Hello Wrenches,
Have a client with 24 x Rolls S550's. 2 of the batteries have given up the
ghost. Rolls will replace them under the pro rated warranty.
The issue us, the client is wanting to replace them with non Rolls batteries to
save $. They can get 400AH 6V L-16 form factor FLA batteries fr
Daniel,
If it was me, I wouldn't do it. The biggest issue is that dissimilar
batteries (as well as different age batteries) have different internal
resistance. This will only exacerbate the problem with running multiple
strings of batteries - that is they will charge and discharge at different
ra
Daniel:
I feel your pain: In October of 2021 one of our off-grid clients had
failed flooded L-16 batteries. We needed 16 replacement batteries and
chose Rolls VRLA batteries. We could not get 16 due to supply chain
constraints so we went for 8 with a back order for another 8. It took
until M
My 2 cents: L16s are not a good choice in the first place. Compare the
cycle life vs cost.
2nd that sounds like way too many batteries/ strings and definitely a
candidate for larger format 2 v cells or Li+.
I second William's idea of creating 2 strings of the best cells, and
start shopping fo
Hi Danny
Lots of variables. As the warranty is over, that is no longer a concern to
deal with
The fact that you’ve had 2 go bad at the 5 year point, usually means you can
expect other failures soon.
There are 2 options I’ve done.
1. is to hi grade the battery bank into best 16 batteries, but
5 years old on 3 strings, it might not matter to mix, better get ready
for a new bank.
I have never used more than 1 string for my clients and get closer to 10
years life, so maybe there is better advice out there.
Good Luck!

Hello Wrenches,
Now that Schneider has phased out SCP, what are the options for a GUI
onsite for non-savvy consumers?
Thanks!

You should tell Schneider this! I have been for a year now. There was
not enough SCP memory for new XWP functions and a component became
unavailable.
The Connext Home and Facility are definitely not for the non savvy as
you say. They are easy for most to install and the non savvy can have i
Eric Benstennof SE demoed a pretty slick replacement that he cobbled together
from off the shelf parts using a small tablet.I saw it in Jan at an Alt-E

but it is basically an inexpensive android tablet, a USB charging w
The key word there is Cobbled. The off grid or grid interactive (battery backup
in case of grid down) world really needs to rely on a smart phone?
Why couldn’t Schnieder go the extra step and put a display “with enough memory”
to support legacy and XW Pro equipment on the Insight product family.
