PV module
generates direct current
Fronius GEN24 inverter
converts direct current into alternating current and charges the battery
(charging the battery is dependent on the device variant, suitable batter-
ies, the requisite cabling and settings). The integrated system monitoring
enables the inverter to be integrated into a network by means of WLAN.
Additional inverter in the system
converts the direct current into alternating current. However, it cannot
charge a battery, and is not available in backup power mode.
Battery
is coupled to the inverter on the direct current side, and stores electrical
energy.
Fronius Ohmpilot
for using excess energy to heat water.
Primary meter
records the system's load curve and provides measurement data for en-
ergy 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 Solar.web.
Loads in the PV system
are the loads connected in the system.
Additional loads and generators in the system
are connected to the system by means of a Smart Meter.
PV Point
is a non-uninterruptible single-phase backup power circuit which sup-
plies electrical devices with up to 3 kW if sufficient power is available
from the PV modules or the battery.
Grid
supplies the loads in the system if insufficient power is being generated
by the PV modules or supplied by the battery.
