Big Solar + Tiny Solar panel in parallel
Put in 380W solar + Rogue MPPT a while ago. With no loads, in storage, the Rogue should go through a daily cycle: Rest at night, very brief MPPT in the morning up to 14.8V, then very brief Absorb ...

Good to see it now works right. 13.2 is sometimes the set voltage for going beck to Bulk with MPPT controllers. ISTR you said the Rogue makes that trigger to be the same as the chosen float setting?
Some have a time in there so Vbat has to be under the trigger for a minute before it will go to Bulk/MPPT. So I suppose if your 13.2 is float and trigger it can take a spike below 13.2 and not go into bulk. Seems kind of tight.
If the solar is still capable of doing more amps then any loads up to a point will not disturb the float, but if the loads are more than the solar can do, then with some controllers that have a separate float setting and a trigger setting less than that, what happens is the Vbat slides down to the trigger and then it goes MPPT/Bulk
With those two settings being the same value, it would go into MPPT/Bulk a minute (if that is the time) after the solar can't meet the demand ? Could be a bit "trigger happy" if you have an intermittent load when the sun is not very high?
