Input DC (PV) Specifications
Input (DC) from PV array:
Because the PV modules also have a reduction in voltage at high cell temperatures, you
must make sure the MPPT voltage of the strings will not drop below the minimum
inverter DC input voltage in very hot temperature conditions.
Both the maximum open circuit voltage (OCV) when at cold extreme and minimum
MPPT voltage when at hot extreme can be calculated for a PV module using its
specification sheet. PV module string sizing can then be used to determine how many
modules can be used in a string. Visit
