<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I've run a 3 Hp pump on a pair of Outback inverters, but
it's not a done deal. As the pumps age, they start getting stickier (read more
start up current needed to get them going) and wells often have silt which
builds up in the pipe and pump, adding to the start up surge.<o:p></o:p></p>
<div>
<p class=MsoNormal>I recently had a system with a one HP pump, that ran for
years on an SW4024, but when we went to grid tie with an Outback, it
overloaded. The cure was a fancy controller from Franklin that operates a
regular submersible pump as a constant pressure pump with no start up surge.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Then you'll find out how good your battery bank is, as a 3
HP pump will pull the battery voltage down rapidly. I'd have the Generac set to
fire up at a higher than normal voltage, well before the inverters cut out.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Too bad its a Generac.<o:p></o:p></p>

just inherited an off grid system with one VFX3524 inverter running the home
loads, and a 17kW Guardian Generac they use for charging (through an X-240 back
into the inverter) & to run their Franklin 3hp 240 VAC well pump, S. F. max
amp 17.0 ( rated on its controller)<o:p></o:p></span></p>

<div>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>This
is a really convoluted system as they have another 120/240 VAC Transformer to
have the inverter talk to the 240 volt signal the gen set needs to see. Yikes.<o:p></o:p></span></p>
</div>
<div>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'>So
I am proposing to add a second inverter if it can run the well pump and eliminate
the extra transformer. This will also reduce gen set run time in half while
battery charging, a big plus with the nice 24V Hawker battery bank, 1020 AH at
the 6 hour rate.<o:p></o:p></span></p>
