EG6548ex max voltage

[MesaGuy]

Hello,

I am about to hook up my two solar arrays

PV Array1 44.3 VOC x 4 = 177.2 volts (In series)

PV Array2 39.9VOC x 10 = 399 volts (In series)

I called signature solar and they said each mppt can take 500 volts.
I see this in the spec sheet: Max PV Array Open Circuit 500VDC
I just want to confirm this.

Thank you in advance!

That is correct, 500V max PV input for EACH MPPT. BTW, the VOC will go up as the temperature goes down so I usually factor in 15% less than max PV input Voltage just to be safe.
You were lucky that you talked to the right person at SS, not like the one below:

PV voltage on EG4 6500-EX-48

Question for everyone. Seems as if the manual did/does allow up to 500 volts per PV1 and 500 volts on PV2. (Yes it should be say 450v) When I called signature solar, the said noooo 500 volts TOTAL. As in 250 volts on pv1 and 250 on pv2. Certainly a big contradiction. Which is correct?????

Thank you Bud!

This is a huge relief.
