The HUP is a smaller footprint than L16s because it is a taller
battery. We've moded quite a few battery boxes just by raising them and
adding a strip of wood at the bottom.

For the time being, we replaced the failed Trojan L-16 E to keep the
the bank going. We are investigating different options, including the
Deka batteries. A limiting factor is the footprint of his battery
bank. It is in a vented enclosure in his living space. To expand the
footprint would mean major construction. This may be required at some
point.

Following up on this earlier thread, Drake...
Now previously knowing these system details, my advice no longer
applies, simply because FLA industrial cells don't generally come
that small. This is a small bank. If his array is large enough to
properly charge a larger bank (the MX60 can handle around 3,200W at
48Vnom), smaller industrial cells would work. The smallest HUP 48V
system is rated at 845 A-hr and retails for just over $12K, about
what he planned for his nickel-irons.
Any updates since this thread?

Thanks for all the helpful responses.
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.

Drake,
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. www.hupsolarone.com <http://www.hupsolarone.com>. Spend some
time on this website and it will become more clear.

Hello Wrenches,
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.
How are the Surrette L-16s holding up? Would you recommend them as
worth the extra investment?
What is the best battery to use in an off grid system these days.
Thanks,
Drake
