Recently I was experiencing issues with a 4 months old AGM battery, I've been using the default AGM Battery Type settings for my MPP solar 12v system and after 4 months it only activated the cut off voltage one time, after that the battery seems to be discharging way faster and the low voltage cutoff function activates again couple days after, at night even when I was using just my router, that never happens before, I could let the inverter on with the router until morning and still have 12.6V on the battery.
I figured out that adjusting the low voltage cut off won't take effect unless I change the Battery type settings to User-Defined, but it was too late until I figured out this. I contacted MppSolar support and asked them to provide me the information about default parameters for Battery Type AGM for float, bulk, and cutoff voltage, that was the answer:
Also, I think I could set the bulk charging higher for the AGM battery. I wish to know what are the recommended settings for AGM batteries for float, bulk, and cutoff voltage since I can only find advice for lifepo4 ones.
Greetings to everyone!

- Float charging = 13.5V
- Bulk Charging = 14.1V
- Low Voltage Cut off = 10.5V
