William,
While it will work, the only big reason to do it is for 240V loads. With
your experience, I suspect that you know this. The penalty is 32W idle, and
both inverters shut off if one overloads.
Some years ago we did a large GTWB system with a 4048 and a 5548 that were
not stacked, but served
Hi William,
I'm interpreting your question to be mostly aimed at finding out how roof
color affects the temperature inside your house. It makes a heckuva
difference. Conventional wisdom holds true... Lighter colors absorb less
heat than darker ones. If you are going to stick with comp, from a ther
William,
My first company truck was a 1970 Land Rover 109 Diesel, that had
something called a "tropical roof", which was a second roof surface
(aluminum like the rest of the car) mounted on standoffs about 2" above
the actual cab roof. There were also scuttle flaps that allowed inside
air to
William,
There's lots of good technical data (and also wild advertising claims) on
the www if you google "cool roofs". Smooth white roofs (metal or non-metal)
reflect heat well. Several years ago the US Bureau of Standards tested
composition shingles and found that so-called white comp shingle
William, the 6 years I spent in he Palm Springs area gave me a lot of exposure
to what works and what doesn't as far as roofing material. The longest lasting
and best insulators were standing seam metal and vinyl covered foam. A white
rooffing material made an incredible difference in tempretur
Hi William,
Technically, it will work... officially, we do not support stacking
anything except like items.
The part number for the stacking cable is just SWI - there are lots of
dealers and distributors that still have stock, though we are out.
Hope this gives you some guidance,
Best,
Mark

This is a duplicate of a message posted to the Wrenches forum.
Is it possible to pair a Xantrex SW4048 with an SW5548? Has anyone tried
it? Does anyone have a spare sync cable they might like to sell?
Thanks in advance. And thanks for your quick response on various questions

Hi William. White roofs can be very effective. SMUD has an extensive white
roofs program in Sacramento. Not only do they help cool an individual building,
but in inner-city situations they can decrease ambient temperatures.

Friends:
I have an energy question on a personal project. We are adding two rooms
to our house and it is time to select roofing colors. Nothing will match
the weird comp shingles already on our roof, so we are going to not match
and re-roof the rest of the house later. In the meantime, I ne
