To add a bit:<br><br>Magnum are exceptionally easy to set up and program. The user interface is well designed. A few issues to be aware of from my experience: <br>- All of our Magnum-based off grid systems have been single inverter. At 4 kW, a single inverter may not be enough for that particular 3hp motor - best to CYA with the customer on the possible need for a stacked pair. <br>- Magnum allows a pretty wide voltage dip to accomplish surge capacity, so when the saw starts, expect lights to flicker. Our CF bulbs flicker when the refrigerator starts.<br><br>Our trial with Apollo a couple of years ago was probably the single most negative experience with an inverter manufacturer of my career. Kevin's comment that the most basic programming required hooking up to a computer is accurate. The computer must have their proprietary software installed, and the hookup was necessary even to initiate an equalize charge from an AC source. We have several warranty replacement and takeout units on a shelf here, from two installations (including in my own home) where the equipment was replaced after being unable to get it to work reliably. Ultimately, Apollo agreed in writing to reimburse us for the cost to replace their equipment with another brand. They never came through. <br><br>Allan<o:p></o:p></p><div><p class="MsoNormal"><b>Allan Sindelar</b><br><span style="font-size:10.0pt"><a href="mailto:Allan@positiveenergysolar.com"><u><span style="color:#000099">Allan@positiveenergysolar.com</span></u></a></span><br><span style="font-size:10.0pt">NABCEP Certified PV Installation Professional<br>NABCEP Certified Technical Sales Professional<br>New Mexico EE98J Journeyman Electrician<br>Founder, <b>Positive Energy, Inc.</b></span><o:p></o:p></p><p class="MsoNormal"><span style="font-size:10.0pt">A Certified B Corporation</span><sup><span style="font-size:7.5pt">TM</span></sup><span style="font-size:10.0pt"><br>3209 Richards Lane<br>Santa Fe, New Mexico 87507<br><b>505 424-1112 office 780-2738 cell</b><br><a href="http://www.positiveenergysolar.com/" target="_blank"><u>www.positiveenergysolar.com</u></a></span><o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p></div><p class="MsoNormal">On 10/29/2013 10:32 PM, Kevin Pegg wrote:<o:p></o:p></p></div><blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:blue">Hi Hilton, </span><o:p></o:p></p></div><div><p class="MsoNormal"> <o:p></o:p></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:blue">My $0.05 worth as off-grid is my primary domain. </span><o:p></o:p></p></div><div><p class="MsoNormal"> <o:p></o:p></p></div><div><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:blue">The SW4024 is an excellent inverter, reliable, robust and if you can find another stack them for 240 and will have no issues with the 3 HP table saw (assuming batteries can handle that is).
