Thanks for all the helpful responses.<br><br>
The battery bank is composed of 8 Trojan L-16E batteries in series with
around 2.6 kW of PV on an older 48 V Outback system with one VFX 3648 and
one MX-60. I did not install the system, but I did supply the faltering
bank of replacement L-16s. <br><br>

Your request is missing specifics so my answer can only be generic. Get
away from all L16s. Go to one string of industrial cells. There are
numerous well-respected brands. I would put HUPs at about the top.

Even after my clients have learned to maintain their batteries properly,
the Trojan L-16 batteries continue to crater, one cell at a time. One
client is considering spending $12,000 on a nickel - iron battery bank he
found on the web. This seems like a ridiculously large investment, but he
is feeling desperate. We urgently need another option from the Trojan
L-16s.<br><br>
How are the Surrette L-16s holding up? Would you recommend them as worth
the extra investment? <br><br>
What is the best battery to use in an off grid system these days.
<br><br>
Thanks,<br><br>
