It would take me a minute to remember what the difference on the software would be. I installed the 18KPV with indoor EG4 wall mount batteries and on the ENVY, I used the eForce batteries. Both are very sweet setups. The eWay is WAY better than the EG4 gutter. </p><p style="margin: 0px; font-width: normal; line-height: normal; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;"><br></p><p style="margin: 0px; font-width: normal; line-height: normal; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;">The Guardian (sold separately or it comes with the eWay) gives the ENVY a bit of advantage since you can actually see each battery condition in detail. I wish the Guardian was more capable, it would eclipse the similarities in the inverter firmware. The Guardian has I/O like relays, etc and can hopefully be accessed in the future for what they logically would be needed for. The Guardian has a separate app than the ENVY. I wish they would combine them or at least combine on the website version. </p><p style="margin: 0px; font-width: normal; line-height: normal; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;"><br></p><p style="margin: 0px; font-width: normal; line-height: normal; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;">It would be swell to make a list of wanted standard features from each of the AIOs and compare who has what right now. I can feel a spreadsheet coming on now. I made one for lithium batteries already. </p><p style="margin: 0px; font-style: normal; font-variant-caps: normal; font-width: normal; font-size: 12px; line-height: normal; font-family: Helvetica; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;"><br></p><div dir="ltr">Thank you,<div><br></div><div>Maverick</div><div><div id="AppleMailSignature" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px;"><div class="ApplePlainTextBody"><br></div><div class="ApplePlainTextBody">Maverick Brown<br>Off-Grid Solar Commander since 2006<br>Maverick Solar Enterprises, Inc.<br> • Solar Commander Remote Power<br> • SunFlow Systems Cathodic Protection <br>maverick@mavericksolar.com<br>512-460-9825</div><div><br></div></div></div><div><br></div></div><div dir="ltr"><br><blockquote type="cite">On May 15, 2025, at 5:07 AM, Jason Szumlanski via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I was highly against EG4 early on with their direct-to-consumer model, DIY focus, and support model.

<p class="MsoNormal"><span style="font-size:11pt">Hi Wrenches, <u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Really great information sharing on the AIO’s!
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">My experience in the off-grid world, EG4 products & support has been excellent. Started using them last fall, 12 installs done with the 300, 600XP, 12000XP, 18kPV units so far. They all just worked out of
the box. All paired with new EG4 batteries, and I really see no reason to cross brand, as it’s a pretty elegant solution, full monitoring of everything in one portal. The EG4 monitoring portal is slick and very well designed and easy to use for all installer
/ client. There is a new generator control app being developed that will solve complaints about the factory AGS which is extremely basic. Concerned about failures? Buy a second unit to keep on hand. It’s still lower cost than doing an XW or Radian config.
<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">A wise person on this list I can’t recall said something like ‘the winner in the AIO inverter competition will be from customer service”<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">I had a few tech support questions mostly my learning curve. My calls were answered and the solution solved in a matter of minutes. I was gobsmaked at the idea of being able to immediately reach someone at
tech support, who actually knew the product, didn’t bog me down in a bunch of paperwork BS, just dove in and solved the problem.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Comparing to the past 5 years of product quality going rapidly downhill, this is just such a relief. We saw 75% failure rates on Schneider gear. It all had to be tested in the shop before deploying. And then
the days long nonsense of trying to reach ‘tech’ support. Then Magnum quality tanked & shut down. Then Outback vanished (ironically, same guy who owns EG4 bought OB). One by one all letting us down giving us poor quality hardware, and we as the interface to
the client, had to deal with the fallout. It was incredibly costly for us. <u></u>
<u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">So I am hopeful of this new trend of hardware that just works and can spend more time installing less time repairing & replacing new units.
