3.2.5 Electrical functions
3.2.5.1 Fault signal relay
A potential-free relay contact is integrated in the inverter. The contact closes as soon as there is a fault during
operation.
For connection see section 7.3.1 on page 27.
DE Country-specifi c function
3.2.5.2 Fault signal relay/Powador-priwatt
A potential-free relay contact is integrated in the inverter. Use this contact for one of the following
functions:
• Fault signal relay
• Powador-priwatt
Powador-priwatt
The energy that is provided by the PV system can be put to use directly by the appliances that are
connected in your home. In "Powador-priwatt" mode, the potential-free contact takes care of this
function.
The contact closes if suffi cient PV energy is available over a period of 30 minutes. When the contact
closes, a visual or acoustic signal is emitted, e.g. from a signal lamp or siren (optional).
Activating the function (optional)
The "Powador-priwatt" function is not active in the unit's factory default state. You can obtain the
password for the function from your specialist retailer. The electrician then activates the function in
the confi guration menu (see section 8.3 on page 39).
Powador-priwatt switch (optional)
The potential-free contact switches larger appliances (e.g. air conditioning units) on and off . This
requires an external power supply (max. 30 V DC) and an external load relay.
Both can be obtained as part of the Powador-priwatt switch from your specialist retailer.

3.2.5.3 Power limitation (power control)
Since 1 January 2009, the German Renewable Energies Act (EEG) requires power limitation for systems
with an output of more than 100 kW. This limit value can be exceeded when using a unit group of
several inverters. Therefore, each inverter must have an option for limiting power, even if this is not
needed in a system that is smaller than 100 kW.
The power reduction is achieved using a ripple control receiver in KACO new energy GmbH inverters.
If necessary, the power supply company can reduce the power of the system remotely using an
additional device from the Powador proLOG family. The Powador-proLOG activates this function,
which is already integrated in the inverter. After a specifi ed period of time without any signal from the
power supply company, the inverter returns to normal operation. For information about Powador-
proLOG, contact your specialist retailer.
