Hi William Jay is correct, rebulk will prevent a new bulk charge whether ac power is maintained or applied “cold”. It doesn’t make sense per our accepted and understood definition of rebulk, but we’ve seen this on every Radian/vfxr installed with lithium.Adjust the rebulk up to just below the
Jay:
Thanks for the reply. My understanding is that a new bulk process begins
every time AC power is reapplied. Rebulk only applies if AC power is
maintained after absorption completes. That’s not what is happening here.

On Fri,
There is or was a setting in the mate 3/s that the rebulk volts has a trigger. If the voltage doesn’t get below it it won’t charge (absorb) properly. Fix is to set the rebulk up higher than the charge voltsI don’t know if that’s your issue or not but I have fixed this on systems. JayOn Jan 12,
Have fun, looks promising

Good Morning Everyone,
The graphs look like something is bypassing the absorb timers. I haven't
been at Outback for a long time now, but from my experience, this can be
caused by the FNDC, end amps programming of the FM Controllers, or the
operating mode of the inverter.

I found a 4U wall mount rack on Amazon that looks like it will carry the
weight. I'm going to give it a try.

Have installed the EG4 batteries in a non-rack mount when they were out of
racks. Inexpensive metal racks from Home Depot or Lowes ( husky racks) could
hold 4 to 6 batteries. A shelf is possible but the battery weighs 100+ lbs.
They now have a wall mount system though it is roughly
I definitely considered this, but the EG4 100aH batteries are rack mount. I
need to wall-mount a battery or put it on a small shelf.

You might want to look at the EG4 battery. They are a bit higher on the AH
but good batteries and reasonably priced

I'm looking for a single battery meeting these specs to pair with an EG4
inverter for off-grid use.
Anyone who knows someone who can ship me a single unit at a reasonable
price, please let me know (off-list, ok).
Thanks,

William,
This is a very timely question, I have been seeing the same thing. I also
don't allow any Flexnet interference in charging. I went to investigate a
site yesterday and figured this one out.
It turned out that the Flexnet was uncalibrated by about 1V on the low
side. This was a Lithium
