Is there a rule for mixing different size panels to connect to an mppt charge controller?
I have a set of 24V panels. (6) are 320 watt and (2) is 370watt. They are all canadian solar brand.
My 60A mppt controller can accept a total of (
of these panels for charging my 48V battery bank. What i need to know is if the Vmp/Voc of the panels are off by say 1 or 2volts difference between them will this cause any operating issue from the mppt controller?
Will i still get optimum performance/tracking from it? I assume that the 370watt will decrease in wattage and perform at 320watt max will that be the case?
Please advise me as to how much difference you can have in terms of mixing panels with different open circuit voltage and optimum operating voltage and then connecting them to an mppt charge controller and still expect excellent performance from it in regards to producing close to your overall wattage and excellent tracking ability with the different voltage strings.
