The hybrid inverter converts the direct current generated by the solar modules into alter-
nating current. This alternating current is fed into the public grid synchronously with the grid
voltage. In addition, the solar energy can be stored in a connected Fronius Solar Battery
for use later on.
This version of the hybrid inverter is only intended for use in grid connected photovoltaic
systems. A device update is required from the manufacturer in order to generate power
separately from the public grid. As well as providing functional enhancements for the hard-
ware and software, this update also includes relevant user documentation.
The hybrid inverter is delivered ready for supplying emergency power.
Thanks to its design and the way it works, the inverter is extremely safe both to install and
to operate.
The inverter monitors the public grid automatically. In the event of abnormal grid condi-
tions, the inverter ceases operating immediately and stops feeding power into the grid (e.g.
if the grid is switched off, if there is an interruption, etc.).
Grid monitoring involves voltage, frequency and islanding detection monitoring.
Operation of the inverter is fully automatic.
The inverter is designed to get as much power out of the solar modules as possible.
Depending on the operating point, this power is either stored in the battery or it is fed into
the grid.
As soon as the solar modules stop providing sufficient energy, the power from the Fronius
Solar Battery is fed into the home network. Depending on the selected setting, power can
also be drawn from the public grid for the purpose of charging the battery.
If no power is available from the solar modules and no power is being drawn from the bat-
teries, the inverter disconnects the power electronics from the grid completely and ceases
operating. It retains all its settings and stored data.
If the inverter becomes too hot, it automatically reduces the current output power or current
charging power in order to protect itself.
Reasons for the inverter becoming too hot include the ambient temperature being too high
or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat
dissipation).

IMPORTANT! The Fronius Solar Battery is only to be switched on when the inverter is in
Standby mode.
