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.<br>

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.

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.

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>

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>
