<DIV>Dear wrenches, going to look at a system installed by others and would
like some input from some of you with more off grid experience than I have ( 4
systems over the years). the system was put on a new home - off grid 20 sharp
ND123UJF panels 4 modules in series - 5 parrallel strings, 2460
total array dc voltage. mppt 60-150 <SPAN class=yshortcuts id=lw_1219089563_0
style="BACKGROUND: none transparent scroll repeat 0% 0%; CURSOR: hand; BORDER-BOTTOM: #0066cc 1px dashed">charge
controller</SPAN>, 12 sun extender sealed <SPAN class=yshortcuts
id=lw_1219089563_1
style="CURSOR: hand; BORDER-BOTTOM: #0066cc 1px dashed; BACKGROUND-COLOR: #dceeff">AGM
batteries</SPAN>, 305 AH at 12 vdc, wired for 915 AH at 48 volt DC. The system
is tripping off when the AC unit trys to start - AC is comfortmaker 3.5 ton 13
seer. They say start up inrush is 104 amps (sounds high to me) and they put a
DST 10 <SPAN class=yshortcuts id=lw_1219089563_2
style="CURSOR: hand; BORDER-BOTTOM: #0066cc 1px dashed">soft start</SPAN> on
the unit (I think that's just a big capacitor). I haven't been on site yet but
it sounds to me that they just didn't design enough inverter capacity
into the system...... What are your thoughts?</DIV>
