<div dir="ltr">And can't you just wire up the new inverter as a "dumb" battery charger only? If you don't need to double KW to loads, don't try to stack it, or connect it to the hub. Just cable it to the batteries, and wire the genny to it's AC in. NO AC out wiring. When genny is running, it should charge fine. A last resort.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Mar 20, 2022 at 10:14 AM John Blittersdorf <<a href="mailto:john.blittersdorf@gmail.com">john.blittersdorf@gmail.com</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">Wrenches, I just added a 2nd VFX3648 stacked as SLAVE L1 to increase charging of his new eVault 18.5 from 12kw Kohler gen. It connects to the generator but doesn\u2019t charge. I read in the manual that both inverters must be the same firmware revision. Once hooked up I found that the added inverter was rev #68 and the original one rev 61. Would it be possible to switch which inverter is the master and have the newer one recognize the older one.? Otherwise is my only option to put a new control board in the original inverter? And possibly also in the new one. Anyone know what the latest rev or last one was?<div dir="auto"><br></div><div dir="auto">John Blittersdorf</div><div dir="auto"><br></div>
