Over the years we have found that customers will operate 2 to 3 kW inverters just to run 50 to 100 watt loads. Most of the time the inverter AC is also connected to many parasitic loads. Combine that with the low efficiency of operating a large inverter at low power and the following makes much sense. </div><div><br></div><div>We recommend and install small dedicated sine wave inverters. For instance, a refrigerator needs power 24/7. A well made inverter, like an Invertek 600 watt, can power this load and leave the main inverter off line. Lots of people are using CPAP breathing machines all night. For under $100 we can put in a sine wave inverter that does double duty during the day charging laptops, shavers, toothbrush or any small load that needs to operate for extended periods. This has worked very well in conserving power.</div><div><br></div><div>Just some food for thought.<div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Sans'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="font-family: Helvetica; font-size: 12px; "><div><div>Kindest Regards,</div><div><br></div><div>Larry Crutcher</div><div>Starlight Solar</div><div>(928) 941-1660</div><div>Renewable Energy Products, Service and Installation</div><div><br></div><div>Mailing Address (NO SHIPPING):</div><div>11881 S Fortuna Rd.</div><div>#210</div><div>Yuma, AZ 85367</div><div><br></div></div><div>Shipping and retail store (NO MAIL):</div><div>2998 Shari Ave </div><div>Yuma, AZ 85365</div></span></div></div></div></div></div><div><br></div></div></span><br class="Apple-interchange-newline"> </div><br><div><div>On Apr 21, 2009, at 8:04 AM, robert ellison wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Does anyone have a power curve for a DR 2412 inverter?</div> <div> </div> <div>I need to show a customer that it is not 94% effecient with a 10 watt ac led pluged into it alone. </div> <div>I am betting that it needs 500 watts to get into the 75 or 80% range. </div> <div> </div> <div>Thanks,</div> <div>Bob</div></blockquote></div><br></div></div></body></html>
