automatically reduces the out-
put 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 insufficient heat dissipation (for example, inadequate heat dissipation when in-
stalled in switch cabinets).
