I'm concerned that a microinverter - module pair that has been specified
by a supplier may not work. The maximum power voltage is very close to
the minimum starting voltage. The Voc is adequately high.
An Aptos DNA-120-MF26-365W is paired with an Enphase IQ 7A
• Minimum start voltage of the inverter is 33 V
• Vmmp of the module is 33.96 V
• Voc of the module is 40.7 V
Is the 33 V starting voltage going to be a problem with a module STC Max
power voltage of 33.96 V? Is it the Voc that determines the starting of
the inverter or the Vmmp?
Thanks,
Drake
