Module Selection
For detailed key electrical data, please refer to the product data
sheet for the respective product.
Ä
Only connect modules of the same type and the same power
class.
Safety Factor
During normal operation, a module may generate a greater current
and / or higher voltage than that determined under standardized test
conditions. Accordingly, the values of I
SC
and V
OC
marked on the
module should be multiplied by a facot of 1.25 when determining:
•
the component voltage ratings,
•
conductor ampacities,
•
fuse sizes,
•
size of controls connected to the PV output.
Refer to Section 690-8 of the National Electrical Code for an
additional multiplying factor of 125 percent (80 percent derating)
which might be applicable.
Ä
Please follow the valid national guidelines for the installation
of electrical systems (refer to section 690-8 of the NEC for an
additional multiplying factor of 125 percent [80 percent derating]
which may be applicable).
Series Connection
Connection of modules in series is only permitted up to the
maximum system voltage as listed in the applicable data sheet.
Ä
Take into account all possible operating situations and all relevant
technical norms and regulations when designing the system.
This will ensure 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 observed.
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 :
Without undertaking further current blocking measures, a maximum
of two module strings may be operated in parallel on an inverter or
MPP tracker.
2) Layout with string fuses :
place fuses for each string of modules at the plus and minus ends.
Observe the maximum permitted number of strings as indicated
in the specifications provided by the respective string fuse manu-
facturer 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.
