@cinergi this is what I sent tech support, when they asked to see that info.

@kgol you're right, that was a bad example I gave originally, since it appears like the re-bulk value was reached which is why it restarted. But in hours of testing since, it exhibits this behavior regardless of re-bulk (0.1V for example), and/or lower battery voltage. And, in Float mode, it's expected that the SCC pick up the slack when other loads are demanded, right? (eg maybe the battery needs 0W, but the inverter needs 1000W, so why is the Victron sitting there only providing 5W, letting 20A drain from the battery in full sun...)
So anyway, I have a pair of 150/70 SmartSolars for sale now...maybe a Quattro 5000/48/120 if you can pick it up, haha.
Rebulk = 0.6 .. 54 - 0.6 = 53.4 ... which is close enough to the 53.36v in the screenshot. In this instance, I'm not surprised about the behavior. How low does the battery voltage have to go before it restarts bulk?
Your voltage settings are a little conservative. You'll see better results with float at 54.4 and absorb at 56. You won't notice any difference in lifespan of LFP with those settings. You can't effectively balance at 3.4vpc, either.
