Is there any recommended safety margin or factor when remaining below Voc on solar string input?
I have 10 panels with a Open-Circuit Voltage of 49.35. My EG4-6500 inverter has a max Open-Circuit Voltage of 500 Volts.
My 10 panels would have a max Voc of 493.5 Volts.
That's so close to my 500 V max threshold, it's a little worrisome as I live in a hot, desert climate where we're pushing the maximum temps seen on Earth.
Should I be worried? Would you be?
Should I setup 2 strings in parallel made up of 5 panels in series? That'd give me 250 V VOC and around 15 AMPs each and us a Y-Combiner to connect the 2 strings?
Thanks!
