I talked to SolArk about the input amperage limitation on a recent
project. Someone correct me if I am wrong, but SolArk does automatically
limit excess amperage. We were very close on the limit and it made no
sense to me that they would design something with parallel MPPT that
limit one to

Hi, Ron, Yes, you must be careful of the MPPT inputs. You state Sol-Ark
has an 18 amp max input, meaning you can not have more than 1 string
supplying an MPPT if your 60 cell modules are 10 amps Isc. You state
Sol-Ark has a maximum voltage per MPPT of 500 volts, this voltage is *not
Voc x number
I feel the same way about the Outback Radian GSLC box, once it's fully
wired there's no room whatsoever, and sometimes you have to remove
breakers and layers of wiring to re-access things for debug. Don't know how
it meets code and ETL approval for wire space.

This problem is not limited to one manufacturer. One example is the Enphase
smart controller. While the small holes are big enough for #6 ground and
neutral, you have to strip the wires perfectly and have the hand of a heart
surgeon to get them in there. And conduit entry is a royal pain because
We have done one Solark installation & I was shocked as to the lack of ground
wire landing terminals & space. We added a 12126 metal box below to ease the #
of entrances to two 11/4”.
I jumpered a # 8 to a second ground bar to allow for additional landing
locations. I called Solark to question
Ron
The Sol-Ark has two MPPT channels and has two separate landing spots for each
MPPT channels. Each landing pair needs matching strings. 8 AWG wire barely fits
so the Sol-Ark PV terminals so they may only be rated for 10AWG.
I’m assuming you have a ground array The most common stringing
Hi gang, let's take any further discussion of Wrench List qualifications
off-list, please email me directly with any questions or concerns.
First, this is not a NABCEP-only list. If I had to guess, less than half of you
have pro installer certifications. In fact, this list predates NABCEP and
NABCEP PV Installation Pro certified?

Ron, are you NABCEP PV Installation Pro certified?

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
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

Hi Wrenches, trying to wrap my head around a first time Sol-Ark install.

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
