question

hi, the idea that come automatically to me is have you upgraded the firmware? ..what kind of 12v battery you have for this high voltage setting? ..have you found something since your question?

your wiring is good confirmed?

hi, i has tried the simulation for my lithium batteries bank with lithium selected for the type of battery and the floating stage was disabled automatically.. have you selected, in your setting type of batt, the lithium?

I am trouble-shooting the same or similar issue. I have a Battleboard 100A battery, and an MPPT100/30 set to Battleborn's settings, with current firmware. I found recently that my battery was not recharging, and due to occasional loads, had dropped to ~80%. The charger was in float, and per BBs settings, float was 13.6V, less than the 13.8V in the battery, so no charging was happening. I pushed the float setting to 14.6V, which I confirmed with BB was okay, since the battery will be able to "rest" at night, and it's charging again. But I haven't gotten a good answer yet on how it gets into this state, and why BB's recommended settings seem to work for at least most of their customers, but not for me.

Have you resolved your issue? If not, your float and absorption voltages are set at the same, when for most systems float is a few V lower.

Hi @KSmith - I am having the same issue. Did you resolve this ever?

did all this start after the update/

Hi, I have exactly the same problem with my 100/20 charger very annoying and no solution.

I too have this issue with a 100/50.

I have this as well with the 100/30. Only way to fix for me is to completely reset the mppt by disconnecting both the PV and the battery :\

I had this problem, it charged to 38% and then stopped charging and went into FLOAT. I figured out it was actually an error on the capacity indicator. It was actually at 100% but displaying 38%. This can be reset by holding down A/Ah (middle button) and then % (right button) for 3 seconds. It should reset to 100% which is a true reading (hence it’s in float).

I too was having issues with the 100/30 mppt, lol to the point I even fitted another solar panel, yesterday I decided to sort it, got on the roof of my swift caravan and started disconnecting my solar panels one by one and checking the voltage, all seemed fine? went to my controller which said it was putting out 13.9 odd volts tested it and it was, tested my bus bar down under my seat and it was saying 13.4v, so I turned up the absorption voltage in my app in the end to 14.5 which the controller was indeed putting out, but down at my bar it was now only 13.5v?? so clearly the wiring already installed to my caravan was not fit for this setup. routed a new wire direct from mppt to the bus bar plugged everything back in and omg this mppt controller (I've had for nearly a year) is a beast! now have little to no voltage drop reset back to factory lipo setting and now when my batteries are 100% and I turn on a load like my fridge and some lights, the controller almost instantly matches that load by allowing in as much solar as it needs to run the load but not put any more charge in the batteries (obviously this is only done when there is enough sun) but you can see that if there is enough of a v drop between the mppt and the battery the mppt controller will not work as it should.

long winded sorry but check the voltage coming out of the controller then at your battery.

Big fat wires! voltage drop is your enemy

Yeah, this happens to me too. I have to reset the MPPT. Hopefully I notice when it's going on so I can have power for the night. I paid a premium for Victron and have been EXTREMELY DISAPPOINTED with all the issues. All my cablling is to spec and this sort of thing should not be happening.
