<div dir="ltr">Dana and Wrenches<div>I also have been around for quite awhile and Dana is spot on, we have been lied too to so many times, some from distributors, some manufactures. We still are in the wild west of renewables, Chinese module manufacturers with no clear contact information, inverter manufacturers that say they will alway be compatible with the new product lines up till they are not. We need to be the common sense for our customers, explain some design issues that they may want to avoid and give them solutions. </div><div>Battery technology is what we will all have to understand and see through the mist for the facts not the hype. I will say that we are all out there to do good be good and help our customers make the best decision so when it sounds like an African Prince wants to make you a deal you all know what to do, we are in the same boat with solar separate the good from the bad and keep up the good fight.</div><div>Jerry </div><div>NABCEP PV Inspector </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Jun 3, 2022 at 10:04 AM Dana Orzel 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 lang="EN-US" style="overflow-wrap: break-word;"><div class="gmail-m_8116546341974238699WordSection1"><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif">Having been in the solar biz since 1988 I can, but will not make a list of products that have come & gone; products that have been Guinea pigged on all of us, promises that have been made & not kept, equipment that has caught fire & individuals that have made unrealistic promises to clients that have really damaged the reputations of the balance of those of us who are trying to build a reliable & reputable reputations in a still growing now teen aged industry.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:"Century Gothic",sans-serif">That said I have held back on installing new product introductions & still do on say micro inverters: they get really hot & really cold & the long term reliability of a product that suffers that will suffer in the long run. I do not know of many 5-8 year old micro inverter systems that have not had at least some inverter components replaced. I remember the first micro inverter training class that I attended & the presenter kept using the term mean time to failure, & I questioned this term. The response was that the components used in similar situations should allow for a similar life span. I had this discussion today with a friend who has a unobstructed south facing roof with no shading, with a micro inverter system that is looking at expanding & wanted more micro inverters because he felt the information on what every inverter/module pair was doing was important. I asked him but what fails? The answer was: Not the Module but the inverter that was the weak link.
