Solar module
generates direct current
Inverter - Fronius GEN24 inverter
converts direct current into alternating current and charges the battery
(battery charging is only possible with inverters in the Fronius GEN24
Plus power category). The integrated system monitoring enables the
inverter to be integrated into a network by means of WLAN.

is coupled to the inverter on the direct current side, and stores electrical
energy.
Loads in the PV system
are the loads connected in the system.
Additional loads and producers in the system
are connected to the system by means of a Smart Meter.

for optimum energy management. The meter can be mounted in the
switch cabinet by the electrician performing the installation. Using sev-
eral smart meters enables energy profiling. Further loads or generators
in the system can be measured and monitored.
Backup power mode
the inverter is prepared for backup power mode. The backup power
mode must be implemented in the switch cabinet by the electrician per-
forming the installation. The PV system operates in a stand-alone man-
ner in backup power mode.

for using excess energy to heat water.
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.
Grid
supplies the loads in the system if insufficient power is being generated
by the solar modules or supplied by the battery.
PV Point is a non-uninterruptible backup power circuit which supplies electrical
devices with up to 3 kW if sufficient power is available from the PV mod-
ules or the battery.
