How to set AGS after switch from AGM to Lithium?

[longreach]

My understanding is that voltage is not a good way to set up your Auto Gen Start after switching to Lithium. Or is it?
I have the 8048 Radian, Mate 3 and Flexnet and Hub.
Voltage is easiest but I understand capacity is better.
Any help is appreciated. Special thanks to all who take time out of their day to help out.

I don't use AGS, but if I did, it would be SoC.


Voltage driven AGS has two challenges for lithium: the flat voltage curve makes it difficult to pick a reasonable AGS enable point; and it requires the full Absorb phase to execute.
Generally speaking, with AGS for lithium it may be better to just put "$10 worth" in the tank rather than a fill up. SoC supports that, AFAIK. The FNDC can be relied upon to track SoC with reasonable precision, so choosing, for example, 40% Enable and 80% Disable keeps the charge well within the battery's operational comfort zone, while not running the AC source over long.
Just my $0.02.

That makes quite a bit of sense to me.
I basically put 30% and 80%. But I think I might go with your 40%. I already have so much spare that it would be nice to stretch that before lighting the genny.
I set the flexnet to .4 below charged as per the manual. 50 v on the low. None of this means anything as we are SOC not voltage. I enabled the aux contact on Auto. Invert logic at 'no". It didn't switch so that seems good. I corrected the bank capacity to 1000 AH.
The Mate 3 shows 100% on the battery capacity. I will compare overnight. Last night, it went down 20% on the SOK BMS. I'll see how those compare. There are 3 shunts inside the Radian. I enabled them all. Not sure what they are all for.

There are 3 shunts inside the Radian. I enabled them all. Not sure what they are all for.

The GSLC usually has 3 shunts: one dedicated to the inverter, and two for charge controllers.

In OpticsRE main status screen, click the Battery tile in the left menu bar, then select Shunts from the All/Shunts slider. If all three shunts have active loads, it will show up in the graph. If one of them does not have an active load, disable it.

The same info can be seen in tabular form on the Mate by selecting the Battery / Shunts screen.

When I switched from AGM to LFP, energy from AC source (generator) went from 9% of total consumption to under 2%.
