If you size a backup system for central air conditioning, sometimes it is technically possible to heat the pool off-grid in the winter because the house load is otherwise a fraction of what it is in the summer months. In the winter, we sometimes see batteries full by 9:00 am and a lot of wasted solar energy.</span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></span></div><div><span class="gmail_default" style="font-family:arial,helvetica,sans-serif"></span></div><div><div dir="ltr" class="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><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Tue, Feb 18, 2025 at 11:56 AM Dave Angelini Offgrid Solar 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:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div style="font-size:12pt;font-family:Verdana,Geneva,sans-serif">

<div>Greetings wrenches,</div>
<div dir="auto">In Pacific Power territory we are coming up against roadblocks with regards to whole house battery backup systems with inverter ratings higher than 25kw. Even when the generation capacity is below the 25kw residential limit, net metering applications are being rejected based on the inverter rating.. The inverter rating in these cases is sized to handle the customer's existing loads and will never export more than the 25kw limit dictated by Oregon PUC. I am drafting a letter to Energy Trust, the state, etc. But am curious if anyone else gas had this problem or come up with a solution. I would appreciate to hear any experiences or similar interactions with PGE or PPL or even how this has worked in other jurisdictions, states, etc. Any input or support is greatly appreciated.</div>
