<p>My 2 cents are each client is different and if they have been fine on that one set of batteries then do what is in their interest. An inverter is easily replaced. I might also suggest to stay with the FLA and avoid possible issues with LFP. No matter how good they are in many cases, they still have electronics in them that can fail and cause a new way to lose power offgrid.</p>
<p>In my case and quite a few of my offgrid clients I want a complete back-up of the battery if LFP is used. That is what is so nice about having multiple battery systems. One can fail and each has it's own BMS. A spare LFP system can also sit for a year and be fine as long as it gets some exercise. Good Luck Howie! All good on those two Schneider xwp and gateway/insight2 systems?</p>

<div>I get what you are saying Jerry, but this client ( a retiring teacher in a very rural, low wage school district, sadly) has lived very lightly off-grid (1kW solar, 24v Rolls KS21s original batteries) for 18 years years and has no pressing need to upgrade his VFX3524 inverter. I'd rather find a good 24volt option to compare a straight KS21 replacement to. I know the inverter could crap out at any time, but if it ain't broke...</div>

<div dir="auto">Dollars and sence, drop the 24 volt, BPI is a great battery. Once l show my customers all the benefits of a 48 volt upgrade it wins every time. I am not talking about busses, RV's and one night stands l am talking about off grid homes. </div>

<div>Hi all,</div>
<div>I've been using BlueIon batteries recently both on- and off-grid, and really like them so far, although I have limited time on them so not a ton of experience yet. I am wondering what folks are liking for 24 v LiFePO4 battery options. I have 24 volt off-grid clients who are not ready to swap out to 48v, but might be interested in Lithium batteries. TIA,</div>
