I will install a PV system in a very hot and high humidity place in the Amazon region in Colombia. We are planning to use a MONO PERC half cell PV module with Voc= 49,3V (Longi LR4-72HPH-450M). I would like to know if any of you have experience with this type of PV modules in a hot place. My main concern is to damage the MPPT going beyond its maximum voltage input.
If my array has 3 modules in series, I will get 147,9V but I am above the Maximum PV open circuit voltage from the datasheet: 145V start-up and operating maximum. However, knowing that the installation will be in a very hot place, the voltage will drop a bite.
From the configuration spreadsheet, I found that my limit temperature is 20°C. Below it (e.g. 19°C) I will damage the MPPT.
I think that it could be better to have 2 PV modules in series, in order to be completely sure about voltage limits; but I would like to hear from you guys: what do you think/suggest?
Thanks in advance,
