Confusion on battery charging
I am confused about the best practices for charging batteries. For 7 years I had 300 AH of Lifeline AGM batteries, 270 watts of solar and a simple charging system. My old camper has a 110 volt c...

Some controllers will revert to Bulk if the battery voltage falls to some low level during the charging profile, but a passing cloud should not cause this. All that does is make the charging amps drop. For voltage to drop so low in a brief time, there must be quite a load on the batteries, or they are in hard shape, or something is going on.
Post the brand and model of that solar controller so we can read the owner's manual on the subject of its charging profile.
Any chance you have connected to the Load terminals instead of the Battery terminals? The Load connection could have more actions programmed to make it act like that.
14.3 for more of the day is not necessarily a bad thing as such. You still have half the 24 hr day when they are not being charged.
Lifeline AGMs have particular charging specs you can read on line. You got 7 years from yours and did not even come close to following those charging specs. It should work out even better if you did follow them more closely.
