2.10 PV 

Connection

WARNING

PV modules generate voltage when exposed to light.
Do NOT connect PV to earth.

Illustration 2.20 Do Not Connect PV to Earth

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

1.

Mount Sunclix connectors (not supplied) on the
PV cables, according to 

Illustration 2.21

.

2.

Verify the polarity and maximum voltage of the
PV arrays by measuring the PV open-circuit
voltage. See 

Illustration 2.21

.

The PV open-circuit voltage must not
exceed 1000 V DC. The inverter is
protected against reversed polarity and
will not generate power until the
polarity is correct. Reversed polarity
damages neither the inverter nor the
connectors.

Illustration 2.21 Correct Polarity: Mounting Sunclix Connector

on Cable

1.

Measure the DC voltage between the positive
terminal 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.

2.

Locate and fix the failure before continuing.

3.

Repeat this procedure for all arrays. Uneven distri-
bution of input power on the PV inputs is
permitted, if:

The individual input is not overloaded.
The maximum permissible load per
input is 8000 W.

The maximum short-circuit current of
the PV modules at STC (Standard Test
Conditions) does not exceed 13.5 A per
input.
