YEP, you need a hub 10.3 to work properly with a Mate 3S. And the hub 10
jumpers may need to be reconfigered from the factory positions.

Hi Dave,
Only thing I would check is to see if lowering the eq by 1 volt changes
anything. IE the batteries are just struggling to keep up.
But the CC should tell you what mode it’s in right? IE is it regulating or is
it full power. Either in the menus or just looking at VMP/watts
If it’s
Hi All
On OutBack inverters the EQ process is not temp comped.
The eq timer will not count down until the voltage set point is achieved.
You comment on the issue being somewhat intermittent is interesting.
Could there be a loose cable, bad crimp or corroded connection somewhere in the
system?
I would tend to agree with Ray's analysis, with one question:
- Does the Eq timer reset to 0 when the voltage dips? It should
basically hold the time the batteries were at Eq voltage when it drops
below, sort of putting the EQ timer on hold until the voltage comes back
up. So
I would add to the chorus that it probably is a battery issue. Here are
the symptoms that lead to that conclusion:
A) it started occurring recently,
B) it is somewhat intermittent,
C) the system has aging L 16s (failures at 4 to 5 years are pretty common)
D) they are the Trojan RE series
Steve and Jerry,
Thanks for the suggestions. I'll have to take a closer look at the battery
bank next time I am out there.
The solar setup is 4 strings of 3 kyocera 270's into each charge
controller. So that is almost 65A @50V coming out of each charge controller
for bulk. The parallel battery

I know the old FX's didn't temp compensate in EQ mode but the charge
controllers do... I know... that is what I said when I learned this years
ago!
I don't think the Radians observe temp compensation while in EQ either...
That would be a better question for Lones Tuss... You out there Lones?
Sounds like a battery issue at first glance, as you EQ a battery it gets
warm or even hot and this will effect ability to charge. If e en one of the
L-16 is not exactly the same voltage you will not get to EQ untill another
battery over voltages to show your overall volts. Need to look at each
Brian,
I had tried lowering the EQ voltage by 0.4V. The batteries still get up to
the EQ voltage, but then fluctuate right at or 0.1V below.
Dave,
The EQ countdown timer does not count down when the battery voltage is
below the EQ setpoint (even if by 0.1V). And since the timer never gets to

G'Day All,
Recently ran into an issue on a system installed by others. It's an Outback
FW1000 circa 2015 with a twin stack of VFX3648's. The system is offgrid and

it. I'll be adding PV to it in the coming weeks. The system
Does not sound right to me. Usually both Outback and Schneider protect
against uncontrolled EQ time and end EQ.
I think I would remove the
network after the battery is full and test one controller at a time. Might
have been damaged by lightning or gen glitching. Since you say it does this

Sorry you had already answered the first two questions :) What about the others?

What’s the capacity of the battery bank? And the size of the charging sources?
What’s your EQ voltage? Have you tried a lower EQ voltage setting to see if it
does the same thing?

Hi All,
I've got an outback system (Radian 8048A, 2 FM80, 16 Trojan L16RE-B) where
when the customer equalizes, the batteries hover right around the EQ
voltage, but will often dip to 0.1v less. Because of this, the EQ timer
does not count down properly, and so left to its own devices the system
17 matches
