Grid
supplies the loads in the system if insufficient power is being gen-
erated by the PV modules or supplied by the battery.
Inverter in the system
e. g. Fronius Primo, Fronius Symo, etc.
Utility meter
Measures the measurement data relevant for billing amounts of
energy (in particular kilowatt hours of energy sourced from the
grid and energy fed into the grid). Based on the relevant billing
data, the electricity retailer will invoice the energy sourced from
the grid and the purchaser of the surplus energy will reimburse
the energy fed into the grid.
Primary meter
Records the system's load curve and provides measurement data
for energy profiling in Fronius Solar.web. The primary meter also
controls the dynamic feed-in control.
Secondary meter
Records the load curve of individual loads (e.g. washing machine,
lamps, TV, heat pump, etc.) in the consumption branch and
provides measurement data for energy profiling in Fronius Sol-
ar.web.
Producer meter
Records the load curve of individual producers (e.g. wind power
plant) in the consumption branch and provides measurement data
for energy profiling in Fronius Solar.web.
Modbus RTU slave
e. g. Fronius Ohmpilot, Fronius Solar Battery, etc.
Loads in the system
e. g. washing machine, lamps, TV, etc.
Additional loads in the system
e. g. heat pump
Additional producers in the system
e. g. wind power plant
Terminating resistor
R 120 Ohm
