3.0 Mechanical / electrical properties
The rated electrical performance data for the modules is measured under standard test
conditions (STC) of irradiance of 1000 w/m2, AM 1.5, and cell temperature of 25 °C.
The specific electrical and mechanical performance parameters of Sunman eArche
modules are included in Annex A of this installation manual.
The main electrical
performance parameters under STC conditions are also marked on the nameplate of
each module.
The maximum system voltage for all modules is 1000V.
In some cases, the current or voltage generated by the module may be greater than the
optimal operating current or voltage of its standard test condition (STC).
Therefore,
when determining the component rating and load value, the module open circuit voltage
and short circuit current at STC should be multiplied by 1.25.When determining the
appropriate wire and fuse specifications, the short-circuit current needs to be multiplied
by 1.25 (ie, the total is multiplied by 1.56) according to local regulations.
