I met a guy what says he has them and that he is so glad he spent all that money as now he hardly has
to concern himself with the PV system like he used to.
He seems to use them a lot and has an indoor plant growing operation that uses a lot of power all the time,
24 hours a day sometimes.
So, if I had the cash I would check them out.

No experience, but did have a look at the manual and yes there is no reference to absorb charge settings. From the manual you get the impression these are "standby" type batteries that are usually in Float and on the occasion that they are used/discharged that you charge them through an equalisation charge. Clear as mud...??

- Absorb: 54.8
- Float: 52.8
- Equalize (turned off but I set the value just to be complete): 62.0
Again while I'm very pleased with the performance these numbers feel a bit "low" to me. Maybe not; maybe it's just me.
Anybody have some thoughts here?

Inverter Absorb: 55.6V 4 hrs
Charge Controller Absorb: 55.8 4 hrs
EQ: 56 24 hrs I use EQ to run the freshening charge cycle as necessary.
Battery Ah: 2350
Charged Voltage: 55
Charged Time: 2 min
Return Amps: 47
Charge Factor: 94%
If the FNDC is not showing charge parameters met at least once a week I suggest you increase the absorb time. If the battery bank is >77°F do not exceed 56.4Vdc.
Make sure you have the outback temp sensor stuck to the front of one of the battery cells in the middle area of your bank.
