At the C8 rate, a 2-cell T-105 bank can be charged at 26 amps. Is your solar array putting out more than that? Looks like the setup you just described above is only ~12A (153W).

Yep, no problem with this setup, or even the full 200 watts - which I could get with a switch to MPPT. (Max would be close to 15A in that case).
I started this Thread with a proposal for vastly more PV power basically, 2 * 240W (24V panels). In that kind of configuration, 35A would not be impossible - and that could lead to temp sensor "throttling" of the Bulk charge cycle, unless I also did a big upgrade to the battery bank.
