PV module
generates direct current
Fronius GEN24 inverter
converts direct current into alternating current. The integrated system
monitoring enables the inverter to be integrated into a network by
means of WLAN or LAN.
Additional inverter in the system
converts the direct current into alternating current. However, it can-
not charge a battery, and is not available in backup power mode.
Primary meter
records the load curve of the system and makes the measured data
available for energy profiling in Fronius Solar.web. The primary meter
also regulates the dynamic feed-in control.
Secondary meter
records the load curve of individual loads (e.g., washing machine,
lights, television, heat pump, etc.) in the load branch and makes the
measured data available for energy profiling in Fronius Solar.web.
Loads in the system
are the loads connected in the system.
Additional loads and producers in the system
which are connected to the system by means of a Smart Meter.
PV Point
is a non-interruption-free 1‑phase backup power circuit, which sup-
plies electrical devices up to a maximum output of 3.12 kW, provided
sufficient power is available from the PV modules.
Grid
supplies the loads in the system if insufficient power is being gener-
ated by the PV modules.
