Hi Jay,
The C-40 is probably your cheapest bet, although not sealed.
Or...maybe use three Evergreen ES-A 215W modules in series without a
controller? Vmp would be 55.2V at STC, but maybe still too risky as the Voc
would be over 68V at STC. Depends on how much the cart gets used, and the
number
Morningstar makes a 48V Prostar.

Hi Jay,
We really like Phocos controllers for smaller applications. Check out
"The DIngo".

HI All,
Any recommendations on a small 7-10 amp 48v controller, preferably sealed.

I checked out this instrument when it came out a couple years ago. In my
opinion, there were two fatal flaws with it.
1. It only evaluates azimuths +/- 45 degrees of true south...
2. It required too many steps. I.e. Shoot at least 7 images; Download to
your computer; Stitch the images tog
Hi Kent:
At my site, the wire is directly above the module, and the module is
oriented with a 210 deg. AZ, and the shadow is there most of the day. It is a
very clear, visible shadow and has had no effect on output. Strangely, that
module has produced more power than any other module on th

Depending on the hours that the shadow is on the module, that indeed
may be the case. I have a similar circumstance with a recent Enphase
installation too: the shadow of a triplex service cable about 6 feet
away shadows the lower half of the array from sunrise until 7:00 am (in

Hi Kent:
I am sure that aerial wires have very little impact on system outputs. I
just checked the Enphase Enlighten data for a system I recently installed,
which
had a 1-2" to 3/4" wire bundle running just 5' above a solar modules. The wire

Benn,
At 25 ft a 1-inch power line subtends an angle of 0.2 degree. The sun
subtends an angle of 0.5 degree, so the power line will not make a
dark shadow on the modules - only 50% of the light can be blocked.
Depending on the distance from the module to the wire, along the ray to
the sun,
Considering that most of us have been designing and installing solar for a
long time, we are all pretty comfortable with the Solar Pathfinder (or even the
Solar Site Selector,) and I was resistant to upgrading to the Suneye. However,
in recent years, I have moved to the Solmetric Suneye, an
