The various operating modes
Operating modes
– Explanation of
symbols
Solar module
Generates direct current
Inverter – Fronius hybrid
Converts the direct current into alternating current and charges the bat-
tery. Thanks to the built-in system monitoring function, the inverter can
be integrated into a network using WLAN technology.
Battery
Connected to the inverter on the DC side and used to store electrical
energy.
Photovoltaic system consumers
The consumers connected to the PV system (single or three-phase)
Meter – Fronius Smart Meter
For optimum energy management. You can have the meter installed in a
switch cabinet by your electrical installer. Energy profiling is possible
through the use of several Smart Meters. Additional consumers or gen-
erators in the system can be measured and monitored.
Emergency power function
The inverter is delivered ready for supplying emergency power.
However, the electrical installer must set up the emergency power func-
tion in the switch cabinet. In emergency power mode, the PV system
operates as a stand-alone island.
Fronius Ohmpilot
To use surplus energy to heat water.
Additional inverter in the system (e.g. Fronius Symo)
Converts the direct current into alternating current. Cannot, however, be
used to charge batteries and is not available to provide emergency
power.
Grid
Operating mode:
Inverter
The Fronius hybrid inverter can be used purely as an inverter without a battery connec-
ted to it.
