The only thing I would add to William's list of things to do to solve
this issue is that there is a proper sequence in shutting down and
rebooting the inverter, found in Outback docs. There is also firmware
for the HUB but not sure if that would help or is necessary in this
situation.

I don't know if this will help, but there is a setting under the AGS menus
called DC Generator.
There is DC Absrob timer and DC Absrob Votlage.
It's imperative that this is left alone if you are using an AC source, I
find many systems that are doing this the customer or installer freaked out
Lones is correct as usual
The newer Mate3 when battery charging with the generator has to have time below
rebuik or it won’t work.
So your options are to raise the rebulk voltage, this allows more time below
the rebulk, which allows for a complete charge.
This situation is especially often
Yes SOC is a calculation and with proper setup it works perfectly.
This includes changes over its lifespan etc.
However one issue that I’ve found is if you tie the PV to the SOC it does set
up problems and usually creates short cycling, sulfation and premature battery
life.
The fix is:
Go
I agree with William, SOC is just a calculation, that can change with
temperature, age of batteries, and even when the last full charge
occurred. We just had trouble with an inherited Sunny Island system that
only allows gen start settings based on SOC. The actual battery SOC
didn't correspond
Drake:
I would suggest the following course of action:
1. Reboot Mate
2. Reboot inverter
3. Reset all equipment to factory defaults and manually reprogram each
item
4. Update Mate Firmware
5. Update Inverter Firmware.

Here’s a thought: If the system has an FNDC, the charging may be
programmed to terminate at a specific SOC. I have been told by OB tech
support, and I believe this, that using SOC and battery voltage over time
and/or charge taper to control charging is like the old adage, “too many
It will initially go into absorb, but only stay there for 1 hour. He has
tried to get it back in absorb by shutting the generator off.
He turns the generator back on, and it doesn't trigger an absorb charge.
The system will only take a charge from the generator for 1 hour each
calendar day.
Hello Drake
Have the customer initiate a new bulk cycle from the Mate3.
Do this by
Pressing the Charger button on the Mate3
Select Bulk Charge then Start Bulk.
This will initiate a full Bulk/Absorb Cycle as programmed in the inverter.
If the Absorb time is set to 2 hours that is what will happen.
Same page with you Jay, as usual...
Does the battery system go to absorb with solar still even if it is
cloudy? Maybe a bad battery? Tis the season!
Can the user go thru the set-points and make sure nothing has changed? Gen
sets can do weird surges that can corrupt settings.
If he has to
Happy Friday, Mechanix~

said the possible culprit is inverter firmware per Outback; I wish to add a
data point & follow up questions:

You said both, it will go into absorb for an hour only and it will net go
into absorb. Which one please?
Is there an AGS?

Hello Wrenches,
An off grid, Radian / Mate 3 system we set up some years back has worked
flawlessly. The client is now reporting that his system will only go
into absorption charge for 1 hour per calendar day. The setting was
previously to absorb for 2 hours.
He has tried shutting off the
