Happy Breffast!
Most list a max charge current. In the absence of information, 0.1C or 3.5A/battery is safe for all lead-acid.
AGM can typically go higher, but I would never go over 0.2C or 7A unless battery manufacturer said so.
In your case, ASSUMING YOU HAVE PROPERLY CONNECTED/BALANCED THE BANK, 5 * 3.5 = 17.5-35A.
It is difficult to properly balance 5 batteries in parallel. Even if you stay under the limits above, imbalance might force one battery to accept more current than the others.

Same question in the other thread: Hard to follow.

Max charging current
What is the maximum charging current for a 12 V 35 amp hour sealed lead acid battery if 5 of them are wired in parallel configuration? The battery states that maximum charging current is 15 A. But does that change since I’m wiring 5 of them together.

All in one inverter
Has anyone set up a MPP 1012 LV all in one inverter. I am in the process of purchasing this inverter and I am looking at manual for the set up on the LCD screen and there are several items on here that I am not quite sure what to set or what they even mean. Going to be using to 200 W solar...

I apologize for jumping around. It won’t happen anymore. Just trying to figure out what to set on this inverter for that setting in order to not do any damage to the batteries or something even worse like a fire. Maybe I’m just overthinking it.
