<div dir="ltr"><font size="4">I took a look at one my customer's garage usage, I was not there, but Egauge said total load when opening or closing the garage door, was 650 watts for about 30 seconds. meaning 5.6 Wh for a single operation. twice a day 22.4 Wh daily use two open and close cycles. but I see a background load besides the light, (LED about 7 watts for 3 minutes= 0.35 Wh). There is a background load of about 100 watts, Possible the radio receiver? or? This is the gorilla in the room. 100W for 24 hrs is 2400 Wh. So if this is correct the pushbutton is a real problem. perhaps a button on the door to open instead of radio? </font><div><font size="4"><br></font></div><div><font size="4">Also using the 7 day to 50% rule at 25 Wh/day the battery will need to be 30 AH @12 volt and the solar module would be 90 watts using 2 SSH/day </font></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 1, 2018 at 2:18 PM, Jerry Shafer <span dir="ltr"><<a href="mailto:jerrysgarage01@gmail.com" target="_blank">jerrysgarage01@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div>John<br></div>Samlex makes small pure sine wave inverters from 12 to 48 volts and down to 150 watts<span class="HOEnZb"><font color="#888888"><br></font></span></div><span class="HOEnZb"><font color="#888888">Jerry<br></font></span></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jan 31, 2018 at 5:23 AM, Dana <span dir="ltr"><<a href="mailto:dana@solarwork.com" target="_blank">dana@solarwork.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div link="blue" vlink="purple" lang="EN-US"><div class="m_5291734025374578458m_-818877057622188617WordSection1"><p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Century Gothic",sans-serif;color:black">Wow, this is flash from the past\u2026 I had almost forgotten about running DC in a house or garage.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Century Gothic",sans-serif;color:black">With todays inverter efficiency\u2019s & costs VS. the cost of proper DC wire sizing, garage lighting?, & having to modify a reliable lift system, etc.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Century Gothic",sans-serif;color:black">Is there really a cost savings in the longs run?<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Century Gothic",sans-serif;color:black"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14.0pt;font-family:"Century Gothic",sans-serif;color:black">It\u2019s a garage, are you going to need to run any AC tools, battery chargers?
