Re: [RE-wrenches] Surrette L-16 battereis

2015-12-28 Thread Drake 
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.

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. 
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

Re: [RE-wrenches] Surrette L-16 battereis

2015-12-28 Thread Ray Walters 
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.
