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 battery. 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 elec-
trical 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 in-
stalled in a switch cabinet by your electrical installer. Energy pro-
filing is possible through the use of several Smart Meters. Addi-
tional consumers or generators 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
function 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.

Operating mode:
Inverter The Fronius hybrid inverter can be used purely as an inverter without a battery
connected to it.
