There are other companies making \u201csolar pump inverters\u201d to run standard 3-ph. pumps. And, that IS the way to go for systems of this size. </div><div class=""><br class=""></div><div class="">Another supplier in USA is SunPumps. Another is GenPro (Lorentz distributor).</div><div class=""><br class=""></div><div class="">How to compare them? The inverter will represent a small proportion of the system cost, so I would have to ask each prospective supplier to produce a system design for you. Compare them carefully in regard to how they are expected to handle less-than full sun conditions. Also \u201cbells and whistles\u201d can be extremely helpful, meaning data-logging and remote connectivity and control features. Another rare feature is the ability to handle both solar and backup power sources, not merely by transfer switch or relay but by blending them with solar priority.</div><div class=""><br class=""></div><div class="">Lorentz has been the leader in these features, but others have been catching up. I hope you (and others) will report back about your findings! I\u2019m still researching this field form my upcoming book.</div><div class=""><br class=""></div><div class=""><div style="font-family: Helvetica; orphans: 2; widows: 2; margin: 0px;" class=""><span style="font-family: "Marker Felt";" class=""><font size="4" class="">Windy Dankoff</font></span></div><div style="orphans: 2;
