5 NETWORK CONNECTION P
5.1 Principles for determination of the network P
connection point
The decisive aspect for evaluation of the network P
connection is always the behavior of the PGS at
the network connection point or PCC.
The PGS is fully separated from any other P
current-using equipment of the customer.

Page 11 of 176
VDE-AR-N 4105
In general rule, PGS are installed on different P

plots shall not be connected at the same network
connection point. PGS installed on a building may
be connected at the same network connection
point
All separated supply points shall be permanently P
marked with “Sectioning point: power generation
system/supply network”.
In German: „Trennstelle Erzeugungsanlage -
´Versorgungsnetz“
For the purpose of evaluating the connection with P
regard to the network reactions, the impedance of
the network at the PCC (network short-circuit
power, resonances), the maximum apparent
connection power and the type of PGS are
considered. If more than one PGS is connected
in the same network, their total effect shall be
considered.
5.2 Rating of the network equipment P

transformers and other network equipment. The
rating of the network equipment shall be

voltage change does not exceed a value of 3% of
Un at the PCC.

once every 10 min.

current ivzul of Table 1 and network short-circuit
power.

9 Verification of the electrical properties N/A

9.1 General N/A
For every PGS, the type-specific certificate of N/A
conformity in accordance with G.2 is required.
This certificate of conformity shows the electrical
properties of the PGU in order to demonstrate its
conformity with the requirements of this VDE
application guide.
In addition, a type-specific certificate of N/A
conformity in accordance with G.3 shall be
submitted to the network operator for the network
protection and system protection confirming the
protective function and the protection settings of
this VDE application guide.
The certificate of conformity issued for the PGU N/A
and the NS protection shall confirm their
conformity with the requirements of this VDE
application guide at least with regard to the
properties described in clause 9.2 to 9.4. For this,
the following properties shall be verified by
measurement. Until such time when a test
specification is available, the conformity shall be
verified in accordance with Clause G.2 and F.3
for the PGU and Clause G.3 and F.4 for the NS
protection.
9.2 Verification of the feed-in power N/A
9.2.1 Verification of the feed-in active power N/A

Page 23 of 176
VDE-AR-N 4105
For PGU, it is sufficient to indicate the maximum N/A

active power feed-in
9.2.2 Verification of the reactive power values N/A
Indication of the maximum inductive reactive N/A
power (under-excited) and maximum capacitive
reactive power (over-excited) as a function of the
feed-in active power is required. For this, at least
the conditions given in 5.7.5 shall be satisfied.
To check the compliance with the predefined N/A
displacement factor cosφ, measurement in the
type testing shall not be deviated from the setting
for more than 0.01.
For PGU with a generator directly coupled to the N/A

reached within 60s. The maximum deviation for
cosφ at nominal voltage shall be 0.02.

The maximum apparent power of the inverter is limited to 66 kVA. If setting cos φ≠1, the maximum active
power is reduced accordingly. The active power 100% P/Pn is therefore only achieved when cos φ = 1.,
however, the maximum SEmax was also measured under the P=S*0.8 or 0.9 condition.
