Maximum Voltage: The open circuit voltage, V
OC
, must never exceed 600 V
DC
under any conditions. The voltage generated by PV modules is inversely
proportional to the temperature; at lower temperatures the PV voltage increases
from the nameplate rating and at higher temperatures the PV voltage decreases
from the nameplate rating.
NOTICE
Ensure the DC switch in the Stringbox is in the OFF position, when removing the
lower cover to access the connection terminals.
