Well i agree with every one, tha Samlex is great, morning atar charge controllers again grean, and the question about the operating volts also great, l have done stuff very close and the battery volts may have a wide range<br>

What about building a 30 vdc system (5 x 6v batteries in series)
and adjust the settings on a Midnite Classic to work with that? How
tight does the 30 vdc output need to be?<br>
<br>
On inverters, I've had trouble with the Suresine, basically not
working with GFCI outlets.<br>
I keep trying different models of GFCIs, but they keep randomly
tripping on 2 different systems. <br>
Morningstar's list of "approved" GFCIs doesn't list any currently
manufactured models, while calls to their tech support yields "Oh,
that shouldn't be a problem, it should work with all GFCIs..."<br>
Way too many free trips out trying to fix this, so I may have to
abandon GFCI protection, or replace the inverters. <br>
My suggestion for that small load: Exeltech 125. Better than grid
waveform, and I recently pulled one out of corroded outdoor
enclosure almost 15 years old: it looked terrible, but was still
working fine. It would also be lower cost and fit in a smaller
enclosure.<br>

<div>30VDC is kind of odd, but 36VDC is common. The folks at
Solar Converters might be able to fix you up with a custom
one, or perhaps 36V is within the sat unit's input range.</div>
<div>As for the inverter, I've never gone wrong with the
Morningstar SureSine. Slick little unit.<br>
