I have a Victron Multiplus 12/3000/120-50 connected to a 200ah Renogy Gel with two + and - 0g wires while running about 16amps the battery only lasts about 2.5 hours before the system says low battery and shuts off. Let the system completly charge to float and still same issue.
I bought a bluetooth dongle to connect to the system to see whats going on and confirmed amps being used I just ordered the MK3 programing unit but not sure if that is the problem.
These are the default settings from the unit so it looks like there are some changes to make but is it that extreme of a differnce I was hoping for at least 8 hours of use.
Any help would be appreciated.
This is what I see after system goes into float.
And this is after a minute or two disconnected from shore power.
Any help would be appreciated still waiting on the MK3 to come in today
