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.

3.

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.

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.

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. U

OC

, STC x 1.13 ≤ U

MAX
