Good Morning Wrenches…
I’d like to take the recent Trojan thread to throw this out there!
With the IEC certification, many battery manufactures are being forced to
recommend higher settings to charge their batteries. The problem with off
grid systems, or even some grid back up systems is the
William,
Sounds like the Trojan rep
#1 Doesn't know off-grid equipment if they are giving you a different voltage
for absorption than the bulk voltage setting.
#2 Says that "Absorb Time needs to be increased, maybe from 3 hours up to 4 or
5 hours" - that is unrealistic for day to day off
OK Steve now you got me thinking,
Some would say that's a bad idea!
Using the voltage settings you're speaking of what would you recommend for
equalize charging ?
I have always thought that different settings for different times of year was
logical but you're getting your bulk up you know what
The testing that we have done with our batteries, is well over 90% completed
has actually increased cycle life and performance even at the higher charging
voltages… We are testing at 2.6vpc just for your information, these batteries
have actually tested at over 110% capacity. That being said th
SE, both inverter and optimizers are now compatible with Sunpower? Someone also
told me Sunpower now makes a negatively grounded panel.

Since SunPower began using their Maxxeon cells several years ago, the grounded
conductor—when there is one—is indeed negative. (No grounded conductor while
using TL inverters.)

Steve,
So the message I am getting is even though we are always
installing a BTS, seasonal adjustments are still necessary...to both V
settings /and absorption times? /Definitely, a major part of my job in
off-grid is to assess as best as possible, the customer's system use

Steve,
Yikes, so to confirm, even on your or anybody's double-walled
cells the best BTS location is down the side of the cell. It seems so
thermally distance/insulated from the electrolyte and lead which we are
all so concerned about protecting. I've said this before, no doubt I'm

Hi Steve,
I'm curious about the temp sensor location.
Some OEM's use a bolt on type.
How do you find this for accuracy?
Thanks

What about temperature sensors bolted to the lugs? Surely a physical
thermal transfer over metal is more accurate that the external case would
be?

I have long been a fan of aggressive charge voltages for flooded batteries in
daily cyclical use. As Steve has emphasized, temp. comp. is imperative,
especially using higher absorb voltage as over-voltage at high cell temperature
rapidly reduces cycle life.
It is my observation that most L16 s
