My maximum voltage including temperature Coefficient appears to be 324.3 and the mppt 6548 has a max input of 250. Would this cause it to cause an over voltage alarm on the inverter (if it has one). For temperature I'm using outside air temp. Is this the correct way to do it? Would this actually cause harm to the inverter? This is the math I used in case I messed up.
voc = 46.8v
# of panels 5
Temperature Coefficient (Voc) -0.28 % / °C
Lowest temp will be around -15 F / -26.11C
Nominal operating temperature rated at 41 ± 3°
I calculated 67c difference from nominal operating temperature to max lowest temperature as 67.41C
So 67.41*.28 is 18.8748 voltage increase so 5 panels voc 18.8748 * 5 panels is 94.35 extra volts.
Total voltage 324.3
Specs to the panels can be found here: https://store.santansolar.com/wp-co...dian_Solar-Datasheet-BiHiKu_CS3W-PB-AG_EN.pdf The 390w panel.
