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.
The inverter is intended for use in grid-connected photovoltaic systems. For the
configuration of photovoltaic systems, Fronius provides the application Solar.cre-
ator, available at https://creator.fronius.com/.
The Fronius repowering tool (https://repowering.fronius.com/) supports in-
stallers and Fronius System Partners with repowering existing photovoltaic sys-
tems.
The inverter 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 (e.g., grid switch-off, inter-
ruption), the inverter will stop producing power and interrupt the supply of
power into the grid in conformance with IEEE standards.
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 or fed into the
grid.
As soon as the energy provided by the PV modules is no longer sufficient, the
power is drawn from the public grid.
When its temperature gets too high, the inverter automatically reduces the cur-
rent output 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 (e.g., inadequate heat dissipation when installed in
switch cabinets or in direct sunlight).
