CONNECTION LIMIT OF THE MODULES
The thickness and composition of the back sheet provides Helios Solar Works modules with electrical
insulation of 600 V
DC
subject as per UL regulation. As a result, when installing within North America:
6T series module can be connected to each other in groups of up to 13.*
7T2 series module can be connected to each other in groups of up to 11.*
9T6 series module can be connected to each other in groups of up to 8.*
* values were calculated using standard test conditions (STC).
Back sheet thickness and composition are also IEC certified, providing Helios Solar Works modules with
electrical insulation of 1000 V
DC.
Therefore, when installing modules where IEC standards hold precedence
6T series module can be connected to each other in groups of up to 21.*
7T2 series module can be connected to each other in groups of up to 17.*
9T6 series module can be connected to each other in groups of up to 13.*
* values were calculated using standard test conditions (STC).
There is no limit to the connection of modules in parallel, as the operation of one does not affect the others,
however, they must all work at the same voltage level. Therefore, all the modules connected in parallel
must have an equal number of cells, in order to avoid the recirculation of current between rows of modules.
In case of a parallel connection, the new maximum intensity allowable to the inverter is the limit of the
number of modules to be installed.
