<div dir="auto"><div>I'm hoping to have a single panel for simplicity and charge a 48V LFP battery. The voltage is an issue, however, with the Vmp being too low in most cases.

I could use the currently available Aptos 460W, but I was thinking REC Alpha Pure RX for the higher voltage and beefed up frame with cross members. </div><div dir="auto"><br></div><div dir="auto">Then I need to see if I can affix some grab handles to the module frame without overstressing it. I'm thinking of maybe using some XR10 rails to beef up the long sides of the frame. I'm thinking some MLPE T-bolts could go through the existing mounting points. Then I could affix the grab handles to the side of the rails.</div><div><br></div><div data-smartmail="gmail_signature"><div dir="ltr"><br>Jason Szumlanski<div><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Principal Solar Designer | Florida Solar Design Group</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">NABCEP Certified Solar Professional (PVIP)</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Florida State Certified Solar Contractor CVC56956</span></div><div><font color="#333333" face="Roboto, RobotoDraft, Helvetica, Arial, sans-serif">Florida Certified Electrical Contractor EC13013208</font></div></div></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sat, Aug 16, 2025, 11:56 PM John Blittersdorf via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Jason, I have done several .
