<div>You don't list what the inverter is, but you might find that the battery voltage is dropping like lead when when the AC starts. If the system always started he AC look to the batteries, not good choice IMHO</div>
<div>Another thing is, systems tend to grow with time and out grow the systems intended loads.</div>
<div>How old is thw system?<br> </div>
<div>Later,</div>

<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 style="BACKGROUND: none transparent scroll repeat 0% 0%; BORDER-BOTTOM: #0066cc 1px dashed">charge controller</span>, 12 sun extender sealed <span style="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 style="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>
