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
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
Hi Tump,
FYI HUP industrial, on the 12v batteries, use bolted buss bars.
But many of the other industrial motive batteries ( like the HUP) are welded.

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.

Individual 2 volt cells does allow one to bypass that "bad" cell & wait for a
replacement without disabling the whole system. Unfortunately few folks are
comfortable or aware how to replace a "welded in place"cell interconnect w/ say
a HUP battery.
As far as DEKA batteries I recently visited the
I agree with Tom here about 2 strings.
And I have been told more than a few times in the last 22 years, from battery
folks that there is no substitute for lead, in terms of capacity or longevity.
Here is a comparison I worked up for a job just the other day and I’ll let you
figure out which
I have used the nickel iron and have hsd great results. If your customer is
looking long term it might be an option. They do work better for 48 then 12
due to voltages of the batteries

Dan,
That problem of no AC at remote sites while waiting for replacement
batteries is why I always recommend at least two strings paralleled
through a buss bar rather than across terminals. That way if one
battery or cell fails in one series string you can very easily remove
the string from
While I also advocate single strings and minimizing parallel strings when
off the grid, single strings have one big problem, especially in more
remote areas and especially with 6 volt batteries - 1-4 weeks downtime of
the whole AC side of the system while waiting for a replacement battery

I should add that my response was not intended to implicitly

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 inves
While I have no experience with HUP, I do have many years of experience
with Rolls/Surrette. They are a robust battery, and in my opinion superior
to Trojan and other mid-line flavors. I am not as adamant about staying
away from L16s as Allan, although I'd whole-heartedly agree with keeping to
one
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. Spend some time on this website and i
