Hello wrenches,We have a Fronius IG3000 that chronically and frequently cycles into and out of a state 104(grid frequency not within admissible range). The utility has monitored the supply and claims to have found no frequency or supply issues. Fronius sent a replacement inverter but the error
Jeff-
See if you can find a PowerSight power meter (http://www.powersight.com/;
in PG&E territory, we can borrow them from PG&E for free). This will allow
you to log and chart frequency. Present your data to Fronius, and assuming
that your grid frequency is actually within permissible range, push t
Friends:
Has anyone used the Trojan 2 volt L-16 batteries? They each have 3 cells,
I presume in parallel.
The question presents: Although you can divide the strings by three, there
are still an equal number of batteries and cells to maintain and to get out
of whack. Will these batteries b

I have wondered about this as well, why don't they just make a big 1110 AH
cell? Which as you point out would be less caps to feed and less chance of cell
imbalance as well. I do like 2V cells over 6V but this question bothers me.

Tom, big cells are really the way to go, rather than too many parallel
battery bank connections. That is for darned sure, Methinks the issue is
delivery weight. Was considering a back-of-pickup-truck winch arm thing
here not too many years back, and then it all flashed before my
eyes...this SU
William, Wrenches,
Thank you for asking.
Indeed the Trojan Premium L16RE-2V is a monoblock flooded lead-acid battery.
The cells inside the monoblock are configured in parallel with internal
interconnects that are factory-welded and typically offer lower resistance
disparity compared to ex
The Rolls L16 series 2 vdc are single cells. They come in three AH
capacities @ C20, the S-1590 being 1200 ahr. I will say I have not good luck
with the lowest capacity S-1380(1050 ahr). Won't hold a charge after only 1
yr in service at recommended charge rate.

Tom:
To answer your question below: because it would only be 2 volts.
Best case: for a 48 volt system you need 24 cells, period. This way they
are all in series and not separate strings. In separate strings, one
string will be dominant and others will be subsidiary, over time.
The benefi
At least the imbalance would only be one cell, not a whole string of cells.

Yes, indeed. But--- would one defective cell bring about the early demise
of the other two in the same case? If this occurs after one year of age,
are we advised against changing out the one bad battery and required to
replace all of them?
More questions seem to occur the more we thi
William,
It is not recommended to replace one bad unit by a new one in a 1 year-old
battery bank. That will definitely unbalance the strings.
Modern solar chargers and inverter-chargers typically have settings adjustable
to reset to handle a previously 48V battery bank configuration into a 46
I too like the big single cells. I have used many of the Deka 1360 AH 2 volt
cells with good results over the years. All as a single string with welded
interconnects. The welding is an art but kinda fun to do.
Want to clear out the owner, just light the torch!
I have had bad luck with the Dek
Generally speaking, I've been using L16s as beginner batteries.. something for folks to learn on. as soon as they do, I push large 2 volt cells. thin plate technology is just not that forgiving. dbDan BrownFoxfire Energy Corp.Renewable Energy Systems(802)-483-2564www.Foxfire-Energy.comNABCEP #09290

Jeff,
Is there any chance the utility has recently implemented a remote
meter reading system? The Aclara
TWACs remote meter reading system communicates by putting a
pulse on the line that is very near the zero crossing of the
voltage waveform. Unfor
