Module Selection

For detailed key electrical data, please refer to the actual data sheet 
referring to the relevant Module (available at www.q-cells.com).

 

Ä

For maximum energy yields, mismatches of specified electric 
current (I

MPP

) of more than 5 % should be avoided for all modules 

connected in series.

Safety Factor

During normal operation, a module may generate a greater current 
and / or higher voltage than that determined under standardised 
test conditions. Please use a safety factor of 1.25 for the following:

• 

Calculating the voltage measurement values (V

OC

) of components

• 

Calculating the current measurement values (I

SC

) of conductors

• 

Sizing of control systems connected to the outlets of the solar 
modules

 

Ä

Please refer to the latest revision of AS / NZS 5033 (including 
all relevant amendments) and the Clean Energy Council 
Guidelines (for Australia).

Series Connection

Connection of modules in series is only permitted up to the 
maximum system voltage as listed in the applicable data sheet 
of all the relevant modules to be installed.

 

Ä

Take into account all possible operating situations and all 
relevant technical norms and regulations when designing the 
system. It has to be ensured that the maximum system voltage, 
including all necessary safety margins, is not exceeded.

 

Ä

Take the voltage limit of the inverter into account when 
determining the maximum number of modules in the string. 

Parallel Connection

Modules may be damaged by the occurrence of reverse currents 
(caused by module defects, ground leaks, or defective insulation).

 

Ä

Ensure that the maximum reverse current load capacity 
indicated in the data sheet is met.

In order to limit reverse currents that may occur, we recommend 
using the following safety options:

1) 

Layout with a limited number of 
parallel connected strings :

Please refer to the latest revision of AS / NZS 5033 (including all
relevant amendments) for parallel string overcurrent protection
requirements.

2) 

Layout with string fuses :

Use overcurrent devices (e.g. fuses) according to the relevant 
standards in each string. Use gPV-fuses according to IEC 60269-6. 
Observe the maximum permitted number of strings as indicated 
in the specifications provided by the respective string fuse 
manufacturer and the technical guidelines.

NOTE!

When installing different product versions, the lowest minimum 
permitted reverse current load capacity applies.

Inverters

Inverters with or without transformers may be used.

3.1  SAFETY AND TRANSPORT

 

Ä

Leave modules in their original packaging until 
installation.

 

Ä

Store the modules securely in cool and dry 
rooms. The packaging is not weatherproof.

 

Ä

Inspect the packaging for damages.

 

Ä

Contact the transport company regarding 
any damage to the packaging and follow their 
instructions.

 

Ä

Follow any instructions on the packaging.

 

Ä

Ensure that all personnel are aware of and 
adhere to accident-prevention and safety 
regulations.

 

Ä

While working wear clean gloves.
