<div><div dir="auto">Alan,</div></div><div dir="auto"> It appears to me that everyone miss read your question. If your customer does not need a generator, then his solar charge controller needs to be able to be set up for the lithium battery voltage settings. So the inverter simply needs to be 48 volts and has nothing to do with charging battery. You could use any 48 volt inverter and use the MATE. The inverter would only provide LBCO to protect the battery. As far as a used VFX 3648 contact me off list.</div><div dir="auto"><br></div><div dir="auto">John Blittersdorf</div><div dir="auto"><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Mar 7, 2020 at 8:20 PM Sindelar Solar <<a href="mailto:Allan@sindelarsolar.com">Allan@sindelarsolar.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>Wrenches,</p>
<p>I have a client who is looking at upgrading an older off grid
system that has an Outback VFX3524 inverter to 48V<sub>nom</sub>
in order to use a Blue Ion LiFePo battery. I installed the VFX
about ten years ago and it has worked without any issues. The
client has never had a generator and has enough array to equalize
his FLA batteries with array only, so has never had or needed a
Mate. If I upgrade to 48V with a new inverter, it will most likely
be an FXR3048. First question: Can I use an original Mate (rather
than a Mate3) to set up basic programming with a R series
inverter, such as charger and LBCO settings? Second: anyone have
an older FX3048 or VFX3648 for sale, if the answer to the first
question is no?</p>
<p>Thank you, <br>
