[RE-wrenches] Sol-Ark install

[scot.arey at solarcentex.com]

I agree with an earlier response…isn’t this a NABCEP PV Installation Professional-only forum?  The original question is DC-string design 101. Jerry is spot on for coldest temp adjustments, RSD considerations if required. But selecting a home run wire for separate string inputs to the inverter??? How can this be asked here?

Ron, are you NABCEP PV Installation Pro certified?

Need more than this, we have amperage, we need distance, temp, # of wires per conduit, also at 480 you may want to verify cold temp for over the top voltage @ VOC, any RSD device(s) being used? Help to have total module count, as an example use a combiner to make 4 strings, 2 of equal voltage per input. For battery backup or off grid, Solark is the easiest you will get.

Hi Wrenches, trying to wrap my head around a first time Sol-Ark install. Because the max DC voltage is 500v at 18a  and the PV I’m using is 40v DC each I will have to create three strings each 480v. What would be the best choice for a home run wire? I’ve always used smaller strings with micro inverters, a combiner at the array and a single Teck home run cable but the string inverter presents a different scenario and it looks like I’ll need to use three home run cables, one for each string.
