parts available from the supplier should be used. If non­original spare parts are used, the compliance with CE
guidelines in respect of electrical safety, EMC and machine
safety is not guaranteed.
The temperature of the cooling racks and components
inside the inverter may exceed 70ºC. Observe the danger
of burn injury.

CAUTION

Functional safety parameters
Never change the parameters of the inverter without
authorisation from the local energy supply company and
instructions from Danfoss.
Unauthorised changes of functional safety parameters may
cause injury or accidents to people or inverter.
Additionally, it will lead to the cancellation of all inverter

Hazards of PV Systems

DC voltages up to 1000 V are present in a PV system even
when the AC grid is disconnected. Faults or inappropriate
use may lead to electric arcing.

WARNING

Do not work on the inverter while disconnecting DC and
AC.

The short-circuit current of the photovoltaic panels is only
slightly higher than the maximum operating current and
depends on the level of solar irradiation.

PV Load Switch

The PV load switch (1) enables safe disconnection of DC
current.

2.7 PV Connection

WARNING

Do NOT connect PV to earth!

NOTE

Use a suitable voltmeter that can measure up to 1000 V
DC.

PV Connection Procedure:

1. First verify the polarity and maximum voltage of
the PV arrays by measuring the PV open-circuit
voltage. The PV open-circuit voltage must not
exceed 1000 V DC.

2. Measure the DC voltage between the plus­terminal of the PV array and Earth (or the green/
yellow PE cable). The voltage measured should
approximate zero. If the voltage is constant and
not zero there is an insulation failure somewhere
in the PV array. Locate and fix the failure before
continuing.

3. Repeat this procedure for all arrays. It is allowed
to distribute the input power on the inputs
unevenly, presuming that:

•

The nom. PV power of the inverter is
not exceeded (6.2 / 8.2 / 10.3 / 12.9 /

15.5 kW).

•

The maximum short-circuit current of
the PV modules must not exceed 12 A
per input.

4. On the inverter turn the PV load switch into off
position. Connect the PV cables by means of MC4
connectors. Ensure correct polarity! The PV load
switch can now be switched on when required.

Illustration 2.22 DC Connection Area

CAUTION

When unmated, the MC4 connectors are not IP54. Intrusion
of moisture may occur. In situations where the PV
connectors are not fitted, a seal cap must be mounted
(included in the scope of the delivery). All inverters with
MC4 connections are delivered with seal caps on inputs 2
and 3. During installation, the seal caps of those inputs
that are to be used are discarded.

NOTE

The inverter is protected against reversed polarity but it
will not generate power until the polarity is corrected. To
achieve optimum production, the open-circuit voltage
(STC) of the PV modules must be lower than the max.
input voltage of the inverter (see 4.1 General Data),
multiplied with a factor of 1.13. UOC, STC x 1.13 ≤ U

MAX

, inv.

2.8 Auxiliary Input/Output
